ABSTRACT:
An apparatus for performing an evacuation journey of an elevator car includes at least one brake control apparatus mounted on the car and an evacuation drive. In the case of an interruption in the normal travel of the car, an evacuation journey is initiated by an evacuation control in the evacuation drive. The elevator brake is released and the evacuation control moves the car to the next floor at a reduced speed. On reaching the next floor, a brake pawl of the brake control apparatus pivots into a switching opening or runs up onto a switching cam and thus initiates the final braking of the car by actuation of a brake control contact. Upon arrival in the door zone, the car and floor doors are pushed partially open by a spring so that confined passengers can further open the doors and release themselves.
