Abstract (en)
[origin: WO2016202643A1] In an elevator system, a belt-type suspension means is guided over at least one pulley. A contact surface of the pulley has an anisotropic structure for interacting with the belt-type suspension means. A friction co-efficient between the suspension means and the contact surface in the circumferential direction of the pulley is greater than a friction co-efficient between the suspension means and the contact surface in the axial direction of the pulley.
