6.1.11 Truck hydraulic stabilisers
6.1.11.1 Description
The new stabiliser system is mounted to compensate the wear of stabiliser wheels, to increase the
motoricity of the truck and to get a high stability while turning.
The stabilisers work as vehicle dampers with an oscillating movement very limited by the hydraulic oil.
However, when the truck takes a curve, the external stabiliser spring crashes at the turn and the truck
bends. This tilt is detected by an inclinometer, the LAC controls the closing of the valve that blocks the
stabiliser and gives support to the truck.
The stabiliser valves are marked by a colour code:
- Right yellow stabiliser, pump side
- Left green stabiliser, LAC side
If the oil level is too low, the maximum speed of the truck is 2km/h.
