Wire Rope

Rotation Resistant Ropes

Rotation Resisitant Rope 19 x 7 & 8 x 19

Widely used for hoisting unguided loads with a single part of rope. Typical applications are hoisting ropes on Derricks, boom cranes, shaft sinking hoists and freely suspended mine hoists. Both 19 X 7 and 8 X 19 are bright, right regular lay wire ropes. 19 X 7

Inner strands are left lang lay; outer strands are right regular lay; the natural rotation tendency of one layer is counter balanced by the other. Not recommended for multiple part lifting. 8 X 19

Inner and outer strands are laid in opposing directions to counter rotation. Although less rotation resistant, 8 X 19 has a higher strength factor. Acceptable for multiple part lifting.
