Abstract (en)
Safety brake (14) for an elevator, enabling the movement of the elevator rope (8) to be stopped between a back stop (17) and a bilateral eccentric jaw (18) in both directions of rope movement. The safety brake is self-locking. Its energy source is a spiral conveyor spring (20) which drives a conveyor (19) that pushes the jaws towards the back stop (17), causing the rope to be squeezed between the jaw and the back stop. The conveyor spring is provided with a shaft and wound up by rotating the shaft by means of a winding motor. Between the shaft and the motor there is a magnetic coupling which, when de-energized, activates the safety brake. <IMAGE>
