Titre : (EN) ELECTRIC WINCH DEVICE
Abrégé :
(EN) Provided is an electric winch device in which irregular winding of a wire rope caused by the landing of a wound-down suspended load can be prevented. This electric winch device is provided with: a winch drum (5) around which a wire rope (2) is wound; an electric motor (8) that rotates the winch drum (5); an operating lever (13a); a measuring unit (18) that measures a tension index value corresponding to the tension of the wire rope (2); and a controller (12) that controls the operation of the electric motor (8). The controller (12) stops the operation of the electric motor (8) when the average value of the tension of the wire rope (2) is equal to or less than a predetermined reference tension value in a state in which an operation in the unwinding direction is applied to the operating lever (13a) the average value of the tension of the wire rope (2) corresponding to the average value of the tension index value over a predetermined time period.
