US 11,084,687 B2 · Method for operating a lift system, and lift system

Abstract

A method for operating an elevator system having a shaft system and elevator cars that are moved separately between floors in a circulation operation may involve moving the elevator cars upward in a first shaft and moving the elevator cars downward in a second shaft. A number of shaft positions that can be respectively adopted by the elevator cars and that correspond to the number of elevator cars is defined, and synchronization of movement of the elevator cars may be carried out with respect to these defined shaft positions. Further, each of the elevator cars may be moved according to a travel curve. To synchronize the movement of the elevator cars the travel curve for each elevator car may be adapted to account for positions of the elevator cars in the same shaft.
