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.

Abstract: A safety device of a lift system may include a car comprising an evaluation device and a measuring device. Conditions where departure from a door zone with an open car door or where impermissible accelerations/speeds are reached within the door zone are identifiable by way of the evaluation device and output signals from the measuring device. In such conditions, a control signal may be generated for braking the car. A safety circuit may be connected to the evaluation device and ensure a first safe zone in a shaft head of a lift shaft during an inspection run. The safety circuit may have a safety switch, and the car may include a tripping means for tripping the safety switch. The safety switch and the tripping means have a first relative position upon which the first safe zone is based, and entry of the car into the first safe zone during the inspection run is preventable by tripping the safety switch, which leads to generation of the control signal and braking of the car.
