A sheave support system for supporting the sheaves of a multiple sheave assembly relative to a support structure, such as a ski lift tower, which comprises at least two sheave members rotatably mounted on the sheave assembly in spaced parallel relationship for supporting the ski lift cable; at least one main support shaft for movably supporting the sheave assembly relative to the ski lift tower; at least two intermediate support arms mounted on the main support shaft; and at least two intermediate support shafts mounted on opposite ends of the intermediate support arm for rotatably supporting the sheave. The support shaft means comprises a support shaft, a hub member mounted circumjacent the support shaft, and an elastic bushing device mounted between the support shaft and the hub member for connecting the hub member to the shaft member while enabling limited relative rotative movement therebetween of less than approximately 15 degrees and also limiting transmission of vibration therebetween.
