Abstract:
1. A brake for a lift, comprising a generally u-shape brake housing with two rigidly connected limbs maintained at a fixed spacing from each other, each forming a brake half having an active brake lining, a compression spring for activation of the active brake lining and an actuator for release of the active brake lining, the compression spring producing a braking force against a brake surface located between the limbs when the actuator is deactivated, at least one fixed passive brake lining in addition to and independent from the active brake lining located on each brake half for pressing against the brake surface by the compression spring of the other brake half in the event of a failure of the brake half, and means for mounting the brake for floating travel of the brake housing in a perpendicular direction to the brake surface for engaging the brake surface with the passive brake lining on the brake half by the action of the compression spring of the other brake half in said event of failure of the brake half.
