The essentials from this document in plain words. Check the full document before you rely on a figure.
- Grade 80 safety hook with a clevis fitting for direct connection to chain. It locks when a load is applied so slings cannot release while lifting. A back lever releases the hook. Powder coated.
- Conforms to AS 3776, and every hook is 100% magnaflux crack tested.
- For lifting with chains and synthetic slings, with Grade 80 lifting components.
- Working load limit by size: 6mm 1.12 tonne, 8mm 2.00, 10mm 3.15, 13mm 5.30, 16mm 8.00, 20mm 12.50, 22mm 15.00, 26mm 21.20 tonne.
- The table also lists the breaking load (BL), four times the WLL in every size: for example 12.60 tonne for the 10mm hook.
- Each one is marked with CE, its WLL, a trace code linked to its test certificate, and the maker's mark.
Who it helps: Riggers making up Grade 80 chain slings who need a locking clevis hook's WLL and dimensions.
