Abstract

An elevator system including an elevator car and counterweight interconnected via hoisting roping for movement in the hoistway of a building having a plurality of landings to be served by the elevator car. Compensation for the hoisting roping includes a chain which interconnects the car and counterweight, and a compensator sheave which guides and tensions the chain. The sheave includes a circumferential groove formed by first and second axially spaced elastomeric members, with the grooves being sized such that alternate links of the chain extend edgewise into the groove, while the intervening links rest against the outer peripheries of the first and second members.
