Abstract
A truck comprises a frame with a driver's cab fixed on the frame and a load carrier which is normally fixed on the frame but is frictionally slidable longitudinally of the frame in the event of a longitudinal impact exceeding a predetermined value. A first hydraulic unit connected between the frame and the load carrier comprises a cylinder and piston of which one is fixed to the frame and the other to the load carrier. A front bumper is mounted on the front of the frame with a second hydraulic unit and a rear bumper is mounted on the rear of the frame with a third hydraulic unit. The second and third hydraulic units are connected with the first hydraulic unit so that fluid pressure is transmitted to the first hydraulic unit in the event of impact with either bumper.
