How to find the right Chain Links AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Chain Links
- Rated coupling vs quick link
- For lifting with alloy chain, use grade-marked coupling or connecting links of the same grade as the chain (grade 80 or 100). Quick links are acceptable only where marked with a working load limit. Generic quick links and repair links are often far weaker than the chain they join.
- Quick link closure
- Screw the nut fully closed, wrench-tight, before loading. An open or partly closed quick link loses most of its strength and can spread.
- Cold shuts and repair links
- Reserve cold shuts and lap links for non-load or light utility use only. They are open-joint designs that are not rated for lifting.
- Size fit
- Match the link to the chain trade size so that it seats in the end links without forcing. Forced or mismatched links side-load and bend.
Brands that matter
- Crosby: Rated connecting links and Hammerlok-style alloy couplers.
- Campbell: Quick links, repair links and grade-matched alloy connectors.
- Peerless: Alloy chain connectors matched to their chain grades.
What to avoid
- Cold shuts or lap links in lifting slings.
- Quick links with no load marking used overhead.
- Welding a link closed, which destroys heat treatment on alloy chain.
Questions
Can I join two lengths of alloy lifting chain with a quick link?
Only with a link marked for that grade and size. The standard method is a grade-matched mechanical coupling link.
