SuitEd StructurE

The design of the JOSKIN slurry spreaders is based on 3 main ideas

Self-supporting vehicles

The JOSKIN MODULO2 range has a monocoque supporting struc-ture: the tank is welded to a so-called "integral" cradle on the whole length and width. This galvanized assembly is designed to take on, as much as possible, the strains exerted by the hitching and running gear.

independent chassis

The independent chassis is espe-cially designed by JOSKIN in order to combine strength and flexi-bility. This chassis, called "Universal" chassis, is completely independent and takes on all the stresses the sprea-der is subjected to. In this way, the tank is totally protected against vibrations. Moreover, the chassis can be fitted with a 4-point linkage in order to hitch aspreadingtool(injectors,booms).

Multi-module carriers

The notion of multifunctionality is another very important principle at JOSKIN, on which the CARGOconcept is based: with one single car-rier, you will alternately get a slurry tanker, a silage trailer, an agricultural tipping trailer or a muck spreader.

Tank protection Traction ease Construction flexibility

All JOSKIN slurry tankers are in accordance withCE standards thanks to the baffles plates in the tank.

running gEAr

The Modulo2 slurry spreaders in single-axle version are standard fitted with a fixed axle and can be fitted with a running gear suspension with parabolic leaves. As they are slightly curved and mounted between the axle and the bracket, the parabolic lea-ves do not increase the height of the vehicle. They are very flexible as they are quite long, which increases the driving comfort.

One-part continuous axle with self-lubrica-

ting bushes

Maximum clearance for the wheelsHardened U-bolts

JOSKIN assembles its own boggies, thereby offering per-sonally adapted boggies to suit to each slurry tanker.

The distance between the leaves and the axle square are ele-ments adaptable to each machine.

Moreover, all JOSKIN boggies are bolted and adjustable.

To be avoided

Its secret

Single axle suspension

JOSKIN roll-over boggieThanks to their design, the double-axle vehicles with Roll-Over boggie offer an extra suspension system of the wheels and a larger contact surface with the ground. The boggie is made up of 2 axles linked by parabolic leaves and fixed to the chassis by means of a central point. This concept makes it possible to counterbalancethegroundunevenness(upto+/-240mm). Thankstothepositionofthecross-axis(undertheleaves)andthe upper position of the axles at the ends of the leaves, the drawline pushes the front axle over the obstacle. The traction power needed is moreover reduced. That is why this system is advised in case of intensive use on uneven ground.

running gEAr SuSpEnSion

Hydro-TandemSimplicity, axle travel and stability: these are the three keywords for the Hydro-Tandem running gear. The Hydro-Tandem combines the following advantages: the axles can be easily pul-ledovertheobstacles(boggie)andtheyaresemi-independent(tandem).That iswhy it allowsa significant clearance (up to+/-250mm).

Given the conception and construction of the JOSKIN Hydro-Tandem, the vehicles have a very large contact surface on the ground. The ground compression is largely reduced and the ground structure is therefore better protected. The stability of the vehicle will therefore be significantly impro-ved. Each axle is pulled by leaves attached to a fixing element which is located ahead of the axle.

Fourhydrauliccylindersareplacedtwoby twoonbothsidesof the chassis. The cylinders of a same side are linked to each

other in closed circuit and the oil flow takes place according to the communicating vessels principle.

Hydro-TridemThe choice of a tridem is often induced by larger and larger load capacities, by the length of the vehicle and the maximum load supported by the axles. Its design provides a larger contact sur-facewiththeground.Theloadisdistributedoverthe6wheelsand,consequently,evenlydistributedontheground.Finally,itreinforces the stability of the carriage.

The independent double hydraulic circuit works according to thecommunicatingvesselsprinciple.The6hydrauliccylinderson both side of the chassis are linked 3 by 3 and allow a clea-rance up to 250 mm.

Sincethecircuitsoneachsideofthevehicleareindependent,there is a clearance with automatic adjustment of the position of the tridem on both sides. This allows the tandem to always stay in a perfect horizontal position behind the tractor while dri-ving. This horizontality is obtained, not only edgeways, but also crossways. This explains that the vehicle does not incline when driving on winding roads.

The reactivity of the mechanism is guaranteed by the use of large section hydraulic pipes. Two height sensors are mounted on both sides of the chassis for the height adjustment system, either directly connected to a hydraulic function of the tractor or controlledwithanelectricfunction(notelectrohydraulic).

The lifting axle is standard mounted on all "Hydro-Tridem" vehi-cles.The automatic height adjustment is standard fitted on all triple-axle vehicles.

StEEring AxlES

The slurry tankers with steering axles have considerable adavantages•lessdamagetotheground•lessweartothemechanicalcomponentsofyourvehicle•lessshiftingtyres•lesstractionpowerneeded

JOSKIN offers two types of steering axles: the free steering axle and self steering axle.

StEEring AxlES

Self steering axle(s)(steering when reversing And driving forward)

PrincipleThis type of axle is driven from the tractor by way of a hydraulic circuit operating a "steering" cylinder, also called a "sensor" cylinder, which is fixed to the drawbar by a knee-joint. The system is balanced by the compensated cylinders, which exert a similar force in both directions but do not have to be connected to the tractor. As the self steering system automatically corrects the position of the vehicle to take it out of ruts, it turns out to be the safest and easiest solution.The"Hydro-Tridem"runninggearsarestandardfittedwithadoubleselfsteeringsystem(frontandrear axle).

grip And drivE SyStEmS

An inner partition is bolted at the front of the tank (1/3)and allows to keep as much weight as possible on the eye-let when spreading, thereby improving grip and drive.

filling phaseThe volumes before and behind the partition are simultaneous-ly set under depression in order to fill the tank completely

Emptying phaseThe volume behind the partition is set under pressure (rearvolume) in order to keep the front part filled.When the slurry level reaches the lower edge of the partition, an air indraft is created towards the front part in order to empty it.

This weight transfer system is particularly suitable to tankers fitted with a rear spreading tool.

Weight transfer partition

The weight transfer makes the carriage much safer to use and improves the driving comfort.The weight resting on the hitching gear is distributed on the 4 wheels of the tractor and the shocks are absorbed by the hydro-pneumatic hitching suspension.

Triple-axle vehicles have the front lifting axle in their standard equipment.

BrAking SyStEmS

The type of brake system fitted on your spreader obviously de-pends on the equipment of your tractor.JOSKIN can equip its slurry tankers with the following systems:

The mechanical brakes refer to the manual braking system mounted on Modulo2 slurry tankers up to 4000 litres. Actually, it is a parking brake, which means that the vehicle can only be stopped by the tractor. This is the reason why this braking system is only available on spreaders of maximum 4000 litres.

MECHAniCAl BrAKES

The air braking system remains, for the mo-ment, the system giving the greatest flexibility and power.As the loads transported are ever-increasing, it is absolutely necessary to have the most efficient braking system.TheQuadra,X-Trem,EurolinerandVacu-CARGOtankersarestandard fitted with this type of braking system.

Air BrAKES

The hydraulic brakes re-main the most common type of braking system. Modulo2(>5.000l),Kom-fort2 and Cobra tankersare standard fitted with this system.

HYdrAuliC BrAKES

Formachines thatcanbehitched toseve-raltractors,thedualbrakingsystem(madeup of hydraulic and air brakes) is offered in option on the whole range of slurry tankers.

duAl BrAKES

The automatic reverse inertia brake is mainly mounted in Germany onvehicles up to 7000 litres and is similar to the bra-king system used on small road trailers: when the trailer ''catches up'' with the tractor, the system engages the brakes. This system is at the same time safe and comfortable. The axle is of the ''automatic reverse'' type: actual-ly, one has to make sure that the brakes are not locked when reversing.

AuToMATiC rEVErSE inErTiA BrAKES

The spreaders fitted with air brakes have a standard 3-position manualbrakingregulator(fullyloaded,half-loaded,unloaded).

In option, the standard regulator can be replaced by a device that regulates the braking power in proportion to the load, which is measured by a level float gauge.

When your spreader is fitted with a hy-draulic suspension, the braking system in proportion to the load may be opera-ted by a proportional regulator connec-ted to the hydraulic circuit of this axle suspension. The quantity of air allowed in the air braking circuit will depend on the pressure in the hydraulic circuit.

Which pump capacity?The capacity of the pump is used to create the vacuum before starting to fill the tank or to set the tank under pressure during the spreading phase. Then, the pump "merely" has to keep this vacuum or this pressure.Choosinga toobigpumpmostoftenmeanswasting tractionpower and risking to wear the pump prematurely. Do not forget that the effective vacuum rate is always the same, whatever the chosen type of pump may be.Once the capacity of the pump is selected, it is possible to choose a given type of greasing and cooling system.All the pumps delivered by JOSKIN are at least fitted with a forced lubrication system, which operates during the suction and the spreading phase.

direct connection or speed-increa-sing gearbox?Unless when a high spreading flow is needed, the 1000 rpm-version is gene-rally more interesting because, in com-binationwiththeP.T.O.rpmselectoronthe tractor, it spares the engine and is therefore beneficial to the traction capacity of the whole car-riage.

Vacuum pumps WiTHouT lubricationThe Jurop DL pumps are vacuum models with very high capacity (from 14.000 to20.000lair/min).

The DL pump works with "volu-metric" lobes instead of vanes. The rotation of the lobes then creates a depression inside the tank, and makes it possible to suck slurry.

As there is no contact between the moving parts, the pump can work without being lubri-cated.

The pump is simply cooled by air injection. Inlet/outlet col-lectors are part of the pump housing.

The advantage of this type of pump is the high capacity and the limited dimensions. Moreover, the Jurop DL pump is not subject to wear or pollu-tant emissions.

This pump is standard fitted with silencers on the filling and exhaust pipe.

There are currently two models available in the JOSKIN price list: JuropDL140 (14,000 l air/min)andJuropDL200(20,000lair/min).

Two important options for the DL pump: the filters and the tem-peraturealarm.Theadvantageof thefilters (placedbetweenthe pump and integrated at the front of the tank) is that they suck a lot of purified air.

The compression circuit also includes two safety valves: one on the pump, one on the tank. Why? Because the pump is the heart of your spreader and is worth this attention.

ECoPuMPA vacuum pump naturally loses oil with the expelled air. In order to col-lect this oil and to reduce the noise level of the pump, JOSKIN createdanECOPUMP.Principle:withtheECOPUMP,themachinehas a high situated air intake to avoid the entry of dust raised by thetractor wheels, and the filtering grid makes it possible to reduce thenoise level of the pump.

Ball security (anti-spill valve)Based on a float system, the ball security prevents slurry from flowing in the same pipe as the air. Once the tank is full, the ball comes and blocks the pipe.

Self-cleaning syphonThesyphon(capacityof30or60laccordingtothepumpcapacity)is an extra safety between the tank and the pump. The inside pipe is designed in such a way that the syphon empties automatically when the air is expelled.

Tank pressure relief valveAll JOSKIN tankers with vacuum pump are equipped with a tankoverpressuresecurity(accordingtothenormsinforce).

Pressure relief valve (Ø 150 mm)In option, but standard with some pumps and some spreading tools, thehigh-capacitypressurereliefvalve(Ø150mm)allowstoquicklyevacuate the overpressure and to prevent the pump from prematu-rely overheating. Thanks to this option, it is also possible to adjust the spreading flow by acting on the depression rate in the tank.

Communicating gaugeThe communicating gauge is one of the manyoptions for level indication (seechapter Level indicators on page 32).

In spreading phase 53.7 DB 19,5 DB Pump reverserThe tankers with a vacuum pump have a mechanical pump reverser. However, in option, it is possible to have this reverser with hydraulic control: an essential option when using a pumping device such as a pumping arm, a dorsal boom, ... The rever-sing can take place without stepping out of the tractor to start creating a vacuum when on the road.

Hydraulic mixerThis device is a true mixer. It can

be used during transport.

Air mixerThe pump delivers a pressure

The volumetric system uses a pump that sets slurry in motion: the flow is then directed by means of valves. With their very high flow, the volumetric pumps are a new generation of pumps adapted to difficult pumping conditions, i.e. very long pipes, deep pits,...Advantages• Suckingeasilyindeeppits• Regularflow• Highpressuresandflows:recommendedforspreadingsystemswithverylargewidth• Multifunctionality(mixingslurryduringtransport)• Nomodificationoftheslurrydensity(totallyfulltank)

The box is also a slurry stock for the priming of the pump inorder to prevent the pump from running dry, which could damage the pump housing.The spiral pump can be mounted on tankers the drawbar of which is either fixed or equipped with silent-blocks or with a hydro-pneumatic suspension.

A 3-way valve makes it possible to apply, besides the filling and emptying functions, the mixing in closed circuit and the transfer from pit to pit.
