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).

Abstract: A control valve device comprises two direction control valves. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. When a hoist cylinder is telescopically operated to raise or lower a vessel, as the hoist cylinder approaches a stop position, a controller determines that the hoist cylinder gets close to the stop position. Based upon this determination, the controller variably adjusts a flow passage area of the direction control valve using the variable throttle portions or variably adjusts a flow passage area of the direction control valve using the variable throttle portions in such a manner as to slow down or speed up the telescopic speed of the hoist cylinder corresponding to the weight in the side of vessel.

Abstract: There is provided a circulation line (39) for circulating pressurized oil from an accumulator (11) into a housing (15) of a steering valve (14). An orifice joint (41) is provided along the path of the circulation line (39). The orifice joint (41) is removably mounted on the housing (15) of the steering valve (14) from outside. An orifice portion (42) of the orifice joint (41) applies a throttling function to the circulating oil liquid whereby a frictional heat is generated therein. The oil liquid in a warm state flows through a communication passage (21), passages in a spool valve (16), and a low pressure side passage (18B), thus enabling the steering valve (14) to be always in a warm state.

Abstract: A branch line branching from midway of a hydraulic conduit or each of actuator side oil passages to connect a bottom side oil chamber of a hoist cylinder to a tank is provided to the hydraulic conduit or each of the actuator side oil passages. A manual operation valve for variably adjusting the flow rate in accordance with the operation of a lever handle is provided in the branch line. Maintenance work is performed with an engine stopped in this state. Subsequently, when a vessel is lowered onto a vehicle body, hydraulic oil can be discharged through the branch line from the bottom side oil chamber of the hoist cylinder to the tank by opening the manual operation valve, so that the hoist cylinder can be automatically contracted.
