A method for operating an elevator system, which may include at least two cars that can move independently of one another within a common elevator shaft, may involve determining with an elevator controller to cause a first car of the at least two cars to perform a transportation process from a start stopping point to a destination stopping point. The elevator controller may determine a starting time and travel parameters according to which the first car carries out the transportation process from the start stopping point to the destination stopping point. The starting time and the travel parameters may be determined by taking into account state parameters of a second car of the at least two cars.

Method for operating a lift system

An example elevator system may include a shaft in which a first elevator car and a second elevator car positioned below the first elevator car are separately movable up and down in a vertical direction along a common guideway. The first elevator car may be coupled to a first counterweight by first suspension ropes and by first compensation ropes, and the second elevator car may be coupled to a second counterweight by second suspension ropes and second compensation ropes. Further, first and second ends of the first compensation ropes may be secured to the first counterweight or to the first elevator car. The first compensation ropes may be guided around at least one roller positioned on a bottom surface of the first elevator car or on the counterweight.

Elevator installation

The invention relates to an elevator system () for a building under construction, comprising a vertical shaft (), in which a temporary machine compartment () is retained, a driving device (), which is arranged in the temporary machine compartment () and which is coupled by means of a supporting cable () to a car () that can be moved vertically up and down in the shaft (), and a speed limiter (), which interacts with a speed limiter cable () arranged in the shaft (). According to the invention, in order to develop the elevator system in such a way that the speed limiter cable () can be extended in a simple manner when the temporary machine compartment () is moved without said action leading to permanently increased energy consumption of the elevator system (), the speed limiter () is arranged on the car () or on a counterweight () connected to the car () by means of the supporting cable (), and that the speed limiter cable () has a first and second cable section (), wherein the first cable section () is clamped in a stationary manner between a cable retainer () connected to the temporary machine compartment () in a stationary manner and a releasable clamping device () arranged in a lower shaft region () and the second cable section () is connected to the first cable section () in the lower shaft region () and is stored in a storage region.
