Abstract

See full text

Provided is an electric winch apparatus capable of preventing irregular winding of a wire rope caused by landing of a hoisted-down suspended load. The electric winch apparatus includes a winch drum (5) around which a wire rope (2) is wound, an electric motor (8) which rotates the winch drum (5), an operation lever (13a), a measurement unit (18) which measures a tension index value corresponding to a tension in the wire rope (2), and a controller (12) which controls motion of the electric motor (8). The controller (12) stops motion of the electric motor (8) when an operation in a lowering operation direction is applied the operation lever (13a) and a tension average value as an average value of a tension in the wire rope (2) becomes less than or equal to a predetermined tension reference value, the average value of the tension corresponding to an average value of the tension index value in a predetermined period.
