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.

Abstract: An elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. The elevator braking device has a brake housing and a force store. The brake housing is mounted to be displaceable between a first position and a second position. The force store acts on the brake housing and pushes the brake housing in the direction of a second position. In addition, the elevator braking device includes an actuator which can act on the brake housing and keep the brake housing in a first position. The actuator in its first setting can hold the brake housing in the first position against the force of the force store. In a second setting the actuator enables pushing of the brake housing into the second position. A brake element is thereby brought into contact with the brake rail.

Abstract: An elevator brake includes a housing and a brake unit, which is movable in an axial direction on a path between a braking position and a starting position, which includes at least one pull unit, and which is moved at least by a first spring force of at least one brake spring. A movement in the axial direction against the spring force of the at least one brake spring is generated by a stroke unit, which generates a stroke, at the pull unit of the brake unit. The first spring force of the at least one brake spring is reduced by a second spring force of a compensating spring stressed by the stroke of the stroke unit.

Abstract: A code strip has per meter a specific number of grid positions, which are provided in alternating sequence with openings and webs. A sensor can detect, for example, the travel direction of an elevator cage from the alternating sequence of the openings and webs. The code strip can be produced at, for example, the factory with alternating openings and webs per meter and adapted on site to the specific requirements of an elevator installation by breaking off the webs. Through breaking off the webs over a length a door zone, for example, is represented on the code strip.
