Anti-fall safety device for passenger hoist

The anti-fall Safety Device is a crucial spare parts for Construction Hoist, it is consist of a circular cone, brake cone, spring, centrifugal weight and so on. When a cage is overspeed, the centrifugal weight will overcome the pressure of spring, causing the brake cone to rotate and the shaft pointed to brake cone will forward spirally. The friction force between the brake cone and crust will be increased gradually ensuring that the cage is stopped gradually. The Anti-fall Device is assembled in cage.
