Abstract
In an elevator installation an elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. An elevator braking device includes a brake element, a force store, which is constructed to press the brake element against the brake surface, and an actuator, which can act on the brake element and which is constructed in order to press, in a first operational setting, the brake element against the force of the force store away from the brake surface or to hold it at a spacing therefrom and in order to free, in a second operational setting, pressing of the brake element against the brake surface.
