The invention relates to an elevator installation having a shaft in which at least two cars arranged one above another and separately from one another can be moved upward and downward in the vertical direction, each car being assigned a traction drive. In order to develop the elevator system in such a way that the cars can be moved at large and small distances from one another in a constructionally simple way without any risk of collision, at least two cars, according to the invention, can be coupled to one another via a variable-length detachable coupling device, wherein the distance between the cars coupled to one another can be varied with the aid of at least one of the traction drives, depending on the relative speed between the two cars. |
