Suspension Equipement for Hoist & Balance Ropes - Swivels
Swivels are normally an essential unit in the suspension of balance ropes in mine shafts. Alternatively they can be used for many other applications.
RBD swivels are completely enclosed with dust shields and radial bushes to protect the bearing and spindle. Additional security is provided by locking screws and the swivel may be locked to prevent rotation if desired.
Although the photographs show our standard supply both tang connections can be modified to suit customer requirements.
The swivels are made from 1.5% manganese steel to BS 2772: Part 2: 1989, in the hardened and tempered condition.
The safe working loads given below provide a safety factor of at least 10:1 with a minimum of 15:1 on the threaded section of the spindle. All swivels are tested to 2.5 times the safe working load.
