[Current]Lifting components for Grade T(80) and V(100) chain slings
Specifies requirements for forged lifting components for use in chain sling assemblies with corresponding sizes of Grade T chain complying with AS2321. The components include hooks with eyes, clevises or other joining devices, mechanical connecting devices, and any other terminal fittings used in a lifting system based on Grade T chain. This Standard does not apply to welded components other than welded master links, welded multilink assemblies, welded joining links, or components subject to an existing Australian Standard.
