On Friction for Traction of Elevators

L Wiek

Tuesday 1st October 1996

If the amount of frictions is not critical the use of the formula of Eytelwijn/Euler to describe the relation between friction and traction give a workable base for the design. Under more severe demands the used simplifications of the rope surface, the contact forces and the friction coefficient can lead to less successful installations due to lack of friction, excessive traction and wear. The main subjects of this study, which is carried out under the auspitien of the Dutch LIFT INSTITUUT, are the relation of the friction coefficient, the creep velocity and the contact forces at the wires of a wire rope.
