Alloy chain slings are tough, but they can be weakened by overload, heat, chemicals and impact. A methodical inspection catches problems before a link fails under load.
Before every use
- Check the identification tag: grade, working load limit and examination status.
- Look along each leg for twisted, bent, nicked or gouged links.
- Inspect master links, couplers and hooks, including the hook safety catch.
At thorough examination
The chain is cleaned and examined link by link. Inspectors measure for stretch over a gauge length and for wear at the link bearing points, comparing results with the manufacturer’s limits and standards such as EN 818-6.
Signs of heat or chemical damage
Discoloration, weld spatter, pitting or cracking are reasons to quarantine the sling until a competent person decides.
No legible tag means no known capacity — and no lift.
