Working Load Limit is the maximum working load which should ever be applied to the product under any condition.
Never exceed WLL of the chain.
Inspect regularly. All chain and chain attachments should be inspected regularly for visible damage, distortion, elongation, corrosion and wear that can cause breakage or reduce strength.
Attachments should have a Working Load Limit at least equal to the chain with which they are used.
Avoid shock loads.
Not for overhead lifting. Use only Grade 80 Alloy Chain for overhead lifting. Proof Coil Chain, High Test Chain, and Grade 70 Transport Chains are not to be used for overhead lifting.
Eliminate all twists and kinks in chain before using.
All dimensions are nominal and all weights are approximate.
