Side loading and angle of loading

When rigging with multiple sling legs or where side loading may occur, reduce the rated load as shown below.

Rated load reduction by side loading angle

In-line (0°) to 5°None
6° to 45°30%
45° to 90°50%
Over 90°Do not use
  • Always position the lifting point next to the lock and loop.
  • Lock the shackle securely during use.
  • The abrasion-resistant sleeve must cover all contact points.
  • Never place the load on the loop or crossover area.
  • Never exceed a 120° included angle, and keep at least a 30° horizontal angle of loading.
