摘要：Detection signals from lever sensor (), sit-down sensor () and vehicle speedsensor () are read into a controller (). A control signal is produced by the controller () toswitch a directional control valve () of a control valve unit () instantly from a floating

position (c) to a neutral position (a) and to switch another directional control valve () froma neutral position (a) to a lowering position (d) when a dump truck () is in travel with thedirectional control valve () of the control valve unit () is switched in the floating position(c). Whereupon, a hoist cylinder () is contracted by a hydraulic pressure force to hold avessel () in a sit-down position on a vehicle body (), thereby preventing the vessel () fromshaking movements like floating up while the dump truck () is in travel.
