Rotation Resistant Rope 19×7 & 8×19

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.

19×7

  • Rotation resistant.
  • Should not be used with swivel.

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.

8×19

  • Rotation resistant.
  • Crush resistant.
  • Increased bendability.
  • Fatigue resistant.
  • Should not be used with a swivel.

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.
