Abstract
A shaft door device and a cab door device are included in an elevator system. The shaft door device has a shaft door and a shaft door closer, and the cab door device includes a cab door. The shaft door closer is operatively connected to the shaft door such that a closing force is exerted onto the shaft door. This provides an improved elevator system which allows a quick opening of the shaft door with an energy-efficient and compact door controlling device. This is achieved by including a compensator which can be operatively connected to the shaft door such that the compensator compensates for at least a part of the closing force acting on the shaft door at least in phases during the opening process of the shaft door.
