About Liftrix
Round Edge
A larger bend radius helps reduce stress concentration on the chain. No additional edge deration applies under this loading condition.
Beveled Edge
A tighter bend radius increases stress on the chain and reduces lifting efficiency. Under this loading condition, a deration factor of 0.75 applies to help reduce overload risk.
Sharp edge
A smaller bend radius increases stress concentration on the loaded chain link. Additional edge deration applies under this loading condition with a reduced factor of 0.5.
Best practice is to minimise edge loading using suitable packing or edge protection such as timber, rubber, or protective sleeves to help reduce stress concentration on the chain.
Solution to Minimise
Suitable edge protection such as timber, thick rubber, sleeves, or corner protectors can help spread the load more evenly, reduce corner loading forces, and assist in protecting chains, slings, and wire ropes from damage caused by sharp or tight edges.
