Grade 80 chain WLL chart
Working load limit for one straight, vertical strand of chain. Choose a size whose WLL meets or exceeds the load. In a sling, the WLL also depends on the number of legs and the sling angle: see the chain sling WLL chart. The WLL on a finished sling's tag always governs.
| Chain size | WLL, single vertical strand (lb) | Approx. weight per foot (lb) |
|---|---|---|
| 9/32" | 3,500 | 0.7 |
| 3/8" | 7,100 | 1.5 |
| 1/2" | 12,000 | 2.6 |
| 3/4" | 28,300 | 6.0 |
| 1" | 47,700 | 10.1 |
Grade 80 chain questions
What is Grade 80 chain?
Heat-treated alloy steel chain made for overhead lifting. The 80 refers to its strength: about 800 newtons per square millimeter at its minimum breaking force.
How is the working load limit set?
Grade 80 working load limits use a 4:1 design factor, so the chain's minimum breaking force is four times its WLL. The WLL is the most the chain should ever lift. Breaking force is never a working number.
What is the difference between Grade 80 and Grade 100 chain?
Grade 100 is rated about 25% higher than Grade 80 of the same size. For example, 3/8" chain is rated 7,100 lb in Grade 80 and 8,800 lb in Grade 100. See Grade 100 chain and our Grade 80 vs Grade 100 guide.
Can I use Grade 70 or Grade 43 chain for overhead lifting?
No. Those grades are for tie-down and transport. Use alloy chain, such as Grade 80 or Grade 100, for overhead lifting.
Is chain by the foot a complete lifting sling?
No. Chain alone is not a sling. All attachments must be matched to the chain's size and grade. OSHA 1910.184 requires each alloy chain sling to be proof tested before first use and to carry a tag showing its size, grade, rated capacity and reach. See Sling Proof Testing and replacement tags, or buy a finished chain sling.
Can you build a sling from this chain?
Yes. Call 480-502-2225 with the chain size, grade, number of legs, reach and fittings you need.
