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.
Abstract: A safety device includes a trigger mechanism for triggering a braking wedges attached to first and second double levers to stop an elevator car. A retaining spring detents with a pin on the first double lever and a tension spring engages either the first double lever or the second double lever. The retaining spring maintains the double levers unactuated during normal operation of the elevator and the spring element actuates the double levers after an actuation of the trigger mechanism by a speed limiter.
