Abstract

The brake system (4) for an elevator cage, to prevent an uncontrolled descent, has a moving brake unit (4.1) with surface teeth facing a fixed rail (4.2) also with a toothed surface structure. The moving brake unit is fitted to the elevator cage, and the fixed rail is at a carrier pillar. When the elevator cage is at the selected floor level, the moving unit is extended to mesh with the teeth at the rail, in a positive fit, to prevent movement of the elevator cage upwards or downwards. The toothed structure of the fixed or moving sections is a rubber strip or an injection molded profile.
