Abstract

An elevator system including lubricated wire ropes which are held in frictional contact with the cable grooves of a drive sheave by the weight of an elevator car and counterweight. The wire ropes are lubricated with a synthetic lubricant which provides a coefficient of friction between the wire ropes and drive sheave of at least .145.
