Abstract (en)
A counterweight is provided with a displacement body that is displaceable with respect to the counterweight. A car and the counterweight are suspended by a main rope connected to the displacement body. The counterweight is provided with a weight-side fixed pulley, and the displacement body is provided with a weight-side movable pulley. When the displacement body is pulled by the main rope to be displaced with respect to the counterweight, the weight-side movable pulley is thereby displaced away from the weight-side fixed pulley. A hoistway-side upper return pulley and a hoistway-side lower return pulley are provided in an upper portion of a hoistway and a lower portion of the hoistway, respectively. A drive rope, to which a tensile force is applied through displacement of the weight-side movable pulley away from the weight-side fixed pulley, is looped in succession around the hoistway-side upper return pulley, the weight-side fixed pulley, the weight-side movable pulley, and the hoistway-side lower return pulley. When the drive device rotates the hoistway-side upper return pulley, the car and the counterweight are thereby raised/lowered within the hoistway.
