  • the car 5 has a safety device (not shown) and a connecting portion that connects with the car-side governor rope 10A that is wound around the car-side speed governor 6A.
  • the ascending/descending speed of the car 5 is detected by the car-side governor 6A via the car-side governor rope 10A.
  • the car-side speed governor 6A activates the safety device.
  • the car 5 is stopped by the safety device.
  • the hoist 4 is installed on a machine beam 4A installed at the top of the hoistway 1 in the vertical direction.
  • the machine beam 4A is arranged on one end side of the hoistway 1 in the width direction X.
  • the machine beam 4A is arranged between a lifting area in which the car 5 moves up and down and a widthwise wall surface 1A at one end of the hoistway 1 in the widthwise direction.
