Claims

[Scope of utility model registration request]

A motor for winding up or unwinding two wires is installed inside the top plate of the outer storage body, and a rotatable shaft is attached to a pulley in the center of the top plate of the inner storage body that moves up and down inside the outer storage body. A direction change pulley is rotatably disposed between the motor and the pulley, and a direction change pulley and an equalizer pulley having a protrusion on the outer periphery are rotatably disposed downstream of the pulley. A stopper is provided between the direction changing pulley and the equalizer pulley, and the stopper abuts against the protrusion when the wire is cut, and the stopper operates the limit switch by abutting against the protrusion of the equalizer pulley. 2 to turn off the motor.
One end of the wire is fixed to the winding drum connected to the motor, and after the middle part is wound around the direction change pulley, pulley, and direction change pulley in order, the other end is fixed to the winding drum connected to the motor. A lifting device characterized in that each equalizer pulley is wound in reverse and fixed to the equalizer pulley.
