A multi-car elevator control device that can shorten an open and close time of a door is provided. The multi-car elevator control device includes, in an elevator system including a plurality of cars that overlap each other on a horizontal projection plane, an open and close instruction judging part that changes, based on a motor speed or current in a moving time of a car door of a specified car, a control parameter of a car door of another car. According to the configuration, the multi-car elevator control device changes, based on the motor speed or current in the moving time of the car door of the specified car, the control parameter of the car door of the other car, in the elevator system including a plurality of cars that overlap each other on the horizontal projection plane. Therefore, the open and close time of the door can be shortened.

Cabin assembly (10) for an elevator system, the cabin assembly (10) comprises a cabin (12), a chassis (14) configured to rotationally support the cabin (12) about a cabin axis (16) extending through the cabin (12), a circular thrust profile (18) arranged on the cabin (12) substantially concentric to the cabin axis (16), and a drive member (68) configured to engage the thrust profile (18) to rotate the cabin (12) about the cabin axis (16).
