HOIST ROPE SWIVELS
Swivels are normally used as an essential unit in the suspension of balance ropes in mine shafts; alternatively, they can be used for many other applications. They are completely enclosed and both bearing and spindle are protected by dust seals and radial bushes. Additional security is provided by locking screws and the swivel may be locked to prevent rotation if desired. Although the illustrations and dimensions show our standard supply, both tang connections can be modified to suite customer’s requirements. The swivels are made from 1.5% manganese steel to B.S. 2772, Part 2, 1989, in the hardened and tempered condition and the safe working loads given provide a safety factor of at least 10:1 with a miminum of 15:1 on the threaded section of the spindle.
