To promote a sharp improvement in a usability by installing a first connection connecting a receiver of a wireless installation and a control unit and a second connection connecting a wire pendant device and the control unit separately in a winch body.

A radio signal generated by a transmitter 4 is received by a receiver 6, and this signal is inputted into a selector 17 via a connection 15. In addition, an operation indicating signal by a wire pendant device 3 is inputted into the selector 17 via another connection 16. A selector switch 21 indicates a micro processing unit 18 to judge of whether either of a radio operation by the receiver 4 or an operation by the wire pendant device 3. In a state that the selector switch 21 is turned off, this micro processing unit 18 selects an operating signal out of the ratio receiver 6, recognizing operation by a radio operation. Likewise, in a state that the selector switch 21 is turned on, the micro processing unit 18 selects the operating signal out of the wire pendant device 3, recognizing operation by this wire pendant device 3.
