Abstract: In the technical field of elevator systems, so as to provide a measure for preventing an overspeed governor rope inertia from unwantedly engaging a safety gear in an overspeed governor system, which has a governor rope connected to a moving mass of the elevator system, a machinery brake for decelerating the moving mass so as to perform a quick stop of the moving mass, a safety gear mounted to the moving mass, a synchronization linkage for tripping the safety gear and a synchronization linkage blocking device for blocking the synchronization linkage and/or a governor brake for braking the governor rope, it is determined whether a quick stop of the moving mass is performed, and the governor brake or the synchronization linkage blocking device is activated when the quick stop of the moving mass is performed.
