ABSTRACT:
In an elevator brake that includes brake jaws acting on at least one bearer rope and a device for applying the brake, the speed of the elevator car is monitored by an impulse relay. This relay is connected to a pulse generator that includes a roller driven by the bearer rope of the elevator car. If the speed of the elevator car is too high, a switching signal applying the brake is given before an arresting device responds.
