Abstract (en)
The invention relates to an elevator safety brake unit (10b), an elevator comprising at least two safety brake units mentioned above, and a method for testing said safety brake units. Each safety brake unit comprises a frame part (11), a movable composition movably supported on said frame part, a compression spring assembly associated with said movable composition, and adapted to activate a braking by pushing said movable composition forward, and a coil assembly (16) of an electromagnet disposed in said frame part and adapted to deactivate the braking by pulling said movable composition backwards. Each movable composition comprises at least two movable elements (12), one compression spring (17) for each movable element, and at least one coil assembly (16) adapted to deactivate the braking by pulling said at least two movable elements backwards.
