The tipping system is standard oil fed. There is an option that makes it possible to replace it by a hydraulic pump, which may be fitted with a hydraulic or electric lowering control.
The position of the tipping ram on the front part of the chassis allows to reduce the stresses to the body and makes the vehicle as stable as possible.
Standard mounted on all models of the JOSKIN tipping trailer range, the safety valve, which is directly placed on the tipping ram, prevents the body from unexpectedly falling down (e.g. when hydraulic hoses break).
The double oscillating frame on which the cylinder is mounted allows to compensate the torsions due to the tipping strains and effectively protects the trailer from distortions.

The tipping stabilizer with weight transfer system (or its pre-equipment) is standard mounted on Hydro-Tandem and Hydro-Tridem.
On a Roll-Over bogie, two rams are connected to the chassis. When tipping, the circuit will exert a pressure on the rear axle of the bogie in order to lock it in its position and in this way stabilize the tipping trailer.
Monocoque tipping trailers are fitted with very resistant synthetic rubber seals all around the body. The door is kept closed by a side locking device (except on vehicles with drop sides).
This system allows a perfect tightness of the JOSKIN tipping trailers, even with small grains.
The doors of the JOSKIN tipping trailers are fitted with two safety devices:
- In order to prevent system damage, a pressure relief valve regulates the oil pressure if the door cannot be completely closed, e.g. due to an obstacle;
- A safety valve on each door ram holds the door in position if hydraulic hoses break or if the tractor stops.
