Elevator installation

An elevator system comprising:

• a shaft in which an elevator car is vertically displaceable;
• a cable arrangement for coupling the elevator car to a counterweight;
• and
• a limiting roller for limiting horizontal deflection of a portion of the cable arrangement, the limiting roller mounted laterally alongside the cable arrangement and rotatable about an axis of rotation, wherein the limiting roller is rotatable by a controllable rotary drive depending on a speed and a direction of movement of the portion of the cable arrangement, with the controllable rotary drive being disposed laterally alongside the limiting roller.

An elevator system comprising:

• a first elevator car;
• and
• a second elevator car disposed either above or below the first elevator car, wherein the first and second elevator cars are displaceable vertically upwards and downwards separately from one another in a shaft, wherein each of the first and second elevator cars is coupled to a counterweight via at least one cable arrangement, wherein at least one of the cable arrangements includes two cable portions that extend vertically in the shaft from one of the first and second elevator cars along mutually opposite sides of the other elevator car that is disposed between the two cable portions;
• and
• at least one limiting roller rotatably mounted laterally alongside each of the two cable portions in the shaft and/or on the elevator car disposed between the two cable portions.

An elevator system comprising:

• a shaft in which at least one elevator car is displaceable vertically upward and downward;
• a cable arrangement for coupling a counterweight to the at least one elevator car;
• and
• at least one limiting member for limiting horizontal deflection of at least one cable portion of the cable arrangement, wherein the at least one limiting member is configured as a limiting roller that is mounted laterally alongside the at least one cable portion, the limiting roller being rotatable about an axis of rotation by a controllable rotary drive depending on a speed and a movement direction of the at least one cable portion, with the controllable rotary drive being disposed laterally alongside the limiting roller relative to the axis of rotation of the limiting roller.
