47,793 ELEVATOR SYSTEM ABSTRACT OF THE DISCLOSURE An elevator system including an elevator car and counterweight, hoist roping, and chain compensation for the weight of the hoist roping. A chain wheel spaces and guides the compensating chain. Vibration in the elevator car, and airborne noise due to the chain, are substantially reduced by a mounting assembly for the chain wheel which mounts the chain wheel on springs. The springs are adjustably biased to partially support the weight of the chain wheel, to reduce the loading on the compensating chain.
