Inline Shortening Sling Assemblies: Leg Length Tolerances

Inline Shortening Assemblies can now be used under the following conditions:

1. As long as the assembly is tested and tagged
2. Up to 16mm – locking shorteners are to be used as an integral part of assembly – see figures a, b, c
3. Over 16mm – A Risk Assessment is required and additional measures taken to ensure the device does not become detached
4. Slings without locking mechanisms – must be accompanied by a warning

The new Standards state that the difference between shorter and longer legs should be no more than:

1. 10mm for lengths up to 2 metres
2. 5mm extra for every metre over 2 metres

NOTE: 

1. The actual length of each sling should not be less than that ordered and should not exceed that ordered by more than two link pitches (refer AS 2321).

2. Each leg of a multi leg sling should consist of the same number of  links as each of the other legs. Specific applications may require  legs to contain a different number of links.
