Cabin leveling device, and a truck or tractor fitted with the cabin leveling device

摘要

A cabin leveling device for a truck or tractor cabin (7) with sleeping accommodation, and a truck or tractor (1) fitted with the cabin leveling device. The cabin leveling device includes an actuator (23A; 29) adapted to be operatively associated with suspension means (19, 21, 25, 27, 31) between at least one front wheel (11; 13) of a truck or tractor (1) supported on an earth surface (3) and the cabin of the truck or tractor. Also included in the cabin leveling device is a control device for selectively operating the actuator to alter an angular position of the cabin (7) with respect to a horizontal reference level (5). The angular position of the cabin (7) is altered only by increasing or diminishing a distance between the cabin (7) and the at least one front wheel (11; 13), when the truck or tractor (1) is parked.
