Best Rotation Resistance
The recommendation on swivels is also confirmed by the Wire Rope Technical Board as taken out of the Third Edition and reads as follows:
“The use of an open swivel (allowed to rotate freely) continuously during operation of the rope is a practice that must be carefully considered. Open swivels are not recommended for use with 8×19, 19×7, and 19×19 rope classifications. For other multi-strand constructions, consult the rope manufacturer for recommendations regarding the use of swivels”.
Note: Tech-35 not only can be used with a swivel, but it is recommended. Tech-35 provides the greatest resistance to rotation of all the rotation resistant ropes available as shown in the chart located to the left.
