Single Chain Sling Type

Double Chain Sling Type
Do not exceed working load limit. Use only alloy chain with compatible components of equal working load limit for overhead lifting.

Triple and Quad Chain Sling Type
A quad branch chain sling usually does not sustain loads with even distribution to its four branches, especially when loads are of rigid structure. Therefore, maximum working load limits are set at the same values as for triple branch chain slings of equal quality and size and used with branches at the same angle of inclination.

Standard Triple Branch Magnet Chains

Type 347 Stainless Steel Chain
Although the only chain recommended by NACM, ANSI, and OSHA for overhead lifting is Alloy Chain (Grade 80 or Grade 100), there are occasions when use of Type 347 Stainless Steel Alloy chain with a lower working load limit will provide superior longevity in service. Type 347 Stainless Steel Chain is the preferred lifting chain in some corrosive and elevated temperature environments where the effects of corrosion or extreme heat can have an effect on Grade 80 or Grade 100 chain.

Type 347 chain is available in running lengths as well as single, double, triple, and quad branch sling chains. Sling hooks and grab hooks are available. Chain is embossed SSTL. For long-term exposure at temperatures over 1000°F, creep strength or stress-rupture strength may determine the safe load limits. Do not exceed working load limit. Use only alloy chain and attachments for overhead lifting.
