Abstract
An elevator system includes first and second elevator cars movable vertically in a first elevator shaft, a closed support belt routed around lower and upper deflection rollers, a drive machine driving the support belt, and an actuable coupling device arranged on each of the first and second elevator cars. The support belt has first and second coupling elements to and from which the coupling devices can be coupled and decoupled whereby a drive connection between the respective elevator car and the support belt can be established and released. A coupled elevator car is moved in the first elevator shaft by the support belt driven by the drive machine. The coupling elements are arranged such that they are not routed around the deflection rollers during movement of the first elevator car from a lower end position to an upper end position or vice versa.
