Abstract
In case a burden is discharged from a vessel (3), the vessel (3) is raised obliquely backward with respect to a vehicle body (2) by a hoist cylinder (10). However, when discharging work is stopped on the way, the vessel (3) is temporarily lowered to a position at which this sits on the vehicle body (2). When the vessel (3) lowers, a weight of the burden left loaded thereon acts on the hoist cylinder (10) as a load in addition to the weight of the vessel (3). A controller (35) determines whether the vessel (3) lowers in a burden loading state based on various detection signals. When the vessel (3) lowers in the burden loading state, switching of directional control valves (20) and (21) is controlled so as to decrease a contracting speed of the hoist cylinder (10), thereby prevent the vessel (3) from colliding against the vehicle body (2).
