Application and Study to the Buffering Technique in Shaft Hoisting

By discussion to anti-falling buffering scheme for the tackle, the paper makes out the anti-falling buffering device for the tackle, which could solve the buffering and braking problem for the tackle on condition that the brake is out of order, and could operates stably. It applies to each kind of hoist in tall building and shaft. Meanwhile, the paper makes check and analysis to the key technique, and verifies the reliability of the device.
