These return sheaves 17 and 18 are disposed such that axes thereof extend in a horizontal direction. Furthermore, the car return sheave 17 is disposed so as to overlap with the car 4 within a vertical plane of projection.
  • the first end portions of the main ropes 12 are connected to the counterweight rope fasteners 13, the main ropes 12 are wound in sequence around the counterweight suspension sheave 16, the counterweight return sheave 18, the drive sheave 11, the car return sheave 17, and the suspension sheaves 15, and the second end portions of the main ropes 12 are connected to the car rope fasteners 14.
