Running Gear
Single axle suspension

Single-axle vehicles are standard fitted with a fixed axle and can be fitted with a running gear suspension with parabolic leaves.

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.

Our choice of running gears

JOSKIN running gears are designed to meet, in every situation and whatever the vehicle, the criteria of reliability, stability, comfort and safety both on roads and in the fields.

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.

The bogie, which is mounted on 11 and 15 T models, 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 counterbalance the ground unevenness (up to +/- 250 mm). Thanks to the position of the cross-axis (under the leaves) and the 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 therefore reduced.

Hydro-Pendul

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
Hydro-Tandem / Hydro-Tridem

The hydraulic suspension ensures an optimal ground pressure and further improves the stability of the whole running gear. The load is distributed over the four or six wheels and, consequently, evenly distributed on the ground. The left- and right-hand circuits are separated in order to prevent any compensation and work according to the communicating vessels principle. The 4 or 6 hydraulic cylinders on both sides of the chassis are linked 2 by 2 or 3 by 3 and allow a clearance up to 250 mm. The lifting axle is standard mounted on all "Hydro-Tridem" vehicles.
