BF series fall arrester

BF series fall arrester is a safety device for shaft cage. During the hoisting process, once the hoisting wire rope or the connecting device is broken, it can automatically grasp the brake rope, so that the cage is stable and will not fall into the bottom of the well, thus ensuring the safety of personnel and the hoisting equipment from damage. The fall arrester includes: 1. catcher 2. buffer 3. connector 4. tensioning device.
