ABSTRACT:
A device provides an elevator installation with a shortened car travel path to establish a temporary protective space below and/or above the car upon activation of the car safety brake device. The speed limiter cable is limited, independently of the speed limiter, in a travel path by a switchable stop device. This limitation causes an actuation of the car safety brake device in the corresponding travel direction.
