The trigger assembly 40 pushes the safety clamp assembly 30 to be clamped on the guide rail 50 under the action of external force, and the elastic reset is realized after the external force disappears.

A compensating rope tensioner is provided between the car and counterweight and a wire rope 62 passes through the tensioner member 60 and is connected to the car and counterweight, respectively. Two guide rails 50 are provided and arranged oppositely, and the tension pulley member 60 and the anti-bouncing member are slidably provided on the guide rails 50.
