In addi- tion, the model of calculating the rope creep and the rope creep difference were established respectively, and the method of computing difference value between the radius of rope grooves considering the rope creep was proposed. The field testing indicates that this method can accurately reflect difference value between the radius of rope grooves, which provides reliable bases for the adjustment of rope unbalanced tension.
