The forward position of the hydraulic tipping ram reduces the stress on the body and ensures a maximum vehicle stability. Fitted as standard on all models in the JOSKIN range of tipping trailers, a safety valve, placed directly on the hydraulic tipping ram, prevents the body from unexpectedly falling down (e.g. when a hydraulic hose breaks).
The tipping stabiliser is a particularly useful tool when unloading sticky or ‘slow-moving' material that may remain in the body until the last element of the hydraulic tipping ram is extended. In such a case, it is not unusual to have a negative load on the eyelet. The tipping trailer then tends to lift the rear of the tractor. To avoid this, a suspension locking device called "tipping stabiliser" is the solution. For trailers with a bogie, two hydraulic rams installed vertically between the bogie table and the rear axle prevent the parabolic leaves from bending and stabilise the machine. For trailers with a Hydro-Tandem or Hydro-Tridem running gear, an oil blocking device is activated in the axle suspension system and prevents any shock absorbing effect when tipping.
Available as standard on Tetra-CAP, Tetra-SPACE and Delta-CAP and as an option on Trans-EX, this solution increases the versatility of the JOSKIN tipping trailers. It not only facilitates unloading in low buildings, but it also allows to transport more thanks to the possibility of towing a second Tetra-CAP trailer. The side doors are articulated on welded hinges, which are fastened to a steel section. The presence of a large-section gasket around the entire perimeter of the body openings provides a good seal.
