Dump truck for use as e.g. mining truck for transportation of soil in mines, has energy recovery cylinders i.e. gas pressure cylinders, arranged between vehicle frame and trough and supporting rising of trough

摘要

The truck has a tilting trough (2) located on a vehicle frame (1) and tilted at a horizontal coupled axis. Energy recovery cylinders (4) i.e. gas pressure cylinders, are arranged between the vehicle frame and the tilting trough and support rising of the tilting trough. Hydraulic cylinders (3) are provided between the vehicle frame and the tilting trough. The hydraulic cylinders and the energy recovery cylinders are arranged between the frame and the tilting trough parallel to each other. The hydraulic and energy recovery cylinders are linked at the tilting trough on opposite sides.
