Abstract
Traction elevators are suspended by multiple ropes. Uneven sheave wears affect the rope tension during elevator operation. If the tension condition reaches o the traction capacity, a rope slip occurs. As the rope slip also affects the rope tension, a tension calculation with rope slip is necessary to evaluate the relation between the groove wear and the rope tension. In this paper, a tension evaluation model is derived by including the rope slip behavior and then the influenc of the rope tension due to the groove wear is evaluated numerically.
