The friction force between the steel wire rope and the traction sheave is relied on when the elevator car moves. When the elevator is braked, the steel wire rope can slide relatively relative to the traction sheave due to unbalanced stress on two ends of the steel wire rope. The relative slippage of the steel wire rope is one of important parameters of the failure of an elevator traction system, so that the measurement of the relative slippage has important significance on the safety of the elevator.
