As shown in Publication No. 3, the main rope is wound around a cylindrical drum, one end of which is connected to the drum, and the other end connected to an object to be lifted and lowered. Then, by rotating the drum with a drive machine, the main rope is wound around the drum or unwound from the drum, thereby raising or lowering the lifted or lowered object. Therefore, the lifting and lowering stroke of the object to be lifted and lowered is determined by the amount of main rope that can be wrapped around the drum.
