Abstract
Rail brake (1) for an elevator, comprising a brake body attached to the elevator car, a clamp part comprising jaws (3,4) that engage a guide rail (2) via braking surfaces during braking. A spring (10) generates a load on the clamp part to press the braking surfaces against the guide rail, and a magnet whose force produces an effect reverse to that of the spring releases the braking surfaces from the guide rail. The clamp part is floatably suspended relative to the brake body. The motion of the clamp part relative to the brake body is controlled by the guide rail (2).
