Abstract
A self-centering brake for a lift provides for the same braking moment in the case of normal operation and in the case of failure of a brake half. The brake consists of a housing which is U-shaped in cross-section, wherein a limb of the U corresponds with a brake half. The brake halves are of identical construction. An active brake lining and a passive brake lining are provided for each brake half. The active brake lining is loaded by a spring force of a compression spring. In the case of failure of a brake half the passive brake lining takes over the function of the active brake lining.
