The Walterscheid P.T.O.-shafts fitted as standard on JOSKIN machines directly transfer the drive energy produced by the tractor. To increase the protection of your machine, several shaft securities are available (standard or optional): shear bolt, cam, free wheel, etc.

The JOSKIN factories have some of the most modern paint lines in Europe. During the process, the material is first cleaned and degreased by shot blasting (projection of up to 2,500 kg of steel balls per minute). It is then primed with an Epoxy Ester primer and finished with a two-component paint. The process is completed by drying in an oven at 60°C. In this way, all JOSKIN parts and machines benefit from the best possible protection for a long service life. As standard, JOSKIN applies its traditional yellow and green colours. As an option, however, they can be replaced by those of your choice. The surface protection with industrial paints, such as those used by JOSKIN, is the best way to protect special steel that is not suitable for a heat treatment such as galvanisation.

JOSKIN offers to paint your tank in addition to the hot-dip galvanisation. Once galvanised, the tanker is sanded so that an Ester Epoxy primer can be sprayed onto the surface. Then, after a quick drying, the final coat of paint is applied. The advantage of a tank painted on the outside is purely aesthetic and does not extend the service life in any way compared to the standard galvanisation.

For more comfort, and if not provided as standard, it is always possible to equip your JOSKIN vehicle with a hydraulic parking stand. To limit the number of hoses connected to the tractor, this stand can be controlled via an independent hand pump.

The JOSKIN Power Pack completes the DUAL-STORM assembly: in this case, the motors of both pumps are driven hydraulically via a hydraulic installation (160 l/min at 280 bar). A double-acting industrial valve isolates the tank from the centrifugal pump body. As standard, the DPA proportional flow system controls the STORM pump rpm.

JOSKIN also offers a range of pre-equipment in its programme, so that you can postpone the choice of rear spreading implements and various accessories, such as the filling arm or the dorsal boom, the hydraulic upper door, the tank mixer, etc. The series production and the spare parts book will always allow you to complete your machine in the future.

At JOSKIN, we mainly distinguish two types of slurry tankers: those without a standard pre-equipment for spreading implements (Alpina2 and Modulo2) and the others. Tankers equipped as standard with this type of pre-equipment, such as VOLUMETRA, EUROLINER, etc., can easily be fitted with a linkage and a spreading implement at any time. This reinforced structure also allows the use of the heaviest and widest implements, depending on the configuration of the machine.

All JOSKIN tankers with a vacuum pump are fitted with a tank overpressure security set at + 1 bar. When the pressure inside the tank exceeds this value, the springs compress, the top lid of the valve lifts and the pressure drops rapidly. Once the pressure is reduced to below + 1 bar, the lid returns to its initial position thanks to the return springs.

The vacuum system creates an atmospheric pressure difference between the inside of the tank and the surrounding air in order to fill or empty the tank. By creating a vacuum, the slurry can be sucked up. In the spreading phase, the principle is reversed: the tank is pressurised to expel the slurry. This means that there is no slurry flowing through the pump, only air.

The lobe system uses the mechanical action of two lobe rotors. Their rotation creates a vacuum on the suction side, which attracts the slurry into the pump body. The slurry is then carried through the lobes, along the rotor wall and discharged on the other side. These pumps do not take much place although they have a relatively high capacity. Their suction principle ensures them a maximum stability and eliminates almost all vibrations. Furthermore, they are all equipped as standard with an automatic stop system (optional on TETRALINER) and wear rings. These pumps have many advantages: high filling and emptying speed, possibility of pumping thicker slurry than with vacuum pumps, compatibility with long suction hoses or spreading implements, pumping performance maintained at a depth of more than 3.5 m, standard equipment for mixing and transfer from pit to pit, output pressure higher than 1 bar guaranteeing a good distribution with a high working width, etc.

The spiral pump uses the mechanical action of an eccentric screw to suck in and discharge the slurry. The rotation of the screw inside the stator then creates a series of hermetic chambers that move along the suction/discharge axis. The advantage of spiral pumps is that they only suck up until the liquid reaches their height (not like vacuum models to the highest point in the tank). They then send it to the tank or spreading implement. Sucking up and discharging thick slurry through long suction pipes become then possible. Storage lagoons over 3.5 m deep are emptied within a reasonable time. A 3-way valve allows, besides the filling and emptying functions, the mixing in closed circuit and the transfer from one pit to another one. All spiral pumps on JOSKIN vehicles are ergonomically and compactly positioned at the lowest point of the machine for an easy access and maintenance. The screw inside the pump is continuously immersed in the liquid to be transferred to reduce the risk of cavitation.

A good macerator is essential to make sure the injector works properly: some kinds of slurry (especially cattle slurry) are indeed full of fibres and foreign bodies. And a blocked opening means that the spreading pattern will be uneven and that the user will have to stop working. The solution is the patented JOSKIN SCALPER© system: a highly efficient macerator consisting of self-sharpening, freely rotating circular blades fitted on a blade holder driven by a hydraulic motor. The circular blades (pivoting on their own axis) and the off-centre arched elliptical holes of the blade holder inevitably cut all foreign bodies in the slurry. If the blades hit something too hard, the rotation direction of the SCALPER© is reversed by the “Switch-Matic” system (option) until the obstacle is chopped. In addition, an electric reverser with a control button is installed in the cab for all rear implements with automaton. The hydraulic circuit supplying the engine is isolated by a plug. A drain can be used to detect any defects in the hydraulic seal. The JOSKIN SCALPER© macerators are also sold separately to fit existing injectors. As standard, the macerator is fed via a 6" pipe and a 6" control valve.

Protection bars can be added over the wheel recess to protect animals from bumping into or climbing over it. This option can sometimes be incompatible with the inner partitions.

Optional mud flaps are available to protect the hydraulic box, the compressed air tank, the lubrication unit, etc. from mud and/or stones thrown up by the tractor wheels.

In order to protect the communicating gauge from possible shocks and damages, it can be fitted with an optional protective grating.

The pump, either mechanically or hydraulically driven, is fixed to a lateral support welded to the tank; the pump and its specific equipment will therefore remain connected to the tank.

In order to protect the upper body edge strip from shocks caused by the load or when loading the trailer, it is possible to opt for a PVC protection. It can cover 2 or 3 sides of the body and can easily be replaced in case of wear (bolted structure). When loading sticky materials, such as manure or compost, this protection can also be used as a scraper for the loading implement.
