<p>According to a control device for a hydraulic winch of the present invention, a regulator (18) controls a motor capacity of a hydraulic motor (1) having variable capacity functioning as a driving source of the hydraulic winch in response to a load pressure, a negative brake (12) stops and retains the hydraulic motor at an automatic shutoff for prevention of overloading, and a controller (25) sends signals to the regulator via a regulator-controlling valve (26) at the automatic shutoff to set the motor capacity at a large value. Thus, the delay to recover the motor capacity at the time of returning from the automatic shutoff that is activated during winding-up of a load does not occur, and a control response is increased.</p> |
