running gear

Rocker beam

The rocker beam is available as an option on the 22 and 27 T double-axle models. It consists of two large casings made up of profile tubes (300 x 300 x 12.5 mm) each supporting two half-axles. They are hinged on a central axis (mounted on bushes with grease nipples) and a monoblock table bolted to the chassis.

Cross Over boggie

The Trans-KTP 17, 22 and 27 T tipping trailers are standard fitted with the JOSKIN Cross-Over bogie. It is specially designed to provide the vehicle with the best compromise between ground clearance and traction ease and to meet the specific requirements of the most demanding works. The pivot point on the Cross-Over and Roll-Over bogies lies under the leaves, which provide a further improved suspension quality because of their outstanding resistance to torsions.


On the Hydro-Pendul hydraulic suspension, each axle is mounted on two double-acting hydraulic rams (one on each side of the chassis) Each axle is linked to the chassis by a triangular structure of tubes with a large diameter, the end of which is fastened to an imposing knee-joint, which has a vertical axis in order to make the running gear highly stable.

On the Hydro-Pendul, you can secure your tipping operation with the option "Tipping stabilizer". Its purpose is to lock the hydraulic rams in order to keep them perfectly aligned.

Hydro-Tandem / Hydro-Tridem

Simplicity, clearance and stability: these are the three key specifications of the Hydro-Tandem/Tridem running gear. It combines the following advantages: the axles can easily be pulled over obstacles and they are semi-independent. That is why they allow a significant clearance (up to +/- 250 mm).

Given the design of the JOSKIN Hydro-Tandem/Hydro-Tridem, the ground pressure is perfectly distributed over the wheels. The ground is therefore less compressed, which allows to spare its structure. The stability of the vehicle will therefore also be significantly improved. Each axle is pulled by leaves attached to a fixing element that is located ahead of the assembly.

Four or six hydraulic rams are placed two by two or three by three on both sides of the chassis. Those of a same side are linked to each other in closed circuit and the oil flow takes place according to the communicating vessels principle. The independence of the circuits on each side of the vehicle, combined with the incompressible properties of oil, ensures a perfect side stability and prevents swaying. This explains why the vehicle is less likely to tilt when driving in bends and on hills.

The first lifting axle is standard mounted on all Hydro-Tridem vehicles.
