クラッチ装置。In a clutch device for a hoisting winch such as a crane, which is equipped with a positive type clutch included in each of two winches and a clutch hydraulic circuit that supplies pressure oil to the clutch cylinder of each clutch, The secondary side of the clutch operation valve that controls pressure oil is connected via a pipe, and the pressure oil flowing through the pipe can be arbitrarily reduced to a pressure that can maintain the clutch in a half-clutch state. A variable pressure type pressure reducing valve is provided, and when one clutch operating valve is operated and the clutch is operated by a person, the pressure oil reduced by the variable pressure type pressure reducing valve is transferred to the clutch cylinder of the other clutch, and the pressure oil is transferred to the shuttle valve. A clutch device for a hoisting winch of a crane, etc., characterized in that the clutch device is configured to be supplied via the clutch device.
