MAX TECHNOLOGYBridon-Bekaert manufactures ropes using rotary hammer swaging and a unique roller compaction process that compacts the outer rope surface as shown. In comparison to traditional Dyform ropes the Max technology further improves rope to sheave contact and improved diameter stability leading to reduced wear on both rope and sheave. Further increased cross-sectional steel area provides a robust con-struction with high breaking force and excellent crush resistance. Improved inter-wire contact ensures optimum spooling performance offering maximum resistance to damage for exceptional service life in the most demanding multi-layer drum applications.

DYFORM 8 MAX CONSTRUCTEX

DYFORMBridon-Bekaert manufactures ropes using a unique Dyforming process that compacts the strands as shown below. The smooth surface of the “Dyform” product provides improved rope to sheave contact leading to reduced wear on both rope and sheave. Increased cross-sectional steel area increases breaking load and improves inter - wire contact ensures that the rope will operate with lower internal stress levels resulting in longer bending fatigue life and lower costs.

High performance plastic impregnation is designed to offer an internal cushioning layer to the inter-strand contact points especially between core to cover on multi-strand low rotation ropes improving bend fatigue and core service life.

Advanced next generation low friction polymer technology incorporating unique additives to further enhance fatigue life of plasticated ropes

Wire rope guidance

To help you understand the complex nature of wire rope this guide aims to impart an understanding of the key factors that need to be considered and correctly balanced when choosing which type of rope will provide optimum service life and safety for a specific task, type of machinery and working environment.

An example rope nomenclature for the rope shown above is given below;

What it means;

6 = numbers of strands

36 = number of wires in each strand

1-7-7+7-14 = Lay-up of wires in the strand

IWRC = Type of core

1960 = Rope grade

B = Drawn galvanised B(Zn)

Wire ropes can also be swaged or Dyformed after completion, further increasing the steel fill factor, whilst creating a smooth surface to the exterior of the rope.

CoresSteel Wire ropes are supplied with either fibre or steel cores, the choice being largely dependent on the use for which the rope is intended.

The principal function of the core is to provide support to the strands and maintain them in the correct positions under working conditions.

Steel CoresSteel cores comprise an independent wire rope (IWRC) or in the case of small ropes, a wire strand (WSC). Such cores prove advantageous in severe working conditions involving low factors of safety, high operating speeds, wide fleet angles and are more resistant to crushing on drums and pulleys. The steel core provides better support for the outer strands, so that the rope retains its shape, resulting in a more effective distribution of stress in the individual wires.

PreformingGenerally, ropes are supplied preformed. In a preformed rope the wires and strands are given the helix they take up in the completed rope.

Definition of Breaking Loads and Forces1. Minimum Breaking Force: The force, in kilonewtons or

pounds force below which the rope shall not break when tested to destruction.

2. Minimum Breaking Load: The load in tonnes or tons corresponding to the minimum breaking force.

3. Minimum aggregate breaking force: The value calculated from the product of the sum of the cross-sectional metallic areas of all the individual wires in the rope and the tensile strength grades(s) of the wires.

Note: The minimum aggregate breaking force is sometimes used when Regulations permit, particularly in Europe. There is a direct relationship between minimum aggregate breaking force and minimum breaking force (through the spinning loss) and users must be absolutely sure that they are comparing like for like when ordering replacement ropes.

When selecting a steel wire rope to suit a particular application the following characteristics should be taken into consideration.

• Strength• Rotation resistance• Fatigue resistance• Resistance to wear and abrasion• Resistance to crushing• Resistance to corrosion• Rope extension

Resistance to RotationIt is important to determine whether there is a requirement to use a low rotation or rotation resistant rope. Such ropes are often referred to as multi - strand ropes.

Six or eight strand rope constructions are usually selected unless load rotation on a single part system or “cabling” on a multi - part reeving system are likely to cause operational problems.

When loaded, steel wire ropes will generate:

• “Torque” if both ends are fixed• “Turn” if one end is unrestrained

TorqueWhen both ends of a rope are fixed, the applied force generates “torque” at the fixing points.

Bridon-Bekaert recommends that once the machine, appliance or lifting equipment has been taken into service, any replacement rope should possess the required characteristics for the duty in question and should, as a minimum, at least comply with the minimum guaranteed breaking force stated by the original equipment manufacturer.

IMPORTANT NOTE FOR CRANE OPERATORS

StrengthThe responsibility for determining the minimum strength of a rope for use in a given system rests with the manufacturer of the machine, appliance, or lifting equipment. As part of this process the manufacturer of the machine, appliance or lifting equipment will need to be aware of any local regulations, standards or codes of practice which might govern the design factor of the rope (often referred to nowadays as the coefficient of utilisation), and other factors which might influence the design of sheaves and drums, the shape of the groove profiles and corresponding radius, the drum pitch and the angle of fleet, all of which have an effect on rope performance.

Once the strength (referred to as minimum breaking force or minimum breaking load) of the rope has been determined it is then necessary to consider which type of rope will be suitable for the intended duty. It is important therefore for the designer to be fully aware of the properties, characteristics and limitations on use of the many different kinds of steel wire ropes which are available.

TurnWhen one end of a rope is free to rotate, the applied load causes the rope to turn.

FORCECREATESTURN

Anchored

Free toRotate

The torque or turn generated will increase as the load applied increases. The degree to which a wire rope generates torque or turn will be influenced by the construction of the rope. Having recognised what can happen when a rope is loaded it is necessary to select the correct type of rope. It should be noted that all ropes will rotate to some degree when loaded.

The diagram below serves to illustrate the differences in rotational properties between the four basic types of stranded rope.

Specific information including the torque factor and the turn value expressed in degrees per lay length for individual rope constructions can be found on page 47.

The tendency for any rope to turn will increase as the height of lift increases. In a multi - part reeving system the tendency for the rope to cable will increase as the spacing between the parts of rope decreases. Selection of the correct rope will help to prevent “cabling” and rotation of the load.

Bridon is pleased to offer advice on any specific problems associated with rope rotation.

Fatigue ResistanceSteel wire ropes are likely to deteriorate due to bend fatigue when subjected to bending around a sheave or drum. The rate of deterioration will be influenced by the number of sheaves in the system, the diameter of the sheaves and drum, and the loading conditions.

Bridon carries out extensive testing on their products, providing comparative fatigue data to allow customers to make an informed choice.

When selecting a wire rope for an application where bending fatigue is a principal cause of deterioration it is important to select a rope containing small wires e.g.

6x36WS(1-7-7+7-14) as opposed to a 6x19S(1-9-9).

Additional resistance to fatigue leading to real cost savings can be achieved by selecting a “Dyform” wire rope.

“Endurance” low rotation and rotation resistant ropes ensure that problems associated with cabling and load rotation are minimised.

3 layer - Low Rotation

2 layer - Rotation Resistant

Standard Dyform

The smooth surface of the “Dyform” product provides improved rope to sheave contact leading to reduced wear on both rope and sheave . Increased cross-sectional steel area and improved inter - wire contact ensures that the rope will operate with lower internal stress levels resulting in longer bending fatigue life and lower costs.

This graph illustrates a “doubling” in life when moving

from Blue Strand 6x36 to Endurance Dyform 6. This same relationship can be found when moving from any construction into an equivalent Dyform construction e.g. 18x7 to Endurance Dyform 18 or 35x7 to Endurance Dyform 34LR.

Resistance to Abrasive WearAbrasive wear can take place between rope and sheave and between rope and drum but the greatest cause of abrasion is often through “interference” at the drum.

If abrasion is determined to be a major factor in rope deterioration then a wire rope with relatively large outer wires should be selected.

The smooth surface of Dyform rope creates better contact and leads to longer life.

Abrasion Resistance vs Bending Fatigue ResistanceWhen choosing a rope for a specific application it is often necessary to reach a balance between the two important rope characteristics of abrasion resistance and the resistance to bending fatigue. An established method of determining the best construction for the rope for the particular operating conditions is by use of the “X- Chart”. By referring to this chart when selecting a rope, the mid-point of the “X” comes closest to a balance between resistance to abrasion and resistance to bending fatigue. As with most engineering challenges, some degree of compromise and trade off of the two properties may be required in order to choose the best rope for the application. This will ultimately depend on the prevailing conditions under which the rope will be expected to operate in and the need to reach an efficient, economical solution.

Crush Resistance In multi - layer coiling applications where there is more than one layer of rope on the drum it is essential to install the rope with some back tension. Bridon recommends a minimum installation tension of between 2.5% and 10% of the minimum breaking force of the rope. If this is not achieved, or in certain applications where high pressure on underlying rope layers is inevitable e.g. a boom hoist rope raising a boom from the horizontal position, severe crushing damage can be caused to underlying layers. Selection of a steel core as opposed to a fibre core will help this situation. Additional resistance to crushing is offered by a Dyform rope resulting from its high steel fill-factor.

Dyform ropes are recommended for multi - layer coiling operations where crushing on lower layers is inevitable.

Rotary hammer swaged Constructex ropes excel to combat problem spooling to minimise damage and crushing on the drum.

Corrosion resistance If the wire rope is to be used in a corrosive environment then a galvanised coating is recommended. If corrosion is not a significant issue then a bright rope can be selected.

Where moisture can penetrate the rope and attack the core, plastic impregnation (PI) can be considered.

In order to minimise the effects of corrosion it is important to select a wire rope with a suitable manufacturing lubricant. Further advantages can be gained by lubricating the rope regularly whilst it is in service.

Properties of Extension of Steel Wire RopesAny assembly of steel wires spun into a helical formation either as a strand or wire rope, when subjected to a tensile load, can extend in three separate phases, depending on the magnitude of the applied load.

There are also other factors which produce rope extension which are very small and can normally be ignored.

Phase 1 - Initial or Permanent Constructional ExtensionAt the commencement of loading a new rope, extension is created by the bedding down of the assembled wires with a corresponding reduction in overall diameter. This reduction in diameter creates an excess length of wire which is accommodated by a lengthening of the helical lay. When sufficiently large bearing areas have been generated on adjacent wires to withstand the circumferential compressive loads, this mechanically created extension ceases and the extension in Phase 2 commences. The Initial Extension of any rope cannot be accurately determined by calculation and has no elastic properties.

The practical value of this characteristic depends upon many factors, the most important being the type and construction of rope, the range of loads and the number and frequency of the cycles of operation. It is not possible to quote exact values for the various constructions of rope in use, but the following approximate values may be employed to give reasonably accurate results.

The above figures are for guidance purposes. More precise figures are available upon request.

Phase 2 - Elastic ExtensionFollowing Phase 1, the rope extends in a manner which complies approximately with Hookes Law (stress is proportional to strain) until the Limit of Proportionality or Elastic Limit is reached.

It is important to note that wire ropes do not possess a Young’s Modulus of Elasticity, but an ‘apparent’ Modulus of Elasticity can be determined between two fixed loads.

The Modulus of Elasticity also varies with different rope constructions, but generally increases as the cross-sectional area of steel increases.

General NotesGalvanizedThe Bridon group has the capability to offer any crane product in either Bright or Galvanized finish. Typically, cranes use Bright ropes in North American and Galvanized ropes in the European Union and the GOM. Globally, local usage standards, application conditions and preference may define the actual rope finish selected.

Smooth Drum“When using multi-strand, rotation resistant products in multi-layer applications, the use of Lebus type grooved drums may provide superior spooling performance over smooth faced drums.”

Minimum Breaking ForceMany wire rope applications, mobile cranes and deep water mooring systems in particular benefit from very high strength to weight ratios. As a result, designers are constantly pushing the specific strength envelope of the wire rope used in their products. Bridon and many other rope companies have responded to these requirements with innovative materials and manufacturing techniques to push rope strengths past the highest values listed in national and international standards.

Properties like strength, fatigue life, crush resistance and stability of physical properties are a function of the materials used, geometry of the design and manufacturing processes employed in the specific rope configuration. Optimizing the configuration to produce highest strength is not achieved without effecting other properties. Fatigue life and long term stability of physical properties are most affected by the techniques employed to produce extremely high strength wire rope. Because of these effects, characteristics of extremely high strength rope need to be understood for specific applications. Please contact Bridon Technical sales to review your specific use.

Cross SectionsThe cross section image is for reference only. Actual cross sections vary due to diameter.

By using the values given, it is possible to make a reasonable estimate of elastic extension, but if greater accuracy is required it is advisable to carry out a modulus test on an actual sample of the rope.

W = load applied (kN)L = rope length (m)EA = axial stiffness MN

Phase 3 - Permanent ExtensionThe permanent, non-elastic extension of the steel caused by tensile loads exceeding the yield point of the material.

If the load exceeds the Limit of Proportionality, the rate of extension will accelerate as the load is increased, until a loading is reached at which continuous extension will commence, causing the wire rope to fracture without any further increase of load.

LubricationDuring the wire rope manufacturing process, the space between the wires is normally filled with petroleum based grease, these greases having a temperature operating range typically of 0°C to +60°C. Synthetic grease with an operating temperature range of -40°C to +90°C may be incorporated. It is important when specifying a particular rope to consider the type of lubricant required for the application and the amount of lubricant required on the exterior of the rope, as the tendency is to produce ropes with less grease on their exterior.

Lubricants may be applied to wire ropes during service to both increase their fatigue performance and protect the ropes from corrosion.

storage guidance.

Ensure the floor or ground is level and capable of supporting the total mass of rope and reel. Bearers may be required to distribute the loading, although most steel reels will be supplied on cradles.

Make sure that there is a free flow of air around the rope and that it is isolated from direct contact with the floor or ground, chemical fumes, moisture, steam and other corrosive agents.

Rotate the reel periodically during long periods of storage, particularly in warm environments and climates, to minimise the migration of lubricant from the rope.

For very large reels of rope, where storing undercover is not practical, the reels will have been supplied on a cradle and the reel should be covered particularly for long term storage, with special protective sheet/tarpaulin to provide protection from the sun, wind, rain, etc.

To minimise the possibility of condensation being trapped between the rope and the packaging, the covering may be secured direct to the cradle. This will allow air to the underside of the reel and rope.

If supplied on a reel without a cradle, the whole package should be supported on a simple frame or cradle that is located on the ground and is capable of supporting the total mass of rope plus reel.

WIRE ROPE STORAGE

Ensure all ropes being taken into storage are clearly identified and are accompanied with a manufacturers certificate.

Store the rope off the ground or floor in a clean, dry, well-ventilated, covered location. If it is not possible to store it inside, cover it with waterproof material or a suitable structure to protect the rope from the sun and rain.

Note: Coverings should be such that water drains away, not become trapped.

WARNING: Failure to comply with these recommendations can result in the rope becoming contaminated with harmful materials and foreign debris. These contaminants can induce corrosion and render the rope unsafe for use.

WARNING: Under no circumstances should the reel be lifted with the aid of the cradle, unless the cradle has been specifically designed, clearly identified and rated that it may be used for lifting purposes.

WARNING: Properties of the rope may be affected i.e. reduction in breaking strength, if the rope is stored for long periods at elevated temperatures e.g. none temperature controlled warehouse; bottom of mine shaft, etc.

troubleshooting guide.

Note 1: The picture illustrates packaging provided by Bridon-Bekaert where the wrapping on the supply reel is already anchored to the cradle and provision for ventilation is provided.

Note 2: The packaging material can be supplied with reflective outer coating and/or insulation to aid temperature control.

Reels which have been supplied fully wrapped may suffer from a build up of condensation between the rope and the packaging material, which can result in corrosion and deterioration of the rope. In these situations it may be necessary to replace the packaging or to ventilate the packaging.

Wire ropes in storage should not be exposed to temperatures above 90°C

Note: Extended exposure to high ambient temperatures can result in a significant higher rope temperature. Hence, where possible to optimise the service life of the rope, ambient temperatures should be maintained below 50°C

Make sure that the rope is protected in such a manner that it will not be exposed to any accidental damage either during storage or when placing the rope in, or taking the rope out of storage.

Wire ropes should be protected from windblown debris (sand, shot blast grit, etc) and stored away from welding activities.

Wire ropes in storage should routinely (ideally every six months) and prior to being taken into use/service be inspected by a competent person for signs of damage/deterioration to either the rope or packaging. During the inspection, if signs of migration and/or deterioration of manufacturing lubricant are evident a suitable rope dressing which is compatible with the manufacturing lubricant should be applied. Contact Bridon-Bekaert or the rope supplier and follow the original equipment manufacturers instruction manual for guidance on recommended products or types of rope dressings, methods of application and equipment necessary to apply the dressing. Please contact Bridon-Bekaert for further advice on limitations to the storage of wire ropes.

Note: It is good practice to remove rope from the store on a ‘first in, first out’ basis, to minimise the time held in storage.

WARNING: Failure to apply the correct rope dressing can render the original manufacturing lubricant ineffective and reduce rope performance.

Troubleshooting Guide

Appendix 11 Troubleshooting Guide

The following is a simplified guide to common wire rope problems. More detailed advice can be obtained from any Bridon distributor. In the event of no other standard being applicable, Bridon recommends that ropes are inspected/examined in accordance with ISO 4309.

PROBLEM CAUSE/ACTION

Mechanical damage caused by the rope contacting the structure of the installation on which it is operating or an external structure - usually of a localised nature.

• Generally results from operational conditions.

• Check sheave guards and support/guide sheaves to ensure that the rope has not “jumped out” of the intended reeving system.

• Review operating conditions.

Broken wires or crushed or flattened rope on lower layers at crossover points in multi - layer coiling situations.

Wire breaks usually resulting from crushing or abrasion.

• Check tension on underlying layers. Bridon-Bekaert recommends an installation tension of between 2% and 10 % of the minimum breaking force of the wire rope. Care should be taken to ensure that tension is retained in service. Insufficient tension will result in these lower layers being more prone to crushing damage.

• Review wire rope construction. Dyform wire ropes are more resistant to crushing on underlying layers than conventional rope constructions.

• Do not use more rope than necessary.

• Check drum diameter. Insufficient bending ratio increases tread pressure.

Opening of strands in rotation resistant, low rotation and parallel closed ropes - in extreme circumstances the rope may develop a “birdcage distortion” or protrusion of inner strands.

Note - rotation resistant and low rotation ropes are designed with a specific strand gap which may be apparent on delivery in an off tension condition. These gaps will close under load and will have no effect on the operational performance of the rope.

• Check sheave and drum groove radii using sheave gauge to ensure that they are no smaller than nominal rope radius +5% - Bridon-Bekaert recommends that the sheave and drum groove radii are checked prior to any rope installation.

• Repair or replace drum/sheaves if necessary.

• Check fleet angles in the reeving system - a fleet angle in excess of 1.5 degrees may cause distortion.

• Check installation method - turn induced during installation can cause excessive rope rotation resulting in distortion.

• Check if the rope has been cut “on site “ prior to installation or cut to remove a damaged portion from the end of the rope. If so, was the correct cutting procedure used? Incorrect cutting of rotation resistant, low rotation and parallel closed ropes can cause distortion in operation.

• Rope may have experienced a shock load.

Wire rope user guide version 1.0


Wires looping from strands. • Insufficient service dressing.

• Consider alternative rope construction.

• If wires are looping out of the rope underneath a crossover point, there may be insufficient tension on the lower wraps on the drum.

• Check for areas of rope crushing or distortion.

One line of broken wires running along the length of the rope indicating insufficient support for the rope, generally caused by oversize sheave or drum grooving.

Two single axial lines of broken wires running along the length of the rope approximately 120 degrees apart indicating that the rope is being “nipped” in a tight sheave.

• Check to see if the groove diameter is no greater than 15 % greater than the nominal rope diameter.


• Check for contact damage.

• Check sheave and drum groove radii using sheave gauge to ensure that they are no smaller than nominal rope radius + 5% - Bridon-Bekaert would recommend that the sheave/drum groove radii are checked prior to any rope installation.


“Pigtail” or severe spiralling in rope. • Check that the sheave and drum diameter is large enough - Bridon-Bekaert recommends a minimum ratio of the drum/sheave to nominal rope diameter of 18:1.

• Indicates that the rope has run over a small radius or sharp edge.

• Check to see if the rope has “jumped off” a sheave and has run over a shaft.

Short rope life resulting from evenly/randomly distributed bend fatigue wire breaks caused by bending through the reeving system.

Fatique induced wire breaks are characterised by flat ends on the broken wires.

• Bending fatigue is accelerated as the load increases and as the bending radius decreases (see G6). Consider whether either factor can be improved.

• Check wire rope construction - Dyform ropes are capable of doubling the bending fatigue life of a conventional steel wire rope.

Short rope life resulting from localised bend fatigue wire breaks.

Fatique induced wire breaks are characterised by flat ends on the broken wires.

• Bending fatigue is accelerated as the load increases and as the bending radius decreases (see G6). Consider whether either factor can be improved.

• Check wire rope construction - Dyform ropes are capable of doubling the bending fatigue life of a conventional steel wire rope.

• Localised fatigue breaks indicate continuous repetitive bends over a short length. Consider whether it is economic to periodically shorten the rope in order to move the rope through the system and progressively expose fresh rope to the severe bending zone. In order to facilitate this procedure it may be necessary to begin operating with a slightly longer length of rope.

Broken rope - ropes are likely to break when subjected to substantial overload or misuse particularly when a rope has already been subjected to mechanical damage.

Corrosion of the rope both internally and/or externally can also result in a significant loss in metallic area. The rope strength is reduced to a level where it is unable to sustain the normal working load.

• Review operating conditions.

Wave or corkscrew deformations normally associated with multistrand ropes.

• Check sheave and drum groove radii using sheave gauge to ensure that they are no smaller than nominal rope radius +5% - Bridon-Bekaert recommends that the sheave/drum groove radii are checked prior to any rope installation.


• Check fleet angles in the reeving system - a fleet angle in excess of 1.5 degrees may cause distortion (see C1.6 and C1.7).

• Check that rope end has been secured in accordance with manufacturers instructions (see C4).

• Check operating conditions for induced turn.

Rotation of the load in a single fall system. • Review rope selection.

• Consider use of rotation resistant or low rotation rope.

Anchored

Force Creates

Turn

Rotation of the load in a multi - fall system resulting in “cabling” of the rope falls.

Possibly due to induced turn during installation or operation.

• Review rope selection.

• Consider use of rotation resistant or low rotation rope.

• Review installation procedure (Section C) or operating procedures.

Core protrusion or broken core in single layer six or eight strand rope.

• Caused by repetitive shock loading - review operating conditions.

Rope accumulating or “stacking” at drum flange - due to insufficient fleet angle.

• Review drum design with original equipment manufacturer - consider adding rope kicker, fleeting sheave etc.

Sunken wraps of rope on the drum normally associated with insufficient support from lower layers of rope or grooving.

• Check correct rope diameter.

• If grooved drum check groove pitch.

• Check tension on underlying layers - Bridon-Bekaert recommend an installation tension of between 2% and 10% of the minimum breaking force of the wire rope - Care should be taken to ensure that tension is retained in service. Insufficient tension will result in these lower layers being more prone to crushing damage.

• Make sure that the correct rope length is being used. Too much rope (which may not be necessary) may aggravate the problem.

Short rope life induced by excessive wear and abrasion. • Check fleet angle to drum.

• Check general alignment of sheaves in the reeving system.

• Check that all sheaves are free to rotate.

• Review rope selection. The smooth surface of Dyform wire ropes gives better contact with drum and sheaves and offers improved resistance to “interference” betweeen adjacent laps of rope.

External corrosion. • Consider selection of galvanised rope.

• Review level and type of service dressing.

• Consider selection of galvanised rope.

• Review frequency amount and type of service dressing.

• Consider selection of plastic impregnated (PI) wire rope.

Internal corrosion.
