Abstract
In the course of largely tilting a vessel (3) backward of a vehicle body (2) by a hoist cylinder (10), occasionally the rear end portion of the vessel (3) runs into an embankment (4A) of dumped earth and sand. In consequence, a load by a vehicle weight to be applied to a rear suspension (8A) suspending the side of a rear wheel (8) of a vehicle is rapidly reduced. Therefore, an inner pressure (P) in the rear suspension (8A) detected by a pressure sensor (25) is rapidly lowered. In this case, a controller (27) controls the hoist cylinder (10) according to the inner pressure (P) in the rear suspension (8A) to stop an extension operation of the hoist cylinder (10). This can suppress occurrence of a state where the side of the rear wheel (8) of the vehicle body (2) is raised upward, that is, a jack-up state.
