Abstract: An elevator system includes a first lane oriented in a first direction, a second lane oriented in a second direction, a car configured to travel in the first and second lanes, a repositioning unit configured to reposition the car from the first lane to the second lane and from the second lane to the first lane, and a plurality of guide rails disposed in each of the first and second lanes that are configured to guide the car along each of the first lane and the second lane. The plurality of guide rails includes a plurality of rucksack guide rails configured to guide the car when it is at least one of already on the repositioning unit, entering the repositioning unit, or exiting the repositioning unit, and a plurality of lateral guide rails configured to guide the car when it is not in the repositioning unit.

Abstract: A roller guide for guiding a car of an elevator system along a guide rail may include a roller carrier that can be attached to the car and several rollers disposed on the roller carrier. The roller may be configured to roll by their respective running surface on a rolling surface of the guide rail. The rollers may each be mounted movably in the roller carrier with a direction component perpendicular to the rolling surface of the guide rail. The rollers may be mounted in operative connection with one another at least in part by way of hydraulic fluid such that a movement of one of the rollers perpendicular to the rolling surface of the guide rail causes a directionally-opposite movement of at least a second of the rollers. The present disclosure also concerns a car and an elevator system that employ such roller guides.

Abstract: The disclosure relates to an elevator system and a method for operating such an elevator system. The elevator system has a cabin and a first and a second transport path for the cabin. The direction of the first transport path differs from that of the second transport path. A signaling device is located in or on the cabin, which displays a change of the cabin from the first transport path into the second transport path and/or vice versa.
