Abstract:
PROBLEM TO BE SOLVED: To provide an electric winch apparatus which monitors two wheel chairs by one control unit while suppressing the required number of ports.SOLUTION: An electric winch apparatus comprises: two electric winches including a drum member on which a belt for traction of a wheel chair is wound, a motor for rotating the drum member, a sensor which outputs a pulse signal according to said rotation, and an electromagnetic clutch which so makes the drum member and the motor as to be in a coupling state by electric conduction and so makes the drum member and the motor as to be in an open state by releasing electric conduction; a feed section which feeds electric current or voltage for electric conduction of the electromagnetic clutch; a changeover section which changes a feed destination of the feed section to any one of the electric winches; and a control section. In the case where retraction of any one of the wheel chairs is detected based on the pulse signal, the control section so changes the changeover section as to make the electromagnetic clutch of the afore-said electric winch, which tows the retracted wheel chair, as to be a feed destination.SELECTED DRAWING: Figure 1
