Abstract:
Provided is a lifting/lowering device which initializes a calculated amount of movement of an object to be lifted/lowered. The lifting/lowering device comprises: a housing having side walls in a longitudinal direction and an opening in a lower plane; a reel for winding a reel wire by rotating, wherein, as the reel wire is wound up on the reel, the object to be lifted/lowered attached to a distal end of the reel wire is lifted, the object to be lifted/lowered being suspended under the lifting/lowering device; a control unit which calculates an amount of movement by which the object to be lifted/lowered is lifted; and a reset switch installed in the housing. As the object to be lifted/lowered is lifted, the reset switch is depressed, and, when the reset switch is depressed, the control unit initializes the calculated amount of movement.
