Abstract: The invention relates to a brake and to a method for controlling the brake. The brake comprises a base part, a braking piece movably supported on the base part, which braking piece is configured to be moved between a braking position and a releasing position, a spring, with the spring force of which the braking piece can be dropped into a braking position, a support member for limiting the initial position of the drop-out movement of the braking piece and also a controllable actuator, which is mechanically connected to the aforementioned support member and configured to displace the initial position of the drop-out movement of the braking piece with respect to the braking position.

Abstract: An elevator safety brake unit, an elevator including at least two of the safety brake units, and a method for testing the safety brake units are disclosed. Each safety brake unit includes a frame part, a movable composition movably supported on the frame part, a compression spring assembly associated with the movable composition, and adapted to activate a braking by pushing the movable composition forward, and a coil assembly of an electromagnet disposed in the frame part and adapted to deactivate the braking by pulling the movable composition backwards. Each movable composition includes at least two movable elements, one compression spring for each movable element, and at least one coil assembly adapted to deactivate the braking by pulling the at least two movable elements backwards.
