Definitions

  • the present invention relates to a traction-type elevator apparatus having such a structure that a car and a counterweight are suspended in a hoistway by a main rope.

  • a 2:1 roping system In such an elevator apparatus, it is necessary to provide the car and the counterweight with sash pulleys, resulting in a complicated construction and high cost.
  • the RPM of a drive sheave is high, which means there is a fear of an increase in the vibration and noise.
  • JP 11-310372 A discloses a conventional machine room less elevator apparatus constructed such that a car and a counterweight are suspended in a hoistway by a 1:1 roping system by two lines of rope. As compared with adopting the 2 : 1 roping system, such an elevator apparatus allows a reduction of the RPM of the drive sheave by half. However, since the suspension load is doubled, it is necessary to increase the rigidity of the components, such as a driving machine, guide rails, and a support beam, so that there is a fear of an increase in cost and an increase in installation space.
