Lifting Bow Shackle (Safety Pin) Data Sheet: WLL, Dimensions and Usage Guide

Key things to remember

The essentials from this document in plain words. Check the full document before you rely on a figure.

• ✓Grade S, hot dip galvanised with a yellow safety pin. Made and marked to AS 2741 and approved for lifting.
• ✓WLL from 0.33 tonne (ULSHGSGBS-05) to 55 tonne (ULSHGSGBS-63), for example 2.00 tonne for ULSHGSGBS-13 and 4.70 tonne for ULSHGSGBS-19.
• ✓Assembly: the pin must go the full depth of the screwed eye, be screwed tight into its matching nut, and the safety pin then fitted to the end. Never swap in a pin of a different grade or size.
• ✓Remove visibly bent, overly tight or misaligned shackles from service.
• ✓Use only between -10°C and 200°C. Avoid moves where the load can roll and unscrew the pin, and use loose spacer washers to keep the load central; never weld them on.
• ✓When a bow shackle joins two slings, the slings go in the body and the hooks on the pin, and the WLL should be reduced once the angle between the slings is over 60°.
• ✓Marked with CE, WLL, grade, the maker's mark and a trace code linked to the test certificate.

Who it helps: Riggers and anyone using shackles in lifting, rigging or tension systems who needs the WLL and the assembly and usage rules.
