Abstract

An example elevator system may include a shaft in which at least one elevator car can be vertically displaced. The elevator car may be coupled to a counterweight via a cable arrangement wherein the cable arrangement has at least one cable portion. Horizontal deflection of the cable portion can be limited by at least one limiting member. In some examples, the at least one limiting member may be configured as a limiting roller that is mounted laterally alongside the cable portion such that it can be rotated about an axis of rotation and can be made to rotate by a controllable rotary drive that depends on a speed and a movement direction of the cable portion.
