COMMODITY MARkET PLACE

“Commodity Marketplace” - The New Service on AMS Online !

The Global Importance of Commodity TradeGlobally, commodities play a crucial role in industrial

production, as they have a significant share in economic development of individual countries, and contribute to industrial booms.

Since the internationalization of mining and global commodity trade, commodity markets have continuously grown. The growing consumption of raw material increases concerns on secure and sustainable commodity supplies of industrial nations and in the global economy. In future, the challenge will be a long-term guarantee for the increasing need for commodities, in order to avoid supply shortfalls and distortion of competition. From the geological point of view, future supply of mineral commodities is ensured. But in terms of planning reliability of enterprises, it is jeopardized by numerous delivery risks. Nevertheless it is expected that commodity trade will gain increasing importance in the future.

The Idea of AMS-Online “CMP”We are planning to use our proximity to raw material

production, as well as our strong network with the global commodity industry as a basis for our contribution to the global commodity supply.

Raw material has a big share of the global commodities trade. The growing demand will lead to the fact that global trade will increasingly take the form of organized market structures. The mining and extraction, as well as the processing of raw material is often done in different countries. This is the reason why we have decided to create the platform called “commodity marketplace”, which will provide a forum for an exchange of supply and demand of raw material.

Dear readership, Dear Sir or Madam,

Gravity DrainageIn gravity drainage, the ground water

flows to the well because of the vertical difference between the ground water level and the water level in the well, i.e. because of the potential energy of the water. This is only possible in rocks with high permeability, in which this potential energy can come into effect. Such conditions can be found in hard rocks with high porosity or in highly fissured rocks. Examples are porous sandstones, highly fissured limestone or basalt.

Soils that allows for gravity drainage are sand and gravel. However, with fine sand, the effectiveness of gravity drainage decreases.

As mentioned in the previous chapter, so-called wells are drilled into the underground and completed, so that ground water can be lifted (extracted).In principle, dewatering wells are differentiated according to the following main criteria:

1. The energy that causes ground water flow to the well2. The depth of the well

In the first case a distinction is made between:• GravityDrainage• Vacuumdrainage• Electro-osmosis

In the second case a distinction is made between:• Near-surfacewell(shallowwell)• Deepwell

Vacuum DrainageIn aquifers with low permeability it is not possible for

water to flow to the well only by force of gravity, like for example in fine sands, since as the water is highly attached to the soil. Therefore in such cases a vacuum has to be created. This method of dewatering is called vacuum drainage (fig. 1), for which vacuum wells and vacuum injection lances are applied.

In vacuum drainage, suction pumps are used. The water is sucked from the surrounding soil with suction pumps. Since these pumps can only achieve a maximum negative pressure of 1 bar, the lift height of water is limited. Vacuum wells have a maximum distance of one to two meters, based on the extent of the vacuum in the soil, and lowering depths of up to 7 meters can be achieved. Due to this limitation in depth, these wells are defined as near-surface wells in technical terminology.

Near-surface wells are vertical wells for ground water lowerings of up to 8 m. Often these wells are connected to a common suction pipe, which mostly is arranged as a ring on berms. A maximum of 3.5 to 4 m of ground water lowering (level difference) can be achieved. Usually the applied well pipes have a diameter of 150 to 300 mm. In addition to the suction pipe, rotary pumps are also applied.

Near surface wells can also be arranged in so-called echelon, in order to further lower the ground water level. (fig 2).

In case the water needs to be conveyed to higher heights, other pumps are needed. The wells that are drilled in higher depths are called deep wells. In order to push the water above ground, submersible motor pumps are inserted to these wells.

Deep wells are also vertical wells, out of which the water is conveyed with electrical submersible pumps from higher depths. Since the water is pushed and not sucked, any lowering depth is possible. The drill diameter of the wells is approximately 400 to 1,500 mm or more, the filter diameter is usually 2200 to 1,250 mm. The filter material is gravel with grainings of 1 -7 mm.

In cases of dewatering soil with low permeability in high depths, a combination of vacuum drainage and deep well can be applied. This technology is called vacuum- deep-well- dewatering.

EDUCATION

Electro-OsmosisArgillaceous and silty soil cannot be

effectively dewatered with vacuum drainage. To a limited extent this soil can be dewatered with electro-osmosis, which means that water is moved with a direct current. The effect of electro-osmosis is based on the fact that although a fluid is electrically neutral inside, at the surface it develops an electrochemical double coating that is not electrically neutral. In case an electrical field is set up parallel to the surface of the fluid, the influencing force on the fluid generates a flow. The water flows from the anode (fig 3), which can be a steel profile rammed into the ground, to the cathode.

The cathode consists of steel filter pipes, which are inserted into the ground in particular intervals. The water can then be pumped from these filter pipes. However, this method is very complex and costly and can therefore only been applied under specific circumstances.

Stability analysis of complex underground structures - from data acquisition to 3D numerical simulation

IntroductionThe rock mechanics and the safety-related evaluation

of underground structures, whether in infrastructure or in the field of mining, requires an interdisciplinary approach. The difficulty of making a detailed prediction regarding the stability, lies mostly in the limited available information and also in the complex material behaviour of the rock mass. This complex behaviour can be attributed to the prevailing inhomogeneous and anisotropic circumstances, which result from their genesis and preloads/tectonics. The required disciplines for a detailed rock mechanic analysis can be fundamentally divided into the four areas: [1]

a.) Surveying,

b.) Geology,

c.) Hydrogeology,

d.) Geotechnics / Rock Mechanics

The first part of this paper illustrates in which way the information of the different fields can be put together to create a comprehensive overall concept for a rock mechanics evaluation. It should be mentioned that the here listed methods are not complete, because they heavily depend on the observed project. The amount of the methods must be adapted and specialised for each project. A representation of the necessary cross-disciplinary knowledge regarding the technical and operating safety management in mining and rock mechanics was also discussed in the article by Dipl.-Ing. H. Weber [2] and em. O. Univ.-Prof. Dr. H. Wagner [3].

by Gunter G. Gschwandtner & Robert GallerMontanuniversität Leoben | Austria

The assessment of long-term stability and behaviour of complex underground structures is an interdisciplinary task which includes the areas of geology, hydrogeology, surveying and

geotechnical engineering. The basis is an extensive investigation of the geological and rock mechanical conditions on site as well as an appropriate testing program and the compilation of a realistic numerical model. This paper gives an example of how these areas, their methods and the acquisition of data work together to create a three-dimensional computer aided model of underground structures. Due to the characteristic of complex underground structures geometric shapes can occur, for which a simplified two-dimensional analysis is not significant. A more detailed 3D simulation should help to identify existing zones of weakness. By implementing data into the numerical simulation it should be possible to provide a time-dependent occurrence of weak spots in the rock mass to be able to initiate stabilization measures in an early stage.

The main focus of the second part is the numerical simulation. Due to a high increase in computing power in combination with the available numerical methods/programmes, creation and calculation of 3D-modells has experienced great advancements. However, to create a coherent and informative model, a connection and coordination of the various areas is necessary.

This procedure from the data acquisition to the creation of the complex model is shown by an example of an abandoned gypsum mine.

Methods of analysis and evaluation of rock machanical situations

The aim is to merge all the available information from the different departments. This information is the basis for a model to describe the rock-mechanical processes and stability. Figure 1 shows a basic overview of the four disciplines geology, hydrogeology, geotechnical engineering / rock mechanics and surveying with their methods and potential of information. An important foundation for a smooth cross-disciplinary collaboration between the different areas is a well-designed data management system in which the information can be found with little effort for further processes.

The following points discuss the various methods used in the investigation of the old gypsum mine in more detail.

SurveyingThe old gypsum mine consists of two levels which are

connected by a ramp. The dimensions of the levels are 160 m by 180 m. The entrance tunnel runs with a length of approximately 205 m in SW-NE direction. The upper level is between 13 m to 16 m below the ground surface.

The surveying and the creation of maps are the basis for further investigations and the prediction of the geotechnical situation. The aim is to get a geometrically correct, complete and unambiguous model of the underground structure and of the surface in the mine’s sphere of influence. [4] [5]

The basic information regarding the surface is available from the GIS (Geo Information System), the land surveying office and the Federal Office of Meteorology and Surveying. In most cases these maps are detailed enough, otherwise further measurements are necessary to increase the resolution in specific areas. Figure 6 shows the surface area above the mine which is also used in the numerical calculations.

Fig. 1:Overview of the four disciplines and their methods, including the information-flow for the geotechnical evaluation of an underground structure [1]

15Issue 02 | 2012



The model of the underground structure corresponds basically to a summary of different maps. This data, however, is usually not sufficient to create a detailed model. In this case further surveying of the underground structure is inevitable. Figure 7 illustrates the 3D model of the underground structure.

GeologyThe creation of a geological model is an important input

for the design of any underground mine as well as for the investigation and evaluation of the stability of old mines. Geological structures including surface and underground mapping have to be studied in detail. [6][7][8] The work includes a documentation of:

a.) existing lithologies,

b.) underground and surface structure regarding the geometrical data,

• interfaces, gaps, stratification surfaces, foliation surfaces, linears

c.) fault zone properties.

Using this information collected in the field in combination with surveying data, geological data corresponding maps can be created, including a 3D model. In case of the abandoned gypsum mine, three different lithologies can be distinguished.

The most common quantitative share in the mine is the clayey-marly-gypsum including conglomerates called “Haselgebirge”. A distinction is made between gypsum-rich and clay-rich “Haselgebirge”. The difference can only be verified by chemical and mineralogical analysis. For this purpose, the following tests can be used [9][10]:

a.) thin-section microscopy,

b.) x-ray diffractometry,

c.) chemical analysis.

Due to its good ductility this rock mass does not show joints. The bedding planes are very indistinct and irregular formed. They have no symmetry relations to the stratification. Therefore, a continuum mechanical simulation program can be used in the studies. Furthermore, some dolomite blocks with a dimension of a few meters are situated in the clayey-marly-gypsum mass. Figure 2 shows the geological map

HydrogeologyDepending on the existing geographical and geological

conditions, the existence of an underground structure effects the hydrogeological conditions and is therefore a relevant factor for the assessment of the geotechnical / geomechanical situation. In particular, the problem of

Fig. 2:Geological map of the mine of the first level

dewatering plays an important role in many mines. It is important to distinguish whether there is a change of the groundwater situation caused by a temporary or a permanent (long-term) cavity or not.

By using existing data from the surveying and geological investigation, it is possible to describe the hydrogeological situation and to determine the hydrogeological catchment area. In addition the existing aquifers and aquifuges can be determined which are used to further describe the groundwater situation. This is important for subsequent investigations of water-sensitive areas. Those are understood as areas in which water-soluble ingredients such as gypsum as well as salt are included. This may have a large effect on the long term stability. Figure 3 illustrates the effect of such a dissolution process to a rock core. The rock sample shows, that, due to the supply of fresh water a continuous dissolution process is established, which damages the sample and thus reduces the strength considerably. Currently the solution behaviour of gypsum-bearing rock samples is investigated at the Chair of Subsurface Engineering at the Montanuniversitaet Leoben. Therefore, an experimental procedure was developed which still is in the testing phase. Not only a loss of material induced by a solution process was able to be observed, but it was also shown that there are particles with a small grain size in the water - for example clay minerals, which are included in the gypsum matrix.

The identification and estimation of the maximum possible amount of solution per year is an important factor for the stability analysis. The evaluation of the hydrological annual cycle and the existing pumping rate (Figure 4) from the mine shows the amount of water, which is responsible for the maximum amount of soluble gypsum, and a possible direct relationship between precipitation, groundwater and pumping rate.

Another issue is the retention period of water in the rock mass. Water with a long retention time under ground is already partially or even fully saturated before it reaches the catchment area of the underground structure. This means that there will occur none or rather less solution processes around the mine. The retention period can be determined by isotope analyses. [11] For the preparation of the hydrological annual cycle and the isotopic studies a minimal investigation time of one year is required.

The petrographic and mineralogical test results from the microscopy, X-ray diffraction and chemical analysis can be used in conjunction with the hydrogeological information to determine the maximum possible amount of dissolved gypsum. Using this information, potential areas of weakness can be identified.

Geotechnics and Rock MechanicsThe area of geotechnics involves the collection and

interpretation of geotechnical parameters, which are necessary for the determination of the material behaviour. Depending on the requirements of the project an adequate amount of laboratory tests as wells as in-situ tests are necessary for the determination of the strength and deformation properties. For this project the following tests have been or will be performed:

Uniaxial compression tests•

Triaxial compression tests•

Brazilian tests•

Creep / long-term tests•

To select the samples, a “sampling-grid” of approximately 20-30 m was used on the first (=upper) level, to ensure an even distribution of sampling places, as shown in Figure 5. Per location four cores were taken which were used for the geotechnical and the geological / mineralogical investigation. In the second level of the old mine there is an underground lake. The water level is between 1 and 2 meters. For this reason, it was not possible to take samples on this level.

Until now 28 uniaxial compression tests, 17 triaxial compression tests and 51 Brazilian tests were conducted. Due to the geological situation (Haselgebirge), the experimental values show a wide scatter of the parameters. As an example, the uniaxial compressive strength is used (Table 1).

Especially for long-term stability analysis, the geotechnical long-term parameters are important. In the old gypsum mine the temperature varies between 8°C and 11°C and the relative humidity varies from 83% to 94%, depending on the season. To obtain realistic parameters creep tests were conducted under the climatic conditions (temperature and humidity) which are predominating in the underground mine. If the climatic conditions were far different from these values within a longer time, shrinkage

cracks could occur. This would cause damage to the rock sample, which would falsify the results. The long-term tests are still in progress at the Chair of Subsurface Engineering.

The parameters obtained from these tests and the information from the fields of surveying, geology and hydrogeology are used to generate the basis for the rock mechanical assessment of the underground structure.

For the first estimation of the stability of the underground mine qualitative and quantitative [12] rock mechanical descriptions as well as analytical methods can be used. Such common methods are for example: RQD after Deere [13], RMR after Bieniawski [14], RMR after Laubscher [15], Q-System after Barton [16] and GSI after Hoek [17]. The analytical methods include a calculation of the pillar stability and a calculation of the stress at the cavity edge. These procedures are not discussed in detail in this article.

3D – Numerical SimulationThe numerical simulation is an important tool for the rock

mechanical analysis of the entire model of an underground structure. During the creation of the numerical model the information from all areas (surveying, geology, hydrogeology and geotechnics) is needed.

The most common approach up to now is to investigate the rock mechanical situation on the basis of a two-dimensional model. The simulations are done from cross sections at important/interesting locations inside the mine. Besides that highly simplified three-dimensional models are studied. However, most of the underground structures have far more complex geometric and geological structures. In such cases a two dimensional approach is insufficient due to the three-dimensional stress redistribution around the cavity. In order to investigate complex structures realistically, a three-dimensional numerical model was created. The simulation was performed using the software ABAQUS 6.10 from Simulia.

Numerival Model:

Importing and preparing the ModelThe raw data from the surveys can not be used

immediately in the numerical simulation. The geometry has to be prepared previously, so it can be implemented without any complications into the simulation program.

In Figure 6 (b) and 7 (b) the “processed” geometry is shown. The preparation of the model mostly includes the repair of areas with a bad geometry surface-mesh and the search for areas (triangles) with corners that consists of small angles (< 10° - 15°). The number of the single face elements is illustrated in Table 2, comparing the surveying model and the prepared model. A further comparison between the two models shows a relatively small difference of 2% regarding the volume and 1% regarding the surface area.

For verification, both models were imported into the simulation program and a calculation, using an elastic material model was performed. It was shown that there are no significant differences in the stress and deformation conditions. However, the not modified model had a far greater number of disoriented elements, with a factor of about 100, compared to the prepared model.

The boundary conditions were chosen so that there is no or just minor influence on the modelled structure. The distance from the mine to the boundary is between 98 mand 136 m horizontally and 88 m vertically. This lies above the required minimum distance of 4-5 diameters to the side and 2-3 diameters to the base. [18]

Material Parameters and Material Behaviour

For a first estimation of the stress and deformations, the calculation included just an elastic material behaviour, which means that the geological conditions were not considered realistically. The second step was the implementation of the geological model (Figure 8). A distinction was made between the dolomite and the Haselgebirge. For the determination of the material parameters the existing experimental data was used. To limit the number of calculations the minimum, maximum and average values of the parameters were used (Table 3-1 and Table 3-2).

The test results show a very high Young’s Modulus for the Haselgebirge, as shown in Table 3-1 / Table 3-2. This can be explained by the more or less ductile property of the rock mass and its low elastic deformation component. For this reason an “alternative” value for the Young’s Modulus has to be used in the calculation. Due to this issue further investigations are in progress to find such an “alternative” value for the calculation. A second possibility is switching to a more complex material model.

Due to the large scatter of the parameters a further aim is to perform a parameter study with parameters for an elastic-plastic material behaviour to identify potential vulnerability in the structure. Also the smallest possible parameters have to be found, at which the underground structure is in an stable condition.

To study the long-term stability a creep model has to be implemented in the model. Since the long-term tests are sill running, the long-term stability is assumed to be 70% of the short-term strength.

Meshing and Boundary ConditionsThe mesh of the model is created by regenerating a

surface mesh, then the volume elements / volume mesh is created. The areas around the underground structure are fine-meshed to generate a higher resolution and accuracy of the stress and displacement distributions. In this case the global distance between the nodes is between 10 m and 5 m at the surface, the node distance at the structure is 0.45 m. The whole model consists of 8,524 million elements, whereas 754 elements are “disoriented elements” (0.0088% of the total number of elements).

For the first elastic calculation C3D4 elements were used. When using the elastic-plastic material model or creep models the element type C3D10 were used.

The boundary conditions of the model were locked in the horizontal direction at the laterally edges and in vertical direction at the bottom. The load was applied by gravitation with 9.81 m/s².

ResultsThe aim of the on-going investigations is to determinate

the position of weak zones and the long-term stability of the underground structure. The primary stress varies between 27.96 kN/m² and 58.25 kN/m² at the first level depending on the overburden. It is assumed that the overburden material consists of Haselgebirge. An additional layer of soil with a lower cohesion was not taken into account. The first calculation was performed with a purely elastic material model to roughly estimate the stress and deformations distribution. Another calculation was performed using the Mohr-Coulomb failure criterion. Due to the not fully available experimental data, this calculation is not discussed here in detail. The maximum stresses are 6.0 MPa (pressure) and 0.80 MPa (tension). The location of the large tensile stress is in the area of the first level (Figure 9), which has a span of 10.5 m. This is the largest span in this mine.

By the appearance and progression of overstressed zones, the areas where support measures must be installed to stabilize the underground structure in a long run can be identified. Furthermore, the model can be used for the investigation of the refilling process and to ensure a smooth restoration.

Summary / ConclusionNowadays a lot of different methods for creating

3D models are available in the areas of geology, hydrogeology, geotechnical engineering / rock mechanics and surveying. The Chair of Subsurface Engineering at the Montanuniversitaet Leoben has set an aim to combine the data, information and knowledge from these disciplines and the numerical methods in the field of geotechnical

engineering. The goal is to improve the rock mechanical assessment of complex underground structures. It has been shown that prior to any modeling the level of detail as well as the extent of necessary information has to be processed carefully between the different disciplines.

As part of this project, further studies of long-term parameters, including the investigation of the numerical long-term stability, will be carried out. Another important question is to what extent the complexity of the geometry affects the stability and the stress and displacement distribution and whether or not it is negligible.

Finally, it is important to note that the qualitative and quantitative descriptions of rock mechanics, analytical calculations and numerical simulations can only deliver approximate solutions of the current situation, even when using the newest available methods and tools.

China is regarded as this century’s economic miracle. Yet for a long time, its stunning growth came at the expense of the environment. But times have changed. Today, the country’s

top priorities include boosting efficiency, reducing emissions, and creating environmentally-sustainable cities.

SUSTAINABILITY BOOMFORMULAS FOR EFFICIENCY - CHINA

At a celebrations to mark the Chinese new year on January 23, 2012, there were many more fireworks in evidence than had been the case in previous years. That’s because 2012 is the Year of the Dragon, which is said to bring happiness and success. As a consequence, the whole country expects birthrates to soar. According to popular belief, children born under the sign of the dragon are blessed by good fortune.

If forecasts produced by the United Nations are accurate, China’s population, currently at 1.34 billion, will reach 1.4 billion by around 2025. At present, with half of the country’s people already living in cities, the economy is growing at around ten percent a year and has been doing so for quite some time. Although this trend has rescued millions from poverty, it has also unleashed an immense hunger for goods, resources, and energy. According to the International Energy Agency (IEA), oil consumption is set to rise by 70 percent between 2009 and 2015. By 2015

China is expected to account for 42 percent of global oil demand. In a similar vein, the IEA estimates that China’s power consumption rose by 200 percent in the past decade and that its water consumption could double by 2030 (see Pictures of the Future, Fall 2011, p. 82).

For a long time, these trends took a toll on the environment. In fact, China is currently responsible for around one fourth of energy-related CO2 emissions worldwide and is already the world’s largest producer of greenhouse gases, ahead of the U.S. According to a 2008 report by the World Wide Fund for Nature (WWF), 16 of the 20 cities with the worst air quality around the globe were Chinese. Yet the country is mindful of this problem and has begun to take action to remedy it. “In 2006. China’s 11th five-year plan mar ked a paradigm shift in the country’s attitude toward sustainability,” says Martin Klarer, who is responsible for corporate strategy at Siemens China. “Environmental protection and enhanced efficiency are now major elements of China’s economic plans.”

Sunshine in Beijing: Things could one day look this bright all over China, thanks to a series of measures including the promotion of electrical mobility or wind power. Today China is the world‘s largest wind energy market.

27Issue 02 | 2012



World Champion Wind Harvester

The use of wind power is a prime example. “Less than ten years ago, there was almost no wind generation here,” Klarer explains; “but today China is the world’s largest wind energy market and home to some of the world’s largest wind power companies.” What’s more, this is a growing market. According to the newspaper Shanghai Daily, in 2011 China generated some 70 terawatt- hours (TWh) - 70 billion kilowatt-hours (kWh) - by means of wind power, an increase of 40 percent over the previous year.

China is planning to install wind turbines with a total capacity of 150 gigawatts (GW) by 2020. That’s equivalent to almost the total combined renewable and conventional installed capacity in Germany. It is also worth remembering that at the end of 2006 China’s wind power capacity was a mere 2.6 GW. In other words, wind energy is a major market of the future in China. As the world leader in offshore wind power installations, Siemens is thus looking to capitalize on this expansion, not least because of the huge potential in this segment of the industry. With shallow waters extending many kilometers from its coastline, China offers ideal conditions for offshore wind farms. With this in mind, in spring 2011 Siemens opened a facility that produces nacelles for wind power plants in close proximity to an existing rotor blade plant. Located close to Shanghai, right on the East China Sea, the facilities have an annual capacity equivalent to a generating output of 500 megawatts (MW).

“We’re supplying not only China but practically the entire Asian market as well,” says Victor Li, head of turbine production at Siemens, China. “For now, we’re producing 2.3 MW turbines; but later we’ll build 3.6 MW models and even 6 MW ones.” The fruits of this labor are already visible in Jiangsu province on China’s east coast, where Siemens has installed an offshore wind farm with 21 wind towers and a total output of 50 MW. “We also have firm orders from other countries, including Thailand,” adds Bjarne Joergensen, head of the rotor blade plant.

28Issue 02 | 2012



Traditional HydroelectricityWhereas the use of wind power is a recent phenomenon,

hydroelectricity has been an integral part of China’s energy mix for 100 years. A century ago Siemens installed generators with a combined output of 480 kilowatts (kW) in the country’s first hydroelectric plant, located in Yunnan province in southwest China. It was the start of a unique boom. Today China has more hydroelectric facilities than any other country. With a combined output of 197 GW, these plants contribute some 15 percent of the power consumed in China. According to the China Electricity Council, around 4,700 TWh were consumed in 2011 - almost eight times Germany’s annual energy requirements.

Nonetheless, the lion’s share of the power consumed in China’s huge cities is still generated by coal-fired plants. Along with the rapidly rising tide of traffic, this is one of the major causes of the country’s serious smog problems. “The challenge is that the majority of China’s hydropower is generated in remote southwest provinces, hundreds of kilometers from the nearest population centers,” says Klarer. The remedy is to use high-voltage direct-current transmission lines. These low-loss lines can transmit huge amounts of power over hundreds or thousands of kilometers.

One such HVDCT line built by Siemens and electricity provider China Southern Power Grid (CSG) has been operating since 2010. It supplies the major cities of Guangzhou and Shenzhen in the southern Chinese province of Guangdong with 5,000 MW of clean power generated by hydropower plants in Yunnan, some 1,400 kilometers away. Compared to the emissions associated with coal-fired generation, the region produces 30 million metric tons less CO2 a year thanks to the new line (see Pictures of the Future, Fall 2009, p. 24).

China’s utilities are planning a crop of additional HVDCT lines, 14 of which are due for completion by 2015. Two of these are being built by Siemens, CSG, and other Chinese partners. Featuring transformers, converters, and other key Siemens components, these two lines will transmit an additional 11,400 MW of clean power to Guangdong from 2013 onward.

Exploiting Savings PotentialAt present, mega cities such as Beijing and Shanghai can

only dream of tapping any form of clean power in quantities such as these. They still rely largely on electricity generated

by coal-fired plants. Here, ways of bringing about a lasting reduction of CO2 emissions include improved generating efficiency, smarter usage of power, and demand reduction strategies - primarily in industry, but also in private households. As of 2008, for example, all Chinese homes have been able to purchase subsidized energy-saving bulbs for a tenth of their original price. In the first year of this campaign, 62 million lowenergy lamps were sold; the figure has since exceeded 120 million. In Beijing alone, there are 15 to 20 million energy-saving bulbs in use thanks to this campaign. Compared to conventional incandescent bulbs, this means savings of up to one billion kilowatt-hours per year.

When it comes to industry, however, the authorities have opted for binding legislation. This is because industrial electric motors are the largest consumers of power in China. According to China’s National Development and Reform Commission (NDRC), they account for around 60

percent of domestic power consumption. “Less than three percent of industrial motors in China carry the Chinese energy efficiency rating of 2 or better,” says Du Bin, product manager at Siemens Drive Technologies in China.

Yet this is set to change. Since July 2011, all industrial motors sold in China must have an energy efficiency rating of at least 2. Potentially, this represents a massive reduction in costs.

“If all the industrial motors in China were swapped for more energy-efficient models, consumption would fall by around 60 TWh a year. CO2 emissions would decrease by 50 million metric tons,” says Du Bin. In collaboration with colleagues in Germany, Siemens Drive Technologies in China has developed a more efficient electric motor for the

hinese market, where it is already being manufactured. “Our motor is designed to be inexpensive, robust, and very easy to operate. Because it also conforms to the standards of the International Electrotechnical Commission (IEC), it is sure to be marketed worldwide,” adds Du Bin.

By distributing around 120 million compact fluorescent lamps, China has significantly cut its electricity bill.

Thanks to high voltage direct current technology, China can use hydroelectric power to reduce air pollution in its mega cities. Above: supports for thyristors.

There is also huge potential for improving the efficiency of China’s coal-fired power plants, which cover around four fifths of the country’s electricity needs. Take Shanghai, for example, with its population of 23 million.

Here, daily power consumption can rise to as much as 20 GW and is currently increasing by around 1 GW every year. In order to provide a sustainable response to this huge demand, city authorities have turned to new technology.

Here, projects include the coal-fired Waigaoqiao No. 3 power plant. With turbines and generators from Siemens, the plant boasts a net efficiency of 46 percent, one of the highest in the world for a facility of this type. This plant, which was commissioned in 2008, consumes around 700,000 metric tons per year less than a standard Chinese coal-fired plant; its corresponding CO2 emissions are around 1.8 million metric tons lower.

China’s most efficient combined cycle power plant, which also relies on Siemens turbines and generators, is located nearby. The facility, which is operated by Huaneng Shanghai Combined Cycle Power Co., LTD, has an output of 1,200 MW and an efficiency of 58 percent.

Commissioned in 2006, its job is to cover the huge peaks in demand that can rock Shang- hai’s power grid on particularly cold or hot days. “Compared to a coal-fired plant, the advantage of a combined-cycle power plant is its enormous flexibility,” says the plant’s general manager Xie Deyu. “The plant comprises three blocks, each with a rating of 400 MW. We can ramp up and ramp down any of these blocks fast enough to cover peaks in demand almost immediately. Last year alone, we had to deal with over 310 such incidents. If we didn’t have the combined-cycle power plant, we’d probably need to operate more coal-fired plants for backup - and that would result in much higher emissions.”

Another flexible option for buffering fluctuations in supply and demand would be to exploit the batteries of electric cars as an intermediate storage facility, particularly when cities such as Shanghai start to make greater use of variable sources of power such as wind energy. At times of either peak demand or low wind, this backup supply could then be reintroduced to stabilize the grid. Obviously, such a system would require a much larger fleet of electric vehicles than is currently available. However, the authorities are now planning to put as many as one million hybrid and electric vehicles on Chinese roads by 2015. To help achieve this ambitious target, work has already begun to provide the requisite infrastructure. At the end of 2011, for example, Siemens installed 140 charging stations for electric cars in Shanghai.

Sustainable City“China has covered a lot of ground in terms of improved

efficiency,” says strategy expert Klarer, “but it still faces big challenges, particularly in metropolitan areas, where the population is set to grow by an additional 350 million over the next 15 to 20 years.” Forecasts indicate that by 2025 there will be around 220 cities with more than one million inhabitants. Many of these urban areas will mushroom out of nothing. “To ensure the greatest possible sustainability, these cities will require integrated holistic concepts rather than the discrete isolated solutions implemented in the past,” Klarer adds. One such concept is currently being realized just outside Tianjin, a port near Beijing. Tianjin Eco-City will provide homes and work for around 350,000 people from 2020 onward. It should also provide China’s urban planners with an answer to the most pressing question of their time: how to build a sustainable city on the basis of a reproducible model under realistic conditions.

Such a project looks viable. Around 20 percent of the Tianjin’s electricity is to come from renewable sources; water consumption will be half of today’s level; and 90 percent of traffic will be based on green forms of mobility such as bicycles, public transport, and electric cars. Naturally, the buildings will have intelligent management systems and good insulation.

At the same time, the new eco-city will serve as a living research experiment. It will be possible to make continual adjustments designed to improve the overall efficiency of the project. In order to advance the cause of green urbanization, the project company Sino-Singapore - a joint venture between the governments of China and Singapore - intends to establish a joint venture with Siemens. The aim is to harness a wide range of state-of-the-art technologies, develop and demonstrate future-oriented technologies, and create a vision that will make Tianjin Eco-city a sustainable and replicable city model for the rest of China.

Last and by no means least, a project like Tianjin Eco-City underscores China’s continuing commitment to enhanced efficiency - and that’s an achievement that is much too precious to be left to the vagaries of the Chinese zodiac

This Herculean task is taken on by the SF 2600i dinting machine. The main reason for operating the dinting machine in the salt mine on a non-stop basis is unevenness of the mine floors caused by blasting and cutting during tunnel driving. In addition, previously rehabilitated floor pavements are gradually destroyed again by the heavy-duty vehicles that are needed for salt mining. In both cases, the floor surfaces are covered with a mixture of potholes, bumps, steps and rutting.

„The effects are quite severe,“ explains Herbert Hesser, head foreman at the mine. „Axles, wheels, chassis and gearboxes of the 150 mobile machines operated in the mine are severely affected by the uneven floor surfaces.

The costly consequences are downtimes, high repair costs and increased parts requirements. When driving on floor surfaces levelled by milling, the mobile machines achieve an average speed that nearly equals the maximum permissible speed in the mine of 35 km/h. On uneven roads, on the other hand, they achieve an average speed of only 15 to 20 km/h. This costs the company money every day.

A lot of valuable time is lost, for example, simply because our workforce needs longer to get to their work

And last but not least, we have a duty to care for the welfare of our employees. For roads allowing smooth and safe travel protect against health risks, such as back disorders. And in the long run, the company in turn benefits from the welfare of its employees.“

All of these cost factors are eliminated by the SF 2600i dinting machine single-handedly. The predecessor model, a 2600 dinting machine, kept things moving underground from as early as 1993. „But even the most robust machine comes to the end of its useful service life one day. There was no question that we would replace it with the new SF 2600i dinting machine from Wirtgen, which has been providing excellent services here since November 2011,“ Hesser adds.

The SF 2600i is equipped with a cutting drum which levels off uneven surfaces to produce a perfectly even floor offering convenient riding properties and minimum rolling resistance. The salt mined in the Heilbronn mine has a compressive strength of between 20 and 25 MPa.

Operating at a working width of 2. 5 m and a cutting depth of 0.1 m, the SF 2600i achieves advance rates of up to 800 m per 8-hour shift. „This enables us to keep our road network in good shape all the time,“ commends the head foreman. After cutting, the material deposited behind the machine is levelled by graders, watered and compacted.

Hesser points out that „the dinting machine has been fully customized to meet our specific requirements. The close cooperation with Wirtgen - whether in terms of machine design, planning, transport, or after-sales service – was most convincing. And the benefits add up: our investment in the new machine pays off through increased efficiency as well as reduced operating and repair costs,“ says the expert, adding that „for us, the dinting machine is an indispensable asset.“

Milling under great deadline pressure has become normal, and speed of construction is an important factor of success for milling contractors. For precisely that reason, a Wirtgen cold milling machine type W 250 with 3.80 m wide, XXL-size milling drum unit has been part of the fleet operated by the milling experts from Kutter, who are based in the Southern German town of Memmingen, since the summer of 2011.

Milling instead of manoeuvring“With the 3.80 m wide drum installed in the W 250, we

significantly increase the machine’s milling performance as the drum is about 70% wider than that of the standard machine. As a result, turning and repositioning manoeuvres of the machine are also considerably reduced,” explains Roland Schmid, head of the milling division at Kutter. Bernd Holl, Product Manager Cold Milling at Wirtgen, adds: “The W 250 with 3.80 m wide milling drum efficiently translates the engine output of nearly 1,000 HP into milling power. In the United States, many of these XXL-size milling drum units have been in operation for quite a while. We are therefore all the more pleased that Kutter, our biggest customer in Germany, is now also using such a drum unit.”

Wirtgen offers the XXL-size milling drum units in several milling widths ranging from 2.50 m to 4.40 m. Kutter opted for the 3.80 m wide drum unit as “we can use it to mill off a typical German traffic lane in a single machine pass,” says Roland Schmid, adding that “the milling process is accelerated significantly when using the XXL-size machine. One reason is that there is less effort involved in coordinating operations as we need fewer machines.

WHEN A LARGE MILLING MACHINE OUTDOES ITSELF: WIRTGEN W 250 HIGH-PERFORMANCE MILLING MACHINE WITH XXL-SIZE DRUM UNIT

CLIENTS DEMAND MAXIMUM MILLING PERFORMANCE IN THE REHABILITATION OF MOTORWAYS, AIRPORTS AND OTHER LARGE TRAFFIC SURFACES. FOR JOBS LIKE THESE, WIRTGEN HAS DEVELOPED THE W 250 HIGH-PERFORMANCE MILLING MACHINE AND XXL-SIzE MILLING DRUM UNITS WITH MILLING WIDTHS OF UP TO 4.40 M. BAVARIAN CONTRACTOR KUTTER GMBH & CO. KG OPERATES ONE OF THESE EXTREMELY POWERFUL MACHINES, ACHIEVING TOP QUALITY AND MAXIMUM EFFICIENCY AT THE SAME TIME.

There and back – finished! Thanks to the 3.80 m wide milling drum unit installed in the W 250 from Wirtgen, Kutter was able to complete removal of the surface course on a Bavarian country road in record time.

34Issue 02 | 2012



In addition, we save time due to the reduced number of reversing manoeuvres. This pays off in time-critical night operations or on airport sites where time is limited.”

Ideal for surface course rehabilitation and milling in layers

The giant drum units achieve optimal results when milling off layers at depths of up to 10 cm, which makes them ideal candidates for the rehabilitation of surface courses. Milling in layers is therefore the most economical method when removing asphalt pavements at full depth. In addition, it is a fast-paced process; after all, the flagship machine from Wirtgen features an engine output of 731 kW. “When removing the surface course, the machine produces an excellent milling pattern at a milling depth of 4 cm and advance speeds of around 20 m/min. With a 2.20 m wide drum unit, comparable results can only be achieved at milling speeds of well over 30 m/min but this would have an adverse effect on the quality of the milled surface,” says Product Manager Bernd Holl.

This is confirmed by Kutter’s experience: when removing the surface course of a country road in the Bavarian town of Hofstetten, an impressive advance speed of 18 m/min was measured over a distance of just under 3 km. The

milling pattern and evenness produced were flawless despite the high advance speed, for the XXL-size milling machines achieve unrivalled levels of evenness due, in particular, to their tremendous milling width.

Easy handling, easy transportHandling of the XXL-size cold milling machines is

extremely straightforward. “Cameras give us an excellent view of the milling process,” says Klaus Strobl, milling machine operator in Kutter’s crew. And, as with all cold milling machines from Wirtgen, operation is exceptionally user-friendly. Finally, there is the question of how the wide machine gets to the milling site. Wirtgen offers an intelligent solution to facilitate transport: the WT 440 mounting carriage, which is used to transport the milling drum unit to the job site on a flatbed truck. When loaded with a 3.80 m wide milling drum unit, the carriage weighs around 20 tonnes, its width and height remaining below 3 m.

The machine minus drum unit has a transport weight of around 35 tonnes. For mounting, the self-propelled WT 440 is driven from the flatbed truck via remote control and is positioned underneath the machine. “Two of our staff need just under two hours to bolt the unit to the machine, connect it to the hydraulic system and install the power belt,” say the dispatchers at Kutter, relaying their experience. This solution provides them with a high level of flexibility in job site organization and machine scheduling.

Job descriptionIn the event of floods.,a dam of up to 6 m in height will in

future divert inflowing water into a landscaped detention basin near Tubingen in order to better protect the town from flooding. For this technically very demanding construction process, the contractor in charge relies on the Wirtgen WR 240/WR 240i recycler. Construction of the dam core by means of soil improvement is effected by back filling soil at a layer thickness of 50 cm and prespreading binder (50% lime / 50% cement). which is then homogeneously mixed in by the WR 240/WR 240i while adding water at the same time. In a final step.

The WR 240/WR 240i creates the water-tight dam surface by means of soil stabilization, mixing backfilled material with pre-spread binder (30% lime 170% cement) and water just as homogeneously at a depth of 50 cm. Specifications in terms of mix quality are high to ensure resistance of the dam against erosion and washout. To achieve this goal, precise adherence to the specified water content is of utmost importance.

Special advantagesThe state-of-the-art metering technology

installed in the WR 240/WR 240i meets highest demands in terms of precisely adhering to the specified water quantity. In addition, the actual water content is conveniently displayed on a screen.

JOB REPORT WR 240/WR 240I: PERFORMING TO HIGHEST qUALILTY STANDARDS

Layer upon layer, the WR 240/WR 240i homogeneously mixes the backfilled soil with pre-spread binder and water.

Excellent traction and off-road mobility thanks to the four-foldfull-floating system are the keys to success on heavy ground.

The project places high quality demands on the recycler‘s metering and mixing technology.

The water is provided by a tanker truck and is injected into the rotor housing in precisely metered quantities.

36Issue 02 | 2012



Optimal traction and large ground clearance enable the WR 240/WR 240i to make swift headway on the soft. clayey soil and also in the steeper sections of the terrain when creating the dam surface. Site conditions require a multitude of machines in operation, including dozers, excavators, tractors and spreaders. The outstanding manoeuvrability of the WR 240/WR 240i enables timesaving evasive moves, however, and reversing is additionally facilitated by the reversing camera with reverse assist.

Job descriptionAs forecasts anticipate high traffic volumes with

a correspondingly high percentage of heavy traffic, rehabilitation of the A7 motorway near Langenau calls for both a subgrade and upper pavement stnucture of superior bearing capacity, In order to meet these requirements, the WR 240/WR 240i is commissioned to produce a hydraulically bound base layer of high quality. In a first step, water and subbase binder (15 kg/m2) are distributed on the subgrade level previously produced by graders. In the following step, the WR 240/WR 240i thoroughly and accurately mixes the hydraulic binder into the existing gravel material at a working depth of 30 cm to produce a homogeneous mix. The WR 240/WR 240i stabilizes an area of 16,000 m² altogether, thus enabling the hydraulically bound base to be handed over to the subsequent project divisions on time.

The hydraulically bound base is characterized by perfect evenness, superior bearing capacity, water and frost resistance, all of which combine into a stable foundation for the new section of the A7 motorway.

Special advantagesThe WR 240/WR 240i impresses by paving the base

true to line and level as the automatic cross slope control prevents any displacement of material on the previously produced subgrade level. The machine‘s height adjustment makes quick work of constantly maintaining the working depth. The powerful milling and mixing rotor creates an excellent, homogenous mix of high quality so that the hydraulically bound base conforms to highest standards. The mixing concept with perfectly matched rotor and rotor housing produces mixes of superior quality in a short period of time, enabling the WR 240/WR 240i to stabilize at high advance rates. This results in economical operation and high daily output rates: in this project, the daily production of stabilized soil amounts to an impressive 10,000 m² (per 8-hour shift).

Following compaction, graders produce the finished grade level.

The WR 240/WR 240i stabilizes the base by thoroughly and homogeneously mixing the various components..

Streumaster spreaders distribute sub base binder in precisely metered quantities on the previously watered surface.

Water is distributed by special tanker trucks.

Job descriptionAs part of the new construction of an ICE line between Ebensfeld and

Erfurt, the surplus soil excavated during the production of line cuts and tunnels is transported to a nearby stockpile where it is stabilized by adding binders and then used to back fill bridge approaches, sewer trenches or similar along the railway line. Highest quality standards have been agreed on: in order to achieve a highly homogeneous mixing quality (grading curve < 25 mm). the client specifies thorough mixing in three machine passes.

In the first step, the WR 240/WR 240i therefore mixes pre-spread binder (up to 90 kg/m²) into the soil at a layer thickness of 50 cm to produce a homogeneous mix. In the second step, it thoroughly remixes the soil while adding precisely metered quantities of water. In the final step, the WR 240/WR 240i 110mogenizes the existing soil to make it suitable for placing. The quality of stockpile production is scrupulously monitored by an independent testing laboratory. In addition, restricted space conditions in the stockpile yard require frequent repositioning and reverse travels of the WR 240/WR 240i, as well as skilful working by the operator.

Special advantagesThe operator can control all important basic functions easily and

conveniently via the highly precise multifunctional joystick integrated in the right-hand armrest. Automated processes, such as automatic lowering and raising of the milling and mixing rotor, ergonomic workplace design and innovative reverse assist greatly increase operator comfort.

The rear axle features an extra large steering angle, allowing swift turning manoeuvres at the end of the short passages and in restricted space conditions. These advantages are reflected in improved operator performance. High engine power and optimal traction enable the WR 240/WR 240i to easily work its way through the heavy soil. The powerful, direct mixing rotor drive, rotor speeds adjustable from the operator‘s cab, and perfectly matched rotor bars ensure consistently perfect mixing quality - which is confirmed by every check performed by the testing laboratory.

In the first step, the WR 240tWR 240i mixes pre-spread binder into the back filled soil at a layer thickness of 50 cm.

Water is provided by a tanker truck and is injected int o the mixing chamber in metered quantities.

Final homogenization produces material of a fine-grained quality.

The high-quality end product is used to backfilltrenches or similar along the high-speed railway line.

Job descriptionAreas adjoining the noarby Main river need to be

stabilized as part of the new construction of an ICE high-speed railway line between Ebensfeld and Erfurt. Soft slate with a grain size of up to 350 mm resulting from a tunnel excavation is therefore transported to the relevant areas where it is heaped up by means of dozers and then pre-compacted and de-tensioned by means of Hamm earth compactors.

To produce grains of smaller size, Ihe extremely coarsegrained material is then homogeneously granulated by the WR 240/WR 240i at a milling depth of 50 cm and in a single machine pass. The surface is thus perfectly prepared for thorough re-compaction in a final step.

Special advantagesThe WR 240/WR 240i is the ideal candidate for this

truly tough job. Operating in difficult terrain, it granulates the material in a single pass thanks 10 its large working depth.

To be able to do so, a high-powered engine, powerful direct belt drive, impressive cutting performance and high advance rate are a „must“. The performance-optimized, heavy-duly rotor housing including rotor is crucial for producing the specified small-size material at a high advance rate. Even though granulation of the large chunks

of material creates high noise levels and strong vibrations, these disturbances are not felt in the soundproof, anti-vibration mounted operator‘s cabin. In his spacious, ergonomically designed cabin, the operator also remains undisturbed by high summer temperatures: an efficient automatic climate control system enables relaxed, productive working regardless of weather conditions.

Job descriptionThe WR 240/WR 240i carries out a soil stabilizing job on

a school playground in the Bavarian village of Frensdorf. Following pre-spreading of 37 kg/m² of binder, totaling 50 tons, on the 1.350 m² large area, the high-powered recycler homogeneously mixes in the lime-cement mixture at a working depth of 30 cm. Extremely restricted space conditions, existing fixtures. and building walls directly adjoining the job site make good manoeuvrability and an excellent view of the various obstacles an absolute must.The WR 240/WR 240i completes this assignment in next to no lime.

Special advantagesThe WR 240/WR 240i does an excellent job also on

this small job site, which is characterized by short lanes, reverse travels and turning manoeuvres in extremely cramped conditions. Being able to choose from three different steering modes offers an advantage, and additional steering of the rear wheels increases mobility even further.

Material with a grain size of up to 350 mm needs to be crushed at a depth of 50 cm in a single pass.

The operator always has a perfect view of both the milling edge and various obstacles like manhole covers.

On the job site. the WR 240/WR 240i achieves high daily output rates of up to 12,000 m².

In this job, the source material conSists of extremely coarse rock of poor quality and a grain size of up to 350 mm.

39Issue 02 | 2012



All actions required to perform the partly automated functions are realized intuitively via the multifunctional joystick integrated in the right-hand armrest. The individually adjustable comfort driver‘s seat and innovative visibility concept enable the operator to complete the entire job in an ergonomic seating position. A comprehensive camera system is the main feature of the visibility concept: four cameras, installed in optimal positions around the recycler, and the reverse assist allow important work situations to be displayed on two screens in the cabin.

A FIXED CRUSHER MOBILIZESFlying Change in The New Generation of Crushers

Already since 1992, Röhrig has been using a fixed jaw crusher Type C160 of Metso Minerals. At the beginning of this year, the enterprise has substituted the crusher with a further developed successor model of the same series. The so-called C-series of Metso that has been specially designed for pre-crushing of hard rocks easily tackles even the hardest feeding material. It was fortunate that the new fixed jaw crusher had identical measurements, so that is was possible to use the enclosure of the old crusher.

Marco Röhrig, the third generation leader of the enterprise, hopes that with some improvements in

The manufacturing base of the traditional Röhrig enterprise, which is mining granite in the third generation, is located in Heppenheim at the Bergstrasse. Röhrig’s „proximity to costumers“ is more than just about distances; one of its reasons being its above-average product variety. Due to its high innovation, the enterprise has established itself as a reliable material supplier for various branches of the industry, both regional, as well as international. Operational, as well as technical know-how of the enterprise is continuously updated in accordance with growing market requirements.

Repeat offender: 20 years ago Norbert Ried (fourth from left) has assembled the predecessor of the new C160, and he is happy about the endurance of the high-performance crusher, which makes room for the newer model.

The sidewalls of the new C160 are approximately 19% thicker; the hydraulic clamping cylinder is bigger in size and has higher performance. Metso has reinforced the transverse ribs of the wing, from 58 to 75 mm at the side, and from 66 to 100 mm in the inside. The integrated engine bracket, which in other models is outside of the crusher, was a fortunate fact, as Röhrig could use the enclosure without any reconstruction.

The C160 also scores with improvements in engine and balance wheel protection. Due its more robust construction, it needs fewer parts, making installation and maintenance easy. Accessing the motor is also significantly easier.

Under the leadership of the site supervisor Maik Engelstätter of Metso, dismantling and set-up could successfully be done within 2 weeks.

On the hook: After the old C160 was lifted by crane, the new crusher was quickly installed. In order to do so, only the top of the enclosure was disassembled.

Lateral protection: So-called Rockingham-dampers, a special development of Metso ensures a fixation of the plant without vibration in spatially limited conditions.

42Issue 02 | 2012



Flying Change:Installation in Enclosure

Marco Röhrig will certainly long remember the day of set-up. On that day, wings and crusher encasing were separately delivered and only assembled on site. The old crusher was exchanged within one hour. The 85 t heavy crusher was lifted by a truck-mounted crane into the crusher encasing exact to the milimeter. After positioning the new crusher into the existing steel construction, the plant had to be optimally fixed in the available constricted space. Here, special dampers, with a height of 2 meters prevent a sideway slide of the crusher from the carrier. The trial run with material was done approximately one week after the installation of all electrical cables.

Parallel to the installation of the C160 - the first of the newest generation in Germany-, Röhrig installed a new Metso cone crusher of the type GP100 in the high quality chipping plant. Marco Röhrig is expecting that the enterprise experiences global advantages through this technological improvement.

Röhrig places great emphasis on steady product quality, maximum added value and optimal processing of its product lines. Against the background that Röhrig has enough raw material reserves for the next 150 years, development with the motto of „quality instead of quantity“ can be continued without hesitation.

125 years of future According to the memoires of Carl Haver junior (1884

- 1976), which the son of the founder of the company, Carl Haver, wrote in the 1960s, “If someone had told my father in the early years of his entrepreneurial activity that his company would at some stage have branches abroad, he would probably have smiled in disbelief.” Together with his cousin, Eduard Boecker, he established the firm of HAVER & BOECKER on the 25th of August 1887 in Hohenlimburg, the German centre for wire drawing and wire weaving, at that time. Eduard Boecker left the company in 1891. The early years were difficult due to the working conditions in Hohenlimburg and the competition from Thuringia. This changed due to the move to Oelde in Westphalia, where the head office of the company has been since 1897. By 1890, the workforce had doubled from 12 to 24 employees. Apart from wire weaving, the engineering works established in 1925 had developed into the second mainstay of the company.

During the 125 year history of the company, the product range and production processes have been repeatedly coordinated in time with the needs and demands of the particular markets. Working as partners together with the customers, experience, continuous further development of products and production processes as well as the know-how and skill of its employees provides the main foundation for the success of the company. In addition, since the establishment of HAVER & BOECKER, the family, now in the fourth generation, has been actively involved in the management of the company. The legal status is still as a general partnership (oHG).

HAVER & BOECkER – 125 YEARS OF FUTURE :THIS MEDIUM-SIZED FAMILY-RUN COMPANY HAS BEEN SUCCESSFUL FOR 125 YEARS

The importance of education and further training was recognized very early on. Records show that training has been taking place since 1905. In 1940, an own trainee workshop was set up, and is currently equipped so that the industrial-technical trainees are able to develop and train their skills there. In a regional comparison, over 100 young people annually pass their technical or commercial vocational training at HAVER & BOECKER at an exceptionally high level and complete it with above average good final exam results. In 2007, the HAVER Academy was set up as a further education platform for employees and customers. Working together with Siemens vocational training and the South Westphalia University of Applied Sciences, it is also possible to train and study for a Bachelor of Arts or Engineering.

During the 125 years, the 12-man company in Hohenlimburg has developed into a diversified, internationally operating company. With a worldwide network of branches and factories, HAVER & BOECKER is currently active worldwide with 2,400 employees in all national and international markets as a technological leader and trendsetter. With its 50 subsidiaries worldwide, the company as a whole achieved a turnover in 2011 of more than 370 million euros.

An active corporate culture and the social responsibility of the traditional family-owned company towards the staff, customers and society, which far exceeds the statutory and contractual demands,

ATLAS COPCO LAUNCHES NEW MULTI-PURPOSE DRILLING RIG FOR TUNNELING AND MINING

New underground mine and tunnel expansion projects will hit production targets sooner, thanks to a new Atlas Copco Boomer E1 C-DH face drilling rig. The single-boom, diesel-

hydraulic multipurpose unit is specifically designed for mines or construction sites lacking water and electrical infrastructure. The Boomer E1 C-DH comes with dual onboard 450 liter water tanks and a six-cylinder, 173 kW (232 hp) Deutz diesel engine to drive the rig, its boom and the drill’s hydraulic pumps.


Multi-purpose drilling rig Boomer E1 C-DHThe new Boomer E1 C-DH rig is one of the largest diesel-

hydraulic face-drilling rigs on the market, with a coverage area of up to 95 square meters. This is a 38% improvement over its predecessor, the Boomer L1 C–DH drill rig .

According to Johan Jonsson, product manager for Atlas Copco Underground Rock Excavation, the new rig provides unique advantages in the field. “ In the case of a new project, the Atlas Copco Boomer E1 C-DH drill rig can be used to get started even before water and electricity are installed at the job site, ” he said. “Mines begin earning sooner, and contractors are able to get ahead on their schedules.”

Jonsson also pointed to the new drill rig’s advantages in widening existing tunnels or adding bolts in older workings, as it is not necessary to install power and water infrastructure to support the rig on-site.

The new drill rig also contributes to more economical use of a fleet’s resources. The Boomer E1 C-DH rig is able to handle small construction jobs more efficiently than larger rigs, and when used in a mine is compact and maneuverable enough to get the job done in tight spaces.

The multipurpose capabilities of the new rig are enhanced with the addition of the optional basket attachment. This allows the Boomer E1 C-DH rig to be used as a bolting rig and as a utility rig for drilling holes and installing ventilation ducting, among other tasks.

The Boomer E1 C-DH drill rig comes standard with Atlas Copco’s Rig Control System (RCS) with the option to upgrade to an even higher degree of automation. Jonsson said, “ As a member of the Atlas Copco Boomer E-series of face-drilling rigs, the new rig has access to the wide range of existing options for that established product family ,”

flexibility for long hole drilling applications.


The new Simba-quartettLong hole production drilling in mines can now

be substantially improved with the launch of new Simba drill rigs from Atlas Copco. The company has introduced four different versions of its Simba rig concept – Simba ME7 C, Simba E7 C (plus an ITH version) and Simba W7 C – thereby giving miners the widest possible choice of solutions for different mining environments.

The new rigs offer top-notch precision, versatility and flexibility but also provide mines with a much greater opportunity to adapt each unit to suit individual conditions and requirements. Thanks to their four stingers and the sturdiness and precision of their BUT 45 booms, the rigs also offer maximum safety during setup and positioning.

All four rigs are designed for long hole drilling (up to 51.2 m, theoretical depth) in medium to large drifts.

Simba ME7 C drills parallel holes spaced up to 6. 9 m • apart with a hole diameter of 51–89 mm.

Simba E7 C drills parallel holes spaced up to 6. 1 m apart • with a hole diameter of 89–127 mm.

Simba E7 C-ITH drills parallel holes up to 5.2 m apart with • a hole diameter of 92 – 178 mm.

NEW BUCkET CRUSHERS FROM ATLAS COPCO

Atlas Copco launches a range of four rig-mounted bucket crushers for efficient and economic recycling of all types of inert material on site. Asphalt, stone and concrete debris as well as mine

and quarry material can be crushed and directly re-used on site or sold to third parties.

AtlAS coPco conStruction toolS

Launch of four rig-mounted bucket crushers

Rig-mounted bucket crushers are an answer to the EU directive on waste management that demands a recycling quota of 70% for construction and demolition waste by year 2020. Atlas Copco bucket crushers reduce the mechanical equipment on site, as well as transportation and dumpsite cost. They can be employed at all urban worksites, especially in confined conditions.

Hydraulic bucket crushers from Atlas Copco offer a wide aperture bucket with large capacity. The output size can be easily adjusted from 20-120 mm (BC 1500: 20-100mm).

The range follows the strategy of lower cost of ownership which is common in all hydraulic attachments from Atlas Copco. Bucket crushers require low maintenance: a 30 hour greasing interval and only two grease points are the standard maintenance.

All crucial parts are long-lasting even under extreme stresses. The bucket jaws which take the most stresses, follow a clever wear part concept. They can be inverted, top and bottom jaws can be exchanged or single jaws can be rotated by 180 degrees to also use the rear part.

552 NEW BELL ADTS FOR HIGH-SPEED RAILWAY UPGRADE:

BELL’S LARGE TRUCkS PROVE BIGGER IS BETTER!

These groundbreaking additions to Bell Equipment’s already extensive ADT range and the company’s commitment to remain at the forefront of ADT design and technology has been acknowledged by the market with a steady growth in sales figures.

Managing Director of Bell Equipment France, Claude Boulet, reports that Bell’s large truck technology has been firmly established in Europe in recent years with over 60 units of B45Ds and B50Ds having been sold in France alone. Included in these figures are 27 B50Ds, which are to be delivered to Vinci Construction Terrassements for a challenging infrastructure project to extend the French LGV Network as well as 13 Bell B45Ds and 12 B30Ds to Razel/Bec, for the same project.

The French LGV Network (Lignes à grande vitesse) is one of the best developed high-speed railway systems worldwide with some 1 900 km of dedicated high-speed track. And it will be further extended when work starts this summer at the LGV Sud-Europe-Atlantique (SEA), linking Tours and Bordeaux, to form an important part of the future European High-speed Train Network.

The Articulated Dump Truck market has seen ambitiously launched 50-ton prototypes come and go as well as the upgrading of common 40-tonners by increasing capacity by a few extra tonnes.

However, it was Bell Equipment’s launch of the B50D at Intermat 2003, followed by the introduction of the B45D that finally established a new performance class within the 6x6 segment globally.

The 375 kW Vinci Bell B50D come with the 28-m³ standard bin equipped with liners.

The LGV SEA is a totally new section and includes 302 km of dedicated high-speed lines with 40 km of connection lines to the existing network. Accordingly massive earthmoving and ground engineering is required in the initial phases until 2014 when specific railway construction starts. Full operation is planned for 2017.

The project will cost an estimated 7 800 million Euro, financed on a public-private base, with 4 000 million Euro contributed by the state-owned French Railway Network RFF and official regional, national and European bodies and the contribution of the private sector to be refinanced over 50 years of operation. The concessionary body Ligne Sud Europe Atlantique (LISEA) contracted the consortium Construction Sud Europe Atlantique (COSEA) for the conception and construction activities. As in LISEA, the French VINCI Group plays the leading role in COSEA, being prominently involved with its specialist companies in the different project phases.

The initial infrastructure works is the responsibility of Vinci Construction Terrassements, co-operating with several other Vinci affiliates and French national or regional public engineering companies. Earthmoving and ground engineering works will start almost simultaneously to meet the ambitious time schedules.

In total 3 300 hectares – about 46 million cubic metres of earth – will be removed and another 30 million cubic metres will be refilled and reshaped. For these activities and infrastructure construction (bridges, underpasses, retention basins, etc.), the 300 km stretch was divided into 15 separate contracts.

Vinci Construction Terrassements will use its new fleet of 27 Bell B50Ds on five northern contracts between Tours and Poitiers. The company has an existing fleet of five, which it has operated since 2005, so the repeat business demonstrates the confidence the company has in Bell’s technology and the service performance of Bell Equipment France.

Bell ADTs are a popular choice on the project with earthmoving specialists Razel/Bec, belonging to Fayat Group, also making use of Bell trucks. Razel/Bec has been subcontracted by Vinci for three contracts on the southern part of the LBV stretch and signed an order in November 2011 for 13 Bell B45Ds and 12 B30Ds for this work.

“With this additional business, the whole LGV SEA project, Bell France has reached new heights. The specific challenges of the project in terms of massive volumes, narrow time schedules and difficult access to

The preheater tower of Lafarge Group‘s cement plant looms just a few hundred metres before the sign Wössingen, near Karlsruhe. In the seventies the plant has been taken over by the international producer of cement. “We have almost 78,000 employees in 78 countries“, says Stephan Schenk, Head of Servicing & Development at Lafarge Zement Wössingen GmbH. Worldwide, Lafarge is market leader in many countries, such as France, England, Poland, Greece and Austria. In Germany, Lafarge is among the six leading producers. “Thanks to the state-of-the-art technology and a high sense of responsibility, we produce approximately 800,000 tons cement per day for various applications and requirements at our Wössingen site“, explains Schenk. Lafarge

Spectacular residential and office buildings, tunnels and other infrastructure facilities – nothing can be built without cement. To produce cement for various applications in an economic way,

Lafarge modernised the production facilities at its plant in the town of Wössingen, in the Baden region, Germany. The modernisation included the existing belt bucket elevator to the raw mill. The intralogistics specialist BEUMER offered its innovative heavy-duty bucket elevators, permitting higher conveying capacity and longer service life. Thanks to this new technology, the existing bucket elevator could be easily altered.

places particular value on production methods that are both energy-efficient and environmentally sound. For this reason, the systems have been modernised for more than 60 million euros in 2008 and 2009. Now, the cement plant has a 5-stage heat exchanger and a new clinker cooler.

“We changed from the Lepol process to the energy-saving dry process with heat exchanger and precalciner with no interruption to the operation. To make the production more cost-effective and environmentally sound, we changed from the two-kiln operation to a single rotary kiln“, explains Schenk. “The kiln line has now a considerably higher capacity. The system is fed with approximate 150 tons of raw material per hour. Accordingly, the complete production has changed“, the engineers says. Due to the increase in performance and modernisation of the kiln line, the flow rate of the bucket elevator for the raw mill had to be increased considerably. The bucket elevator transports limestone to the mill bunker.

High wear of the belt “Due to the higher flow rates we had to face more

problems with the coarse-grained material“, remembers Schenk. Larger particles became repeatedly jammed between belt and bucket, causing substantial wear. Conventional belt bucket elevators are limited by the maximum grain size of the material to be conveyed as the conventional bucket mounting results in a gap of about 25 mm between bucket and belt. Larger particles may get stuck in this gap. This quickly results in belt damage when the belt runs around the return pulleys. “The belt became porous already after two years“, explains Schenk. A new solution needs to be found both to avoid belt cracks and

to meet the growing requirements. Nevertheless, long-term thinking was called for. “Because a new belt is very expensive“, adds Schenk.

New heavy-duty technology gets the job done

At first, the engineers from the Wössingen plant wanted to replace the existing belt bucket elevator with a central chain bucket elevator. “We would have solved the problem with the transport of coarse-grained material“, says Schenk, “but a new central chain bucket elevator would have become quite expensive.“ In search of a suitable solution, the cement producer contacted some manufacturers of vertical conveyors – among others, the BEUMER Group, headquartered in Beckum, Germany. The cooperation between BEUMER Group and the cement plant in Wössingen has a long tradition. For decades, the market leader has established itself successfully in this sector and could impress the customer with its solution. “When specifying our conditions, BEUMER recommended the newly developed technology“, remembers Schenk. “Central chain bucket elevators which transport limestone are subject to high wear as the raw material contains abrasive particles which act as sandpaper“, says Schenk. Though identical with that of belt bucket elevators if used for materials that have little abrasive action, the service life of chain bucket elevators is much shorter in the case of strongly abrasive materials. After thorough consultation with the BEUMER specialists only the belt and the buckets were renewed applying the new heavy-duty technology. This technology is used to feed material with particle sizes up to 120 mm and up to six percent moisture into the raw mill. “The capacity is now 800 tons per hour“, enthuses Schenk.

There is no more gap between belt and bucket. The result is that material cannot get caught anymore during the scooping and filling process.

64Issue 02 | 2012

NEWS & REPORTS


This is possible thanks to the new bucket geometry. There is no more gap between belt and bucket. Coarse-grained material do not jam during scooping and filling process. The buckets are mounted firmly to the back of the belt by segments and bolts. Belts with wire-free zones are used for the new heavy-duty bucket elevators just as with all BEUMER belt bucket elevators. The buckets can be fastened to the belt without damaging the steel wires or even cutting them. The traction forces of the bucket elevator belt are maintained to full extend. The new bucket shape also ensures smoother running and thus less noise. Depending on the material to be conveyed, BEUMER offers buckets which are adapted to the material or mounts a dynamic bottom into the bucket elevator boot. This prevents wet and sticky material in the bucket elevator boot. And if explosive material is to be conveyed, all components are available in ATEX version.

To convince the employees of Lafarge by the new technology, BEUMER invited Stephan Schenk and two of his colleagues to Beckum. “The new technology was demonstrated with a miniature bucket elevator. This hits the nail on the head“, he says with a smile. Demands that neither conventional belt bucket elevators nor central chain bucket elevators can meet. “BEUMER adapted the buckets to our specific requirements by using test material.“

A belt that resists high loadsWhile developing the heavy-duty bucket elevator,

the tensile strength of belts with wire-free zones was strengthened. The current belt has a tensile load of 2,500 N/mm, the new belt with wire-free zones has a tensile load of 3,300 N/mm. The conveyor belts are more resistant against mechanical wear, and they are able to transport coarse-grained material and have high tensile load, all this makes the new heavy-duty bucket elevator the favourite conveying system for strongly abrasive material with high capacity and large centre distance. “This belt has twice the service life of a chain. Bucket elevators fitted with this belt are a clear improvement over central chain bucket elevators when used for strongly abrasive material, such as clinker, ore or blast-furnace slag“, Schenk learned in Beckum.

The timeline was tight, just two months to plan and realise the modification. “We‘ve got the ball rolling in October. The date of delivery was at the beginning of January and the bucket elevator was operated at the end of February“, Schenk says. Employees of Lafarge carried out the assembly under the watchful eye of the BEUMER specialists. It was less for an undertaking for the cement plant. “BEUMER handled all the planning, we only had to mount the buckets and the belt.“

“This solution saved us a lot of money“, says Schenk. “The complete modification cost about 80,000 euros. In comparison, a new conventional belt would have cost 60,000 euros. If we assume that the BEUMER solution lasts twice as long, the modification would amortise after a short period of time“, stresses Schenk. “Even after six months of operation there are no signs of wear. This was quite different with the old belt.“

The new heavy-duty belts for heavy-duty bucket elevators can be designed with a tensile load of up to 3,300 N/mm.

ContiTech is increasingly relying on Chinese specialists and managers. This makes further integration in the country and market easier and ensures the loyalty of high-quality, skilled employees. After all, these are key factors in the long-term success of ContiTech. But with a high degree of fluctuation and competition for the best employees, China is not an easy labor market in which to operate. “This is why sustainable measures in both recruiting and long-term employee retention are of fundamental importance to us,” says Junsheng Liu. To ensure that employees stay with the company over the long term, ContiTech offers the best possible living and working environment for its employees: Its reputation as a secure, innovative, highly regarded and highly competent employer is testament to this.

Overview of the activities of the seven business units

All seven ContiTech business units are continually expanding their presence in the Chinese market:

Air Spring Systems: air springs for trains and commercial vehicles

Investment in the railway sector and China’s leading position on the global commercial vehicle manufacturing market provides excellent opportunities for ContiTech

Air Spring Systems. At its Changshu site, the company manufactures air springs for commercial vehicles and state-of-the-art air suspension systems for rail vehicles. It is also making major investments: In 2011, a new production facility was built for sleeve-type rolling lobe air springs for cab and seat suspension at a cost of nearly €1 million. Other production equipment was also installed for manufacturing commercial vehicle air springs and assembling railway vehicle systems. Further investments are already in the pipeline. The air suspension systems are featured in vehicles such as CRH 3 high-speed trains and Shanghai Metro trains. In the commercial vehicle sector, leading companies such as Zhengzhou Yutong Bus, Sinotruck and Dong Feng Lear rely on ContiTech’s technological expertise.

Benecke-kaliko: environmentally friendly surface materials

Chinese automotive manufacturers attach increasingly greater importance to interior trim materials that are particularly kind to the skin and the environment. That’s why ContiTech’s Benecke-Kaliko business unit has also been producing the Oeko-Tex-certified Acella® Eco Green cover material at the site of its joint venture Benecke Changshun Auto Trim (Zhangjiagang) Co. Ltd since 2011. Due to the high demand for its products, the company has expanded its local sales team and opened a new sales office in Changchun, about 2,000 km north of the plant in

Zhangjiagang. Clients in China include Yanfeng Visteon, FAW Volkswagen Automotive, Shanghai General Motors, Dong Feng Peugeot Citroën Automobiles, Ford, Shanghai Volkswagen Automotive, Shanghai Automotive Industry Corporation, Fiat and Johnson Controls. This year Benecke-Kaliko will be investing in a TPO extruder in Zhangjiagang, so the plant will feature the same product range as the plants in Germany.

Conveyor Belt Group: conveyor belt business expanded

With the acquisition of the conveyor belt operations of Tianjin Xinbinhai Conveyor Belt Co. Ltd. last year, the ContiTech Conveyor Belt Group yet again reinforced its commitment to the Chinese market and now locally manufactures conveyor belts for industrial applications as well. The Tianjin site, which manufactures products primarily for the metal and cement industries, power stations and handling facilities in ports, is to be expanded in 2012. At its plant in Changzhi, the company produces conveyor belts for mining applications, benefiting from its presence in the world’s largest mining industry market. Special-purpose conveyor belts are also assembled in Shanghai.

Elastomer Coatings: comprehensive expertise for offset printing

Business development in the Chinese printing industry is presenting huge opportunities for the ContiTech Elastomer Coatings business unit. In the Shanghai Service Center, CONTI-AIR® brand printing blankets are assembled and prepared for use in printing machines. The company is anticipating continued strong growth over the next few years thanks to customers’ ever more pressing

ecological demands. ContiTech is the first manufacturer to offer carbon-neutral printing blankets, thus making a contribution to reducing CO2.

Fluid Technology: know-how for hose components and line systems

ContiTech Fluid Technology is represented by three locations in China. This business unit supplies all kinds of connecting elements through which media such as fuel, coolant, oil or air flow – from hose components to complex line systems. Hose line systems for turbocharger lubrication and cooling as well as transmission oil cooling have also been produced in Changchun, the largest site, since 2011. Local OEMs in the emerging turbocharger business are thus provided with existing know-how. Since last year, the product range has been supplemented by air conditioning lines manufactured at the Shanghai site, where we want to expand our business with lines for the truck sector. The company also produces charge air, cooling water and heating hoses for the automotive industry at its Changshu location, which opened in 2010. The company’s customers in China include Great Wall Motor Company Limited, Beijing Automotive Group, Shanghai Automotive Industry Corporation, Beijing Benz Automotive, Dongfeng Motor, Shanghai Volkswagen, Fujian-Daimler, FAW-VW, FAW Car, BMW, Linde, Jungheinrich and Atlas Copco.

Power Transmission Group: drive belts for the automotive and industrial markets

The ContiTech Power Transmission Group is greatly expanding its Chinese production of drive belts for the automotive sector and other industries. In addition to timing belts for automotive original equipment, the business unit has also produced multiple v-ribbed belts and raw-edge v-belts for automotive and industrial applications at its Ninghai location since 2011. The company is seeking to establish an even more powerful presence on the market in 2012 by adding a further production line for v-ribbed belts manufactured in a forming process. It will then be possible to produce elastic v-ribbed belts locally as well. These belts make conventional tensioning systems redundant, thereby supporting the trend toward lightweight construction and making them very much in demand. Clients include all well-known automakers in China.

Mobility is the most important infrastructure challenge in urban centers • ContiTech Air Spring Systems in global demand as supplier for urban

transport solutions • Urban aerial ropeways help to solve traffic problems

contitech AG

Hanover, April 2012. According to the United Nations, more than half of the world’s population currently lives in urban centers and megacities where millions of people are out and about every day. The home and workplace are often a long way from each other – and as the population increases, so too do the challenges associated with freight and business traffic. Cities are growing so quickly that the infrastructure often cannot keep pace. Modern public transport is faced with huge challenges, because congested approach roads and city centers, constant traffic congestion and harmful emissions place a massive strain on humans, the environment and the infrastructure. What is needed are new urban mobility concepts and suitable innovative technology. “Whenever millions of people – or freight – frequently need to be transported locally or over long distances, air springs are an essential component,” says Hannes Friederichsen, head of the air suspension specialist ContiTech Air Spring Systems.

ContiTech Air Spring Systems has equipped the suburban trains operating in the Brazilian megacity of São Paulo with air spring systems.

NEW PATHS IN URBAN TRANSPORT

Air spring specialist in global demand for mobility solutions

Specialist technological expertise, huge product diversity and excellent material quality have helped to make the air spring systems developed by ContiTech Air Spring Systems one of the products of choice when it comes to suspension solutions for trucks, trailers, buses and rail vehicles. Air springs not only ensure optimum comfort, safety and quiet traffic, but also help to protect street surfaces. It is precisely in underground railways, commuter railways, local, regional and high-speed trains as well as buses that their benefits become readily apparent. This is why bus and rail transport manufacturers as well as urban transport operators around the globe rely on ContiTech. Underground railway passengers all over the world – from London, Paris, São Paulo and Rio de Janeiro to Sydney, Mexico City, Los Angeles and Washington – all travel on ContiTech air spring products.

71Issue 02 | 2012

NEWS & REPORTS


ContiTech Air Spring Systems is particularly well represented in China, where the buses produced by the leading bus manufacturer Yutong are all equipped with ContiTech air spring systems, as are nearly all of the eleven metro lines in Shanghai, which is home to 20 million people. Inter-city links are every bit as important for the functioning of larger urban centers too. Following the success of the Siemens high-speed trains VELARO China, which are equipped with ContiTech air springs, the company was awarded a contract to equip the latest generation of high-speed trains – the CRH 3 – which are built under license and operate on a number of routes including between Beijing and Shanghai.

ContiTech will also play a key role in transporting people en masse during one of the upcoming major sporting events: The 2014 Winter Olympics. Not only will passengers enjoy the benefits of ContiTech air springs when travelling in the trains operating on the high-speed route between Moscow and Sotschi, but Air Spring Systems will also be equipping one of the main aerial ropeways with its air springs. This is a key component of the traffic infrastructure for the Winter Olympics, which is expected to receive visitors numbering in the millions. “This huge international success is all thanks to our global site and service structure. From our eight plants in China, Germany, India, Korea, Mexico and Turkey, we serve key markets with high-quality, locally-made products. For us, this means that wherever in the world our help and expertise is needed, our employees are on hand almost instantly,” says Hannes Friederichsen.

Aerial ropeways as shuttles and complementary transportation

Aerial ropeways are more than just leisure and tourist attractions. It is precisely in urban centers that this energy-saving and environmentally friendly means of transport can offer a solution to numerous challenges in transportation. Aerial ropeways are often the only means of transport, particularly in areas where there is a lack of space or obstacles such as wide rivers or differences in elevation need to be overcome. As a result, more and more transport planners are starting to consider the use of aerial ropeways. To enable high transport capacities and, in turn, make aerial ropeways competitive in comparison with other means of transport, high-performance systems that can carry up to 8,000 people per hour are needed. One such system that offers sufficient capacity is the “3S Ropeway” from the aerial ropeway manufacturer Doppelmayr, which was successfully used for the first time in a European city at the 2011 National Garden Show in Koblenz. The aerial ropeway is designed with two carrier cables, which act as a single rail track, and a haulage rope. This ensures that passengers can sit in absolute comfort inside the cabin even during high winds. “Only this design, which involves high-performance ContiTech air springs, can ensure this. The air springs stabilize the cabins both vertically and horizontally because they are very light and, at the same time, can transport a high load capacity,” says Peter Luger, head of aerial ropeway development at Doppelmayr.

Mobility for megacities: Air spring systems from ContiTech stabilize the cabins both vertically and horizontally.

Nautilus Minerals Inc. to launch first subsea mineral resource project in Bismarck Sea • New development by ContiTech Oil & Marine • Collaborations with Houston-

based company Technip Offshore

contitech AG

Hanover, April 24, 2012. ContiTech has achieved another milestone: Its Fluid T echnology Oil & Marine segment has been commissioned by the Canadian company Nautilus Minerals Inc. to take part in the world‘s first deep-sea mineral resource project. The undertaking will see natural resources extracted from sulphide-rich deposits found on the ocean floor. Nautilus‘s Solwara 1 extraction project in the Bismarck Sea near Papua New Guinea will be equipped with high-tech hoses specially developed by ContiT ech to operate successfully in the extreme conditions found at depths of more than 1600 m.

In collaboration with Nautilus‘s contracted engineering partner T eChnip, ContiTech has engineered hoses that will manipulate and take up the often sharp-edged stones dredged up from the seabed by the remotely operated Seafloor Production Tools. In addition, ContiTech has developed a 155-metre riser transfer pipe that will connect to the long, rigid riser pipe to bring slurry from the sea floor up to the surface. A series of buoyancy units have also been created specially for this ambitious project. These will hold the hoses produced by Oil & Marine in an S-shaped arrangement under water and prevent them from sinking to the ocean floor as they bring natural resources up to the Production Support Vessel. Together, these elements will play a key part in the success of this project.

Explaining the choice of ContiTech and Technip as development partners, Nautilus Minerals Project Manager, Mike Howitt said: „For this pioneering project, we wanted

the support of specialists with significant expertise in offshore mineral extraction.“ The project is currently on track to commence production in late 2013. It will initially produce 1.2 million tonnes of material, with production ramping up 1.8 million tonnes in due course.

„This project is unique. We tested the durability of our hose at our Hungarian plant in Szeged under the toughest possible conditions for more than four months. During that time, we were able to prove that our highperformance hoses withstand not only outside pressures of up to 35 bars but also the environmental conditions at the site. Particularly important is the fact that we have managed to produce a lining for the hose that is extremely resistant to abrasion and very slow to wear down,“ says Peter Neale, President of ContiTech Beattie Corp. in Houston outlining the key requirements of the high-tech products. With only limited storage capacity available on the Production Support Vessel, the ho ses had to be designed with easy handling and storage in mind, wh ich presented a further consideration in terms of the hose design.

Massive sulphide deposits in the Bismarck Sea, on the edge of the Pacific Ocean off the coast of Papua New Guinea, were first discovered in 1996. Investments in the Solwara 1 project have totalled over US$400 million. Nautilus Materials has obtained rights to extract the minerals for 25 years and has appropriate approval from environmental authorities.

contitech AG

With its new series of advertisements, ContiTech AG, the global technology company from Hanover, is adopting an unusual approach to market communications. The focus of the advertisements visually is on hand-drawn images from the key industries for which the company produces sustainable products made of rubber and plastic, including the regenerative energy sector or sustainable mobility companies. Entertaining headlines help the reader quickly grasp the content of the application field depicted. At the same time, the ad conveys ContiTech‘s guiding principle – Engineering Green Value – by prominently featuring a green rubber tree leaf as a key visual. This stands for the special commitment and high degree of technological expertise involved in the sustainable development and use of ContiTech products.

Anja Graf, Vice President Communications and Marketing, explains the reasons behind this new type of ad layout: “With the flood of advertising messages, people hardly take notice of conventional advertising any more. They do, however, react strongly to simple stories, especially since such stories can present complex topics and abstract information in a simple manner. We want to present images and content that attract a great deal of attention, that you chuckle and talk about, since they are unusual and spark curiosity. They depict ContiTech as a company that adopts new approaches, is surprising and quite simply different.”

The images and text are supposed to be fun, so that the content and the central messages can be understood easily and intuitively. “The mental images that these ads evoke make it possible for us to tell ContiTech‘s stories in an entirely different manner. The spotlight is on our „green stories,” which are innovations from our business units for special tasks in our global society in which the focus is on the quality of human life: energy generation, energy efficiency, sustainable mobility or reliable supply,“ says Anja Graf. The central message is supplemented with a brief technical paragraph on the topic and the respective business unit.

kEESTRACk THE GREEN ELECTRIC ALTERNATIVE Keestrack introduces the new green electric alternative

for their

explorer range of classifiers named eCo-drive.

“This is not to ride on the ‘green’ wave”, says president Kees Hoogendoorn. “It has a lot of added value for the environment but also on the cost efficiency of the machine”.

The Explorer 1500 and 1800, both available as 3 and 4 split classifiers, are now also available in the ECO-drive version. The electrical driven machine can run autonomously by the diesel engine which generates the electric power. However the electricity can also be supplied by the electricity network or from an electrical plug on the crusher.

The screening results are the same as the standard diesel/hydraulic driven version however the maintenance costs of the ECO-drive diesel engine is much lower as this machine also runs on ‘external’ electricity coming from the power network or generated from the engine of a crusher placed before the classifier. This saves energy, money and reduces emissions.

The matching screen for every crusherWhat is less well-known is that for years Kleemann

has also been offering a large selection of mobile screen plants. „Screen plants are not as interesting as crushing plants from a technological point of view. This is why they are usually left in the background“, according to Markus Wörner, Head of Sales, Kleemann. „Nevertheless, they play a very important role in the preparation of mineral raw materials and that‘s why we offer such a large selection“, adds Wörner. Kleemann currently has no less than twelve different models of the Mobiscreen series in its product portfolio, with screening areas from 3.4 m2 up to 18.4 m2. There is thus the matching mobile screen for every mobile crusher plant in the Kleemann product range.

KLEEMANN IS RENOWNED FOR ITS INNOVATIVE AND HIGH-PERFORMANCE MOBILE CRUSHER PLANTS. BE IT IN THE MOST DIVERSE NATURAL STONE APPLICATIONS OR IN THE RECYCLING OF ASPHALT, CONCRETE OR MIXED RUBBLE, AT PRIMARY, SECONDARY OR TERTIARY CRUSHING STAGES, WITH ITS COMPREHENSIVE OFFER OF MOBILE IMPACT CRUSHERS, JAW CRUSHERS OR CONE CRUSHERS FOR YEARS KLEEMANN HAS BEEN SATISFYING DISCERNING AND PROFESSIONAL CUSTOMERS.

KleemAnn Gmbh

MOBILE SCREEN PLANTS FROM kLEEMANN: LARGE SELECTION, HIGH PERFORMANCE

Similar to the mobile crusher plants, Kleemann also makes a distinction here between plants for the contractor market, the so-called „Contractor Line“ and the „Quarry Line“, i.e. plants which are designed especially for the needs and conditions in the touch quarrying business..

Mobiscreen Contractor Line: The „all-rounder“

The Contractor Line screen plants can be used very flexibly, both with regard to the material to be screened, and to the operating location. Notwithstanding their high outputs, they can be easily transported and can thus also be used efficiently for smaller quantities. The smallest

plant is the Mobiscreen MS 12 Z. This double-deck screen plant, which is designed for coarse material, is extremely compact both as a grizzly and a classifying screen, and has a screening area of 1220 mm x 2750 mm (upper deck), making possible feed capacities of up to 200 tons per hour. The MS 13 Z and MS 15 Z models are also screen plants designed for coarse material and are equipped with two screening decks and with their larger screening areas cover higher output requirements of up to 400 tons per hour. The MS 14, MS 16 and MS 19 models are traditional classifying screens, which are available in a double-deck and triple-deck version (only MS 16 and MS 19). With screening areas from 4.2 m2 (MS 14 Z) up to 9.3 m2 (MS 19 Z or MS 19 D), material removal capacities of up to 500 tons per hour are possible.

Mobiscreen quarry Line: Robust and efficient for quarrying

The Quarry Line plants are primarily characterised by their extremely robust design, making them ideal for intensive and permanent use in the stone quarry. The plants are particularly interesting for linked machine combinations because, similar to the crushing plants in the Kleemann Quarry Line, they have diesel-electric drives. It is also quite practical to install an electrical interlocking device with upstream crushing plants. Two design concepts are also represented here. The MS 18 Z and the MS 20 Z are coarse screening plants and, just like their „smaller“ brothers and sisters in the Contractor Line, are well suited for the primary screening of coarse rock. However, when it comes to the screening of large quantities of small and

diminutive grain sizes, the only option is the triple-deck screening plants MS 20 D or MS 23 D. For example, the MS 23 D has a screening area of 18.4 m2 across the upper, mid and lower deck, and thus achieves total screening outputs of up to 800 tons per hour

Service from a single sourceIn addition to all the main advantages these plants

possess, huge importance is attached to another aspect: After-sales services.

mb S.P.A TRY ME, FEEL THE DIFFERENCE : THE NEW MB S.P.A. ADVERTISING CAMPAIGN

Hence comes the need for a new and bold image with a strong impact. A shouted message, a distinctive sign, a whirlwind of meanings and symbols. From this, comes the decision to once again place its trust in DDM Advertising, under the guidance of Creative Director Giorgio Canale, for the new 2012 worldwide advertising campaign.

The agency, following intense cooperation with MB S.p.A., has developed a strong, captivating image that is both unique and cutting-edge.

The protagonist is the statuesque Polish model Anna Stanczak, interpreting a blonde heroine with an icy stare, immortalised in images by the famous photographer Angelo Gigli.

The aim in clear: create a communicative concept that entirely plays on the ambitious pairing of the fascinating and supernatural world of superheroes with the flagship product of the company, the crusher bucket: small, light, manageable, yet powerful and indestructible, capable of crushing anything, even, and above all, unnecessary costs. This is the true “power of crushing”.

The heroine, wrapped in a long cloak in the typical company colour scheme, embodies its values: MB isn’t scared of competitors, skillfully pointed out in its claim, “TRY ME, FEEL THE DIFFERENCE”.

It is with this message that MB, ever distinguished for its cutting-edge and innovative machinery, wanted to make its world image more aggressive and competitive.

This choice of bold communication is not just limited to the campaign image, but comes across in a global restyling of the MB look, launched and officially presented at Intermat (Paris, 16th-21st April 2012).

The face of the superheroine will accompany all official events and become part of an integrated project of a much wider scope.

An integrated communication for a univocal message: superheroes have always had arch enemies, but in the end, they always come out on top.

MB S.P.A., THE VICENzA-BASED COMPANY FOUNDED IN 2001 IN BREGANzE AND ALREADY RECOGNISED AS WORLD LEADER IN THE PRODUCTION AND SALE OF CRUSHER BUCKETS,

HAS BEGUN 2012 WITH DESIGNS THAT ARE EXPECTED TO LEAVE A MARK.

THE COMPANY AT INTERMAT 2012: MB IN PARIS WITH TWO WORLD PREVIEWS

The Intermat tradeshow (Paris, 16th-21st April 2012), International Exhibition of Materials and Technology for the Construction Industry, was the ideal setting for the presentation of two new MB gems: the BF 150, with its 10 tonnes of weight and title of biggest bucket in the world, and the MB-L, the smallest crusher made by the company.

Suitable for diggers of 70 tonnes and upwards, the new BF 150.10 is the ideal product for those working in large quarries, as it is capable of great achievements in terms of productivity and efficiency.

For much smaller pieces of machinery on the other hand – buckets, mini buckets, backhoe loaders – the new MB-L is a true gem of efficiency and practicality: small, manageable and with a very high production yield, it is capable of crushing any type of material and of satisfying many MB customer needs.

The constant efforts for customer satisfaction, the continual improvement in results and a company policy geared towards 100% quality, are values MB S.p.A. has pursued from the very beginning. The innovative nature of its products, recognised on an international level also by the many awards received in different sector tradeshows, has become MB’s strong point, as the company continues at the same time to invest in marketing initiatives, tradeshows and communication campaigns.

The company is always striving to satisfy customer expectations by being on hand and by carefully listening to day to day customer on site problems, finding appropriate solutions to the different international situations in which MB S.p.A. operates. It is also thanks to this long-lasting relationship based on trust that MB succeeds in producing buckets that provide valuable support for its customers.

MB was at Intermat with four display areas: two outdoor (Paris demo B005 and A010) and two indoor (Hall 6, stand J074 and J012) to ensure coverage of the entire tradeshow floor and demonstrate the authority it has gained in the industry.

MB S.P.A., THE VICENzA-BASED COMPANY FOUNDED IN 2001 IN BREGANzE (ITALY) AND ALREADY RECOGNISED AS WORLD LEADER IN THE PRODUCTION AND SALE OF CRUSHER BUCKETS, HAS BEGUN 2012 WITH DESIGNS THAT ARE EXPECTED TO LEAVE THEIR MARK.

Whilst the outdoor areas allowed visitors to witness the work of the crusher giants and experience at first hand the great advantages these machines have on site and in quarries, inside the pavilion, MB continued the special shows and events started at Samoter 2011 with Burlesque, this time entertaining visitors with Pole Dance shows by Italian champion Valeria Bonalume.

VOLVO GROUP EXPANDS PARTNERSHIP WITH WWF!

Partnership with WWF The Worldwide Fund for Nature, WWF, is one of

the world’s largest and most respected environmental organizations, whose vision is to stop the degradation of the planet‘s natural environment and build a future in which humans live in harmony with nature. WWF’s Climate Savers program involves multinational companies in the battle to reduce carbon-dioxide emissions. These companies pledge to reduce their carbon-dioxide emissions pursuant to an agreement between the WWF and the company. The results will be reviewed by independent technical experts. The agreed target must be more ambitious than the company would have set on its own, and must also signify that the company is leading its sector in the reduction of greenhouse gas emissions.

In autumn 2010, the Volvo Group became the world’s first automotive manufacturer to join Climate Savers, in an agreement whereby the Group’s truck brands committed to reduce the total amount of CO2 emitted during the lifetime of trucks manufactured and sold from 2009 to 2014, by 13 million tons, compared to trucks manufactured in 2008. This

“BY EXPANDING THE PARTNERSHIP WITH THE WORLDWIDE FUND FOR NATURE TO INCLUDE OUR BUSES AND CONSTRUCTION EQUIPMENT, THE VOLVO GROUP DEMONSTRATES THAT IT IS SERIOUS ABOUT CONTINUOUSLY RAISING OUR TARGETS IN TERMS OF REDUCING CARBON-DIOXIDE EMISSIONS FROM OUR PRODUCTS, BY COMPLYING WITH OUR VISION FOR SUSTAINABLE AND CARBON-NEUTRAL FUTURE TRANSPORTATION,” SAYS VOLVO’S CEO OLOF PERSSON.

will be accomplished by launching the latest technology in fuel efficiency.

In the next step, starting January 1, 2012, Volvo Construction Equipment and Volvo Buses will be included in the agreement. Thanks to improved fuel efficiency, the total amount of CO2 emitted by trucks, construction equipment and buses manufactured within the Volvo Group through 2014, will be reduced by more than 30 million tons, compared to vehicles manufactured in 2008. 30 million tons is the equivalent of the total carbon dioxide emitted by Sweden in a seven month period.

The Volvo Group works continuously to reduce carbon-dioxide emissions from products and production units, an effort that includes technologies for enhancing fuel efficiency and finding alternative fuels. Major resources are spent on developing such alternative drivelines as hybrid solutions and engines that are optimized for renewable fuels.

The agreement between Volvo and WWF applies for AB Volvo and the Volvo Group’s brands Volvo Construction Equipment, Volvo Buses, Volvo Trucks, Mack Trucks, Renault Trucks, UD Trucks and SDLG. SDLG manufactures construction equipment in China, and will be the first Chinese company ever to join Climate Savers.

The agreement between Volvo and WWF also states that:

Volvo will develop a new truck prototype with 20% • lower fuel consumption than a corresponding truck manufactured in 2008.

Prior to 2014, Volvo will offer the commercial • market trucks that operate on renewable gas.

The Volvo Group will also reduce CO2 emissions • from its production plants by 0.2 million tons (12%) before 2014, compared with 2008.

VOLVO CONSTRUCTION EqUIPMENT GRADERS WITH OVER 130 YEARS OF EXPERIENCE

With over 130 years of experience, Volvo motor graders are engineered with field-proven components for reliable service life. It’s the road grader versatility that makes it unique in

earthmoving, road building, snow clearing, ripping, scarifying, plowing and pushing.

Motor grader G900B

From fine grading in the creep mode to high speed applications or heavy earth carving to the all-wheel drive operation; it is the machine productivity that always makes the grade. Get Volvo motor graders and get the job done, every day.

86Issue 02 | 2012

NEWS & REPORTS


TOP FEATURES FOR THE RANGE OF VOLVO MOTOR GRADERS INCLUDE:

3 power settings with 8F/4R transmission or 8 power settings with optional 11F/6R transmission:

Volvo’s D8 / Tier 4i engine features increased displacement, power and torque. Engine characteristics are perfectly matched to Volvo transmissions, maintaining legendary Volvo grader productivity in the most demanding applications. Three or eight power settings automatically deliver optimum power in each gear for reduced wheel slippage and fuel consumption.

Volvo AWD (All Wheel Drive) system: Built around two variable displacement hydraulic

pumps and direct drive wheel motors. The system provides additional blade pull of up to 3 855 kg (8,500 lb) and greater front-end stability under low traction conditions like snow and ice.

Volvo ROPS/FOPS Care Cab Volvo is committed to making operators’ jobs easier

and more productive. Cabs include plenty of glass for unobstructed views; easy-to-use ergonomic controls; a familiar steering wheel; comfortable seating and a Contronics system to keep operators informed of all functions in real time.

Twin gear circle turn system Volvo’s exclusive circle turn system uses twin gear,

direct-acting hydraulic cylinders that provide instant, high output torque, enabling moldboard rotation under any load. This means there is no need to stop, reverse and change moldboard angle.

Lifetime frame warranty Volvo exclusively offers an optional first user Lifetime

Warranty on the front and rear frame, as well as on the articulation hinge and bearings. Provides even more peace of mind for owners

Volvo Graders Save $37,000„We had Caterpillar graders when I started here 12

years ago, and then in 2004 we looked at the possibility of getting Volvo graders,“ says Capps. „We tried them, and we liked the product. We presented the idea to the county commissioners, and they approved.“

The acquisition process was not a problem, because Volvo had won the statewide county bid for that class of motor graders. „We bought eight Volvo 720B graders,“ said Capps. „After a year, we turned them all over and bought nine new Volvo G940 graders, which have since been turned over for new Volvo graders. We like to run newer equipment, and we like to stay within warranty if we can.“

Operating costs confirm the county‘s decision to go with Volvo. „Compared to other brands, the Volvo is a good value,“ says Capps. „Depending on the application, we burn between four and five gallons of fuel per hour in the Volvo graders. That‘s a savings of about two gallons per hour, compared to non-Volvo machines. If you add that up over a year, running eight graders, that‘s $37,000. That‘s a significant amount of money to us.“

Hard-Working MachinesThe eight Volvo G940 motor graders are real workhorses

for Covington County. „They maintain our 670 miles of unpaved roads,“ says Capps. „We use them to pull, or cut new ditches on dirt roads, and to do the grading required for chip seal roads. Recently we‘ve probably built 10 different chip seal roads on dirt, ranging from 800 feet to 3 miles in length.“

The county also uses its motor graders to „clip the shoulders“ on paved roads. On those, soil and trash can build up at the edge of pavement, and the shoulder must be cut down level to the pavement.

But the lion‘s share of work for the motor graders consists of pulling ditches on the dirt roads. In the northern part of the county, the dirt roads consist mainly of clay. The clay roads are more stable and the ditches don‘t need to be cut as often as in the southern half of the county, where the soil is sandy. The sandy roads need their ditches pulled every year. „We probably pull ditches every year on three-quarters of our 670 miles of unpaved roads,“ says Capps.

Pine straw frequently gathers in the ditches and must be graded up onto the roads in the first pass with a grader.

87Issue 02 | 2012

NEWS & REPORTS


On the next pass, the grader will cut deeper, pulling soil up onto the pine straw and burying it. „If you don‘t bury that straw, it will wash-board the road - create bumps in it,“ says Capps.

Getting Maximum TractionMike Hughes, the road superintendent for the

southern part of the county, says he likes the variable horsepower feature of Volvo motor graders. „You can get moving better from the start and as your load increases, you can apply more horsepower,“ says Hughes.

A motor grader is traction-limited at low speeds, explains Gary Atkinson, regional product manager for Road Products, Volvo Construction Equipment. „You can only take advantage of as much horsepower as you have weight in the machine,“ he says. „So you limit the horsepower at lower speeds and in the higher gears you increase the horsepower. That way you reduce tire wear - you‘re not slipping - and you don‘t waste horsepower that you can‘t use efficiently.“

What‘s more, Volvo engines deliver higher torque at lower engine speeds, says Atkinson. „You can run at a higher gear with lower rpm‘s, which produces less noise, less fuel consumption, and longer engine life,“ says Atkinson. The Volvo G940 graders have 11 gears forward and six gears in reverse.

Operator Chris Nelson says he likes the memory gear feature on the Volvo G940. When shifting back and forth between forward and reverse, the grader will remember what forward gear the operator selected and which reverse gear he selected. „If I‘m finish grading something in first or second gear forward, then I‘ll back up in fifth or sixth gear reverse,“ says Nelson. „The grader remembers what gears I‘m using, and I don‘t have to shift through all of the gears every time.“

Getting Good GradesEach year the state of Alabama rates the county‘s

paved roads on a 100-point scale, with 100 being perfect. A number of factors enter into the rating process, including surface condition of the roads, the edging, the clarity of the centerline stripe, the ditching and more.

In recent years, says Capps, he and his team of 56 employees in the Road Department have succeeded in raising Covington County‘s rating from 79 to 93. „How did that happen?“ we asked Capps.

Five years ago, the county performed a $4.3 million resurfacing project that helped upgrade the paved roads. And the county bought a pavement-striping machine that helps keep the centerline stripes in good shape. The Volvo motor graders clip the shoulders on paved roads, so they have helped. „It‘s just managing your roads,“ says a modest Capps.

Minimum DowntimeCapps says the county seldom has any downtime

with the Volvo motor graders. And if something goes wrong, ASC Construction Equipment - the county‘s Volvo dealer - is right there to fix the problem. „If we do have a problem we can call ASC and they respond quickly,“ says Capps. „Often they have fixed a problem early in the morning, even before the operator gets to work. That means a lot - when you don‘t have an operator waiting on service to go to work in the morning.“

In fact, says John Edwards, ASC‘s general manager for the Gulf Coast, the success of Covington County‘s grading operations is a direct result of cooperation between Volvo, ASC, and the county. „All three of us work together to produce some of the highest-quality roads - for the lowest possible operating costs - in the state of Alabama,“ says Edwards.

The new monitor allows managing the standard rear-view camera via quick-access buttons, as well managing two optional cameras.

The attachment quick coupler also is controlled from the monitor, and an audible signal informs the operator that the coupler is open. The coupler is controlled with a new valve that provides the same operating sequence as that for 300D/E tracked machines. The travel-lock function also is now accessible through a quick-access button on the monitor and is standard on all cabs.

A new right-hand switch-panel module, again the same as that used on six-cylinder wheeled excavator machines, now houses the rotary-throttle dial, allowing the operator intuitive access to engine-speed control. The rotating beacon‘s switch also is located on the new panel - a small change, but reflective of the attention to detail in the refinement of these models.

Seat refinement includes a lumbar-support feature for the mechanically suspended seat, and a new low-frequency, air-suspended Comfort seat that features lumbar support, lockable horizontal suspension, mechanical height adjustment and passive climate control. The latter feature allows the seat to wick moisture away from the surface of the seat cushion with a carbon-fiber layer positioned between the fabric and the seat foam. The wicking system then allows moisture to escape when the seat is unoccupied. The result is a continually dry seat that adds to overall operator comfort.

technical refinement, fleet management, serviceability

New features to facilitate easy maintenance include rerouted coolant lines for unhindered access to service points and an easy-to-use shunt tank with redesigned filler neck and cap. In addition, new electrical connectors are used for the proportional pilot valves, and the hydraulic tank incorporates new pressure and temperature sensors, as well as a new drain valve.

The M313D and M315D can be equipped with the Cat Product Link system, which is deeply integrated into machine systems to allow remote monitoring of such data as location, event codes, diagnostic codes, hours, fuel usage and idle time, as well as allowing mapping functions, such as geo-fencing. Using a powerful telemetric system, Cat Product Link transmits this information to the customer and the dealer via a secure, web-based application, VisionLink™.

The Cat Machine Security System (MSS) is another asset-management tool available for the new excavators (standard in North America and EU). The MSS, which uses special keys with an electronic chip, controls who can operate the machine (and when). The MSS, using a small antenna around the key switch to read the user‘s identity, then checks if the operator is authorized.

three East-bound and three West-bound lanes. The new lanes will be placed in an existing median, and a central concrete barrier installed for safety.

Section 19 includes the main access point to Gauteng’s West Rand region, which flows to the agricultural and mining heartland of Mpumalanga province. Managing high traffic densities as the roads are realigned is among the challenges.

The durability of the well-travelled road starts with the creation of the base. The N12 design calls for an emulsion and cement stabilisation mix for the sub-base layers. That work is already under way.

“What makes the N12 project particularly noteworthy is that all materials will be worked in-situ or sourced from cuttings that will make way for the new lanes and interchanges along the route,” explained Raubex

Construction’s Johan van der Merwe. “Achieving this requires very complex planning to meet incremental timeframes.”

Some 74 earthmoving machines will be deployed on the N12 site at some time during the project, a high percentage of which are Cat® machines supplied and supported by southern African Cat Dealer, Barloworld Equipment.

The role of the reclaimerA new Cat RM500 Rotary Mixer was an early contributor

on the jobsite. The machine handled full-depth reclamation and soil stabilisation for both the new and existing lanes.

Raubex was familiar with Cat rotary mixers. The firm gained considerable experience with the smaller-sized RM300, one of which worked on an earlier portion of the freeway system.

Barloworld Equipment’s product manager, Johan Hartman, explained that the Cat RM500 has an operating weight of 28,145 kg and is driven by a Cat C15 ACERT™ engine generating a gross power output of 403 kW. This

compares with the Cat RM300 operating weight of 24,454 kg and gross power delivery of 261 kW via its Cat C11 engine. Width of cut on both models is the same at 2,438 mm, while the maximum cutting depth is 457 mm.

Dual-pump systemUnlike the RM300 unit, which has a single water pump

for optimum moisture content delivery, the RM500 design incorporates both a water and an emulsion pump that are simultaneously monitored in the cab via two separate flow meters.

“We needed a higher power-to-weight ratio on the N12 to cope with the existing varied in-situ premix materials, plus the dual mix stabilisation design makes the RM500 the optimal choice,” van der Merwe said.

The RM500 pushed two tankers, one carrying 18,000 litres of emulsion and the other 18,000 litres of water for the sub-base phase. The emulsion ratio was between 2-3% and cement around 1.5-2%.

The RM500 water spray pump system has two flow-rate ranges, extending from 114 to 1,836 litres per minute, with the emulsion spray pump system operating at predetermined volumes of 114 to 757 litres per minute. With the RM500, Raubex was able to reclaim and stabilise the 300 mm sub-base in one pass.

The equipment team on the ETB section will comprise the Cat RM500, the latest generation Cat 140K motor grader, plus Cat CS76 single drum 20-tonne vibratory rollers.

Rotor and the sub-baseIn the 300 mm sub-base layer, the RM500’s universal rotor

- equipped with its 200 carbide-tipped bits arranged in a chevron pattern - came into play in reworking these dense in-situ materials, providing the highest level of material pulverisation and gradation. A three-position mode switch enabled the rotor depth to be controlled manually or automatically to a preset cutting depth to ensure that the engineering design was precisely met. Most often on the job the machine cut at a depth of 45 cm, including a 7 cm asphalt surface.

The RM500 mixing chamber features a heavy-duty hood with a large volume capacity to handle deep mixing. This ensures exact depth control, proper sizing and thorough blending of reclaimed materials.

The production requirements on Section 19 are substantial. Raubex’s RM500 was deployed for the sub-base component, amounting to 135,000m³, while the selected 300 mm layer comprised some 102,000m³.

Additionally, the new highway construction will require some 9 million litres of emulsion, 5,000 tonnes of cement, 114,000 tonnes of BTB, plus 530,000m² of 35 mm AE2 asphalt premix and the equivalent for the 18 mm ultra-thin friction course (UTFC) overlay for the final riding surface. Black-topping will be carried out by Raubex Limited division, Roadmac Surfacing.

The purchase of sub-grade materials from the crushing plant was not required because the machine was able to turn the reclaimed gravel into sub-base material.

“Logistical planning is the key, as is the optimal deployment and utilisation of our earthmoving fleet,” explained van der Merwe. “In this respect one of the features we particularly like about the RM500 is its flexibility and all-round viewpoints to the front and rear. The ability to hydraulically shift the entire cab from side-to-side, for example, really speeds up the work rate as there’s no need

to plan in half-widths, plus the mix is always visible from the operator station.”

This full width side-to-side feature enabled the operator to work up and down specific stabilisation sections without having to reverse back to the starting point of the works, maximising on-site productivity.

Completing the transformation“Efficient use of materials and machines will be

interdependent on this contract and we have invested in the best possible technologies to meet our completion targets as we steadily transform Section 19 into a multi-lane world-class highway,” van der Merwe added.

The new modular C&D waste recycling plant from CDE Global

The site will be open to visitors from 3rd to 5th July 2012 and the company expects significant interest from the construction materials and recycling industries in the UK and beyond. “Early interest in the demonstration events indicate that as well as existing customers and others from the recycling industry in the UK there will be many international visitors over the three days” says Helen Ryan, Marketing Manager with The Malcolm Group.

The event is being hosted to demonstrate the new modular C&D waste recycling plant recently purchased from CDE Global. The washing plant includes an M2500 E4R mobile aggregate and sand washing system, Aggmax 83R portable logwasher, aggregate screening and trash removal plant and a water management and recycling system, the Aquacycle A400.

MALCOLM CONSTRUCTION TO HOST C&D RECYCLING PLANT OPEN WEEk

Malcolm Construction are hosting a three day event at their Shewalton quarry & Waste Management facility in Irvine on the west coast of Scotland allowing visitors to view a demonstration of the new C&D waste recycling plant installed at the site.

cDe GlobAl ltD

The plant is being used to process a variety of wastes including arisings from Malcolm Construction public works contracts and construction, demolition and excavation waste received at the landfill sites operated by the company. The processing of this material results in a recycled sand product with application in concrete and a clean recycled aggregate. “There has been significant interest in the recycled concrete sand from some of the major players in the Scottish construction materials market” explains David Balmer, Environmental Manager with Malcolm Construction. “The recycled aggregates have shown significant quality improvements from dry processed material thanks to the removal of lightweight contaminants by the Aggmax.”

Material is first delivered to the M2500 and an overband magnet on the feed conveyor removes any ferrous material which is subsequently discharged to a skip. A wash box at the head of the feed conveyor fluidises the material before it is delivered to the integrated Prograde P275 double deck rinsing screen.

98Issue 02 | 2012

NEWS & REPORTS


The 5m x 1.5m screen is fitted with wire mesh on the top deck with a 40mm aperture which delivers the +40mm material to the oversize stockpile via one of the four integrated 9m stockpile conveyors. This material is then crushed before being sent back to the M2500 for further classification.

One of the major benefits of the Prograde screen is the independent washing system which ensures it is entirely separated from the vibration of the screen minimising the risk of plant failure. “This is a unique feature of the Prograde rinsing screen in that it has been designed with washing in mind” explains Eunan Kelly, Regional Sales Manager in Scotland for CDE Global.

The lower deck of the Prograde screen is fitted with polyurethane screen media (5mm aperture) and the 5-40mm material is then sent to the Aggmax 83R. This unit integrates several processing phases including attrition, trash removal, dewatering and sizing of the clean recycled aggregate.

As material enters the integrated Rotomax RX80R logwasher attrition is applied through synchronised rotation of the dual shafts which are fitted with highly wear resistant high cast chrome paddles mounted in a fan arrangement. This arrangement not only ensures that the material in the Rotomax is subject to the highest level of attrition but also eliminates shock loading on the bearings thus reducing plant maintenance requirements. Efficient synchronisation of the dual shafts is achieved by the drive mechanism with a single motor and gearbox. “The Rotomax is designed to deliver on all fronts – maximum attrition for the material to produce the cleanest aggregates possible with additional steps taken to maximise wear resistance and reduce the on-going operational costs of running the Rotomax” explains Eunan Kelly.

As the recycled aggregate moves through the Rotomax the liberated fines, waste water and lightweight contaminants are floated off at the rear and delivered to a trash screen. Efficiency at this stage is maintained through the steep waste discharge chutes which eliminate the risk of blockages by the recovered sand product. The trash screen allows for the liberated fines to be sent to the sand washing phase while the lightweight contaminants are discharged into a bay.

Once the aggregates have progressed through the Rotomax logwasher they are discharged to the dewatering and sizing phase. In this instance a triple deck dewatering screen is employed to allow for the production of a 5-10mm, 10-20mm and +20mm recycled aggregate which are sent to stockpile via three 15m mobile conveyors.

The configuration of this dewatering and sizing phase can be altered with the option of single deck, double deck or triple deck screen. The option chosen will depend on a variety of factors including the aggregate specifications required and existing equipment available on-site. “If there is an existing mobile dry sizing screen on-site this can be employed at this stage allowing for specification of the single deck dewatering screen on the Aggmax” explains Eunan Kelly. “The advantage of the two or three deck screen is that it can save considerable space on site by removing the requirement for an additional dry sizing screen.”

The -5mm material liberated from the 5-40mm fraction is sent back to the Evowash sand washing plant integrated on the M2500. This is combined with the -5mm fraction from the initial screening phase which is delivered from the Prograde sump to the Evowash dewatering screen which is split to allow production of two sands.

A 0-5mm sand is dewatered and stockpiled while the 0-2mm material is collected in the Evowash sump and pumped to the hydrocyclone. The -63micron fraction is removed along with the waste water via the cyclone overflow and is sent to the water treatment phase. Meanwhile the fine sand fraction is discharged via the cyclone underflow onto the second side of the split Evowash screen before being dewatered and stockpiled. “Demand for the recycled sand product has been considerable since the new washing plant has been commissioned as a result of the quality of the material” says David Balmer of Malcolm Construction.

Waste water containing the -63 micron material is sent from the Evowash to the Aquacycle thickener by means of a gravity feed. This water recycling phase involves dosing the material with a flocculent which is prepared in the FlocStation poly plant. This is housed in an insulated 6m cabin alongside the full wash plant control panel.

The flocculent forces the fine particles to bind together and sink to the bottom of the Aquacycle tank where the settled sludge is conditioned by the quadrake mechanism. This ensures that the sludge density is optimised for discharge from the Aquacycle and allows the sludge to be pumped much greater distances than would otherwise be the case.

As the sludge settles, the recycled water overflows the weir at the perimeter of the Aquacycle tank and is then re-circulated around the washing plant which reduces the volume of fresh water required to feed the plant by 90%.

In this project, as on all C&D waste recycling plants which include an Aquacycle thickener, an additional

lightweights removal screen is included over the Aquastore tank to ensure that lightweights such as polystyrene to not make it back into the water circuit preventing downstream issues with water pumps becoming blocked.

Visitors to the Malcolm Construction site at Shewalton Quarry will have the opportunity to inspect the new washing plant accompanied by members of the CDE team. Malcolm Construction will also have a team of people available to answer questions on their experience with the new plant. “Our investment in this new plant demonstrates our commitment to reduce the volume of waste going to landfill and to maximise the recycling and recovery of materials for re-use” says David Balmer. “We look forward to welcoming our customers and other visitors to the site in July.”

SILA SANON qUARRYADOPT MOBILE SOLUTIONS

TO SATISFY GROWING THAI AGGREGATES DEMAND

SAnDViK conStruction, thAilAnD limiteD

Situated just over 100km north of Bangkok, Silasanon Quarry is located in Thailand’s Saraburi province. Operational now for almost thirty years, it was established in 1983 by the father and grandfather of the current owners, Chayuth Busitarnuntakul and Bhisanu Busitarnuntakul. The family now owns and manages some of the biggest quarry operations in Saraburi province, with Sila Sanon being just one of twelve quarries in the area. However, it was the Sila Sanon quarry that was identified as requiring investment in order to fully take advantage of the limestone deposits to be found. The materials present are required by the rapidly growing Thai construction and minerals industries that possesses an almost insatiable demand for high grade limestone. To this end Messrs Busitarnuntakul realised that if they were to satisfy market demand for high quality, accurately sized products, then they needed to invest in modern, highly productive crushing and screening systems.

The father and son Busitarnuntakul team realised that an investment of the magnitude required necessitated taking expert advice from screening and crushing professionals who would be able to offer first class guidance regarding the very latest developments in screening and crushing technology. Thus, they had no hesitation in contacting the William Wong Group, who not only possess an excellent reputation for service and aftermarket care, but as Sandvik Construction’s dealer in Thailand are able to draw upon Sandvik’s extensive minerals processing experience and know-how.

Having discussed their options with both the William Wong Group and Sandvik specialists, Chayuth and Bhisanu Busitarnuntakul realised that in order to maximise the materials within the Sila Sanon quarry a combination of stationary, as well as mobile crushing and screening equipment would be required. The following

The Sandvik range of tracked impact crushers have been designed to provide customers with extensive mobile crushing solution whatever the material application. All Sandvik models possess high reduction ratios giving customers the best possible product shape, high productivity, low wear, easy maintenance and a low cost per ton. They are available in heavy duty and compact formats, and possess options to suit virtually all customer requirements.

Although the QI340 tracked impactors are capable of producing an excellently shaped accurately sized product on their own, the Sandvik screening and scalping systems are able to further grade the limestone based on the specific requirements of the customer. This latter point is particularly pertinent as the limestone from the Silasanon quarry is used in a variety of applications ranging from

ready mix concrete plants, road contracting, generic construction, as well as being supplied to the industrial / chemical manufacturing industries for use as quick lime. Being able to offer their customers a flexible and highly productive service has been an essential component of the success of the Silasanon quarrying operation, and this is perfectly illustrated by the fact that one of their major customers is the Siam Cement Group (SCG) - the biggest ready mix supplier in Thailand.

Sila Sanon Quarry now produces more than 200,000 tons of various sized products each month, with approximately 80,000 tons of coming from the mobile plant alone. Due to the success of the new Sandvik mobile crushing and screening operation plans are now in place for over 50% of materials produced on a monthly basis to be derived from mobile crushing plant. This is due to the inherent flexibility of the mobile systems that are able to go exactly where they are required (the Silasanon quarry face is now 2km from its initial location in 1983), feed directly to transportation systems, and still deliver high quality products at high rates of production.

Operations at their Sila Sanon quarry have shown Chayuth and Bhisanu Busitarnuntakul that Sandvik mobile technology, combined with first class local representation through the William Wong Group, has enabled them to save on transport costs, process materials directly at the quarry face and at the same time use non-specialized transport equipment. The inherent flexibility of Sandvik mobile crushing and screening equipment has enabled all of these things to be achieved, whilst being able to deliver high quality limestone products at impressive rates of production that is able to satisfy customer demand.

Major Order from RussiaThe term “stowage“ comes from mining and refers to

the staggered arrangement of the pits in underground mining. To avoid that these pits choke after mining, they are re-filled with concrete produced in the grinding-mixing plant.

In the mineral processing plant, dolomite is crushed from 0/1000 mm to a grain size of 0/20 mm and classified. The crushed dolomite (0/20 mm) is fed to the two ball mills and ground and mixed to approximately 0/2 mm by adding cement and water. The concrete mixture from the overflow ball mill comes to the stowage complex via a storage tank and pumps.

From the cement unloading station, cement is pumped into the silo works and then from this silo works into the intermediate silo of the grinding-mixing plant. Thanks to the integrated lorry loading station the cement can be loaded into silo lorries for further construction projects in the plant. Agglomeration of the cement after longer storage times in the silos is avoided due to internal cement transfer by pumping in certain intervals.

In the end of February 2012, the Division Mineral Processing of the company MFL landed one of the biggest orders. For kombinat Magnezit – SATkA, a stationary plant for the

“stowage complex” will come into being in South Ural till the end of 2013. This large-scale project consists of three parts: a crushing and screening plant, a grinding-mixing plant, as well as a cement unloading station for railway cars with a silo works. .

NEW MAJOR ORDER FOR MFL FROM RUSSIA

The client „Kombinat Magnezit Satka“ is a magnesite mining company and belongs to “Group Magnezit“, where crushing and screening plants as well as roll crushers and cone crushers made by MFL are already being operated successfully. The follow-up order ”stowage complex” is not only a wonderful success for the company MFL but also for the companies Christian Pfeiffer Maschinenfabrik and SBM Mineral Processing – both companies belonging to the MFL-Group – as their components are integrated in this large-scale project as well.
