Abstract:
An elevator may include an elevator car, a plurality of diverting pulleys on the elevator car, one or more hoisting ropes, a traction sheave, and a compensating system. The elevator car may be suspended by the plurality of diverting pulleys on the one or more hoisting ropes. The one or more hoisting ropes may have rope portions going upwards from a first set of the diverting pulleys and downwards from a second set. The rope portions going upwards may be under a first rope tension. The rope portions going downwards may be under a second rope tension. The compensating system may act on the one or more hoisting ropes to perform one or more of equalizing tension, compensating tension, equalizing elongation, and compensating elongation in the one or more hoisting ropes, and keeping a ratio of the first rope tension to the second rope tension substantially constant.
