Abstract

An elevator system (10) includes an elevator car (12) supported for movement within a hoistway by a plurality of ropes (16) secured to the elevator car (12) by a corresponding plurality of hitch assemblies (14). Each hitch assembly (14) includes an adjustable member (18) for adjusting a biasing force exerted by a biasing member (20) on the elevator car (12). The adjustable member (18) varies the length of the biasing member (20) to distribute at least a portion of a supporting force among the plurality of ropes (16) to counter imbalanced loads on the elevator car (12).
