The trip unit has a trip arm (17) which is set in motion by movement of the lift cabin and can be brought into friction engagement with the guide rail on which the lift cabin and counter weight move. The movement of the trip arm brings the brake shoes (6,9,10) into contact with the guide rail. The trip arm is moved by a compression spring against the guide rail and can be unlocked by an electromagnetic actuator. Independent claim describes method for engaging brake chopper in a lift wherein the trip arm is moved through the movement of the cabin and brings the brake shoes into contact with the guide rail.</p> |
