Due to the design of most trucks, the engine is located directly underneath the driver’s cab. In order to guarantee the accessibility of the engine, a hydraulic system is used. The individually adjustable driver’s cab cylinder plays an important role here. Once activated, the cylinder retracts and initiates the tilting process of the driver’s cab. Once it reaches its end position, the cylinder holds the cab in a fixed position and thus ensures safe access to the engine compartment.
The WEBER-HYDRAULIK patented lost motion system ensures optimum comfort while driving. The cab tilt cylinder establishes a static connection between the chassis and the cab. During driving, however, the damping causes relative movements between these components. To compensate for these shocks, the cylinder must be freely movable while driving. The is possible with the lost motion system.
