  • Reference numeral 12 designates a first turning pulley which is attached to the mount arm 11 in a rotatable manner such that the rotor axis of the first turning pulley 12 is oriented horizontally. A rim surface of the first turning pulley 12 projects beyond the edge of the car 2, and the first turning pulley 12 is arranged so as to face one circumferential edge of the sheave 4.
  • Reference numeral 13 designates a second turning pulley which is attached to the mount arm 11 in a rotatable manner such that the rotor axis of the second turning pulley 13 is oriented horizontally.
  • a rim surface of the second turning pulley 13 projects beyond the edge of the car 2, and the second turning pulley 13 is arranged so as to face a circumferential edge of the sheave 4.
  • the first turning pulley 12 and the second turning pulley 13 are disposed in parallel on the mount arm 11.

  • the height of the car 2 becomes smaller.
  • the top clearance to be insured between the lower surface of the top of the shaft 1 and the top of the car 2 can be made shorter.
  • the lower surface of the top of the shaft 1 can be made lower than the height of the top floor of the building, thereby preventing an increase in construction cost, which would otherwise be caused by ensuring a space for installing an elevator system.
  • the main cable 14 is wound around the first turning pulley 12 and the second turning pulley 13 at an angle of about 90 DEG .
  • the diameter of the first and second turning pulleys 12 and 13 can be about 36 times the diameter of the main cable 14, thus diminishing the height of the first and second turning pulleys 12 and 13. Therefore, the height of the car 2 can be reduced, which in turn results in a reduction in the height of the shaft 1. Since both the height of the car 2 and the height of the shaft 1 are reduced, expenses required for constructing a space for installing the elevator system can be diminished.

  • the main cable 14 is wound around the counterweight pulley 6, the top pulley 7, the first turning pulley 12, the sheave 4, the deflector pulley 17, and the second turning pulley 13, in this sequence.

  • the sheave 4 and the deflector wheel 17 are inclined at angles, as shown in FIG. 6.
  • the rim surface of the sheave 4 and the rim surface of the deflector wheel 17 cross each other at an angle of 60 DEG , thus imparting a fleet angle to the main cable 14.
  • the rim surface of the first turning pulley 12 and the rim surface of the sheave 4 cross each other at angle of 60 DEG
  • the rim surface of the deflector 17 and the rim surface of the second turning pulley 13 cross each other at an angle of 60 DEG . Consequently, the fleet angle of the main cable 14 is diminished, and hence wear of the main cable 14 is diminished, thus prolonging the life of the main cable 14.
