Abstract

See full text

One elevator system includes an elevator car, counterweight, traction sheave, support wrapped around the traction sheave and suspending the car and the counterweight, a compensation sheave, a compensation member wrapped around the compensation sheave and being affixed at a first end to the elevator car and at a second end to the counterweight, and a tensioner. The support is driven by rotation of the traction sheave to raise and lower the car, and the tensioner is in communication with the traction sheave for linearly displacing a rotational centerpoint of the traction sheave. Another elevator system has an elevator car, counterweight, compensation sheave, compensation rope wrapped around the compensation sheave and being affixed to the car and the counterweight, a traction sheave driving a support suspending the car and the counterweight, and a tensioner in communication with the traction sheave for inducing a variation in tension of the compensation rope.
