Swivels
Swivels with friction bearings, turnable connector between winch rope and cable grip. The friction bearing guarantees
that the swivel reduces rotation and torsion with increasing pulling force. Swivels with ball bearings turn off and destroy
the steel ropes, they can only be used in connection with absolute twist free steel ropes.
- Swivels for underground cables must be equipped only with friction bearings.
- With increasing pulling force friction bearings twist harder and thus avoid the untwisting of the pulling rope
- Ball bearings let untwist the ropes and leads to destruction.
- kN = minimum breaking load
