Extra Heavy Duty Chain for Lifting

Lift, hoist, and rig heavy equipment, vehicles, containers, and more with the strongest chain we offer. This chain is graded by weight capacity, so you can pick the best option whether you're hauling a bulldozer or unloading cargo from a ship. Look for the manufacturer's stamp on each link to confirm the grade.

When using fittings with chain, match the trade size and meet or exceed the chain’s grade to avoid chain damage or failure.

Warning: Never use chain to lift people or items over people.

Grade 80 Chain—Your go-to option for most lifting jobs. Rig and lift industrial vehicles, heavy machinery, and shipping containers with this chain.

Grade 100 Chain—For exceptionally heavy lifting jobs. It's approximately 25% stronger than Grade 80 chain to handle larger loads and continuous lifting tasks in settings such as construction and mining.

Steel—Best for dry environments since moisture will cause this chain to rust.

Black Painted Steel—Best for dry environments as paint may chip and corrode over time.

Black Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Wear Gauges

Measure the maximum amount of wear allowed by OSHA on links of Grade 80 or 100 steel chain. If you can insert the gauge over any part of the link, you should take the chain out of service.

Oblong Chain Rings—For Lifting

Also known as master and sling links, a large inner diameter provides room to attach multiple connectors or legs on a sling. Use these chain rings in general lifting applications. All meet strict ASME safety standards for lifting.

Note: Capacities listed are for vertical lifting only. As the angle changes from vertical, the amount of weight the chain ring can lift is significantly reduced.

For Grade 100 Chain—Chain rings for Grade 100 chain are approximately 20% stronger than chain rings for Grade 80 chain.

Powder-Coated Alloy Steel—Powder-coated alloy steel chain rings have mild corrosion resistance.

Flat Thickness—Chain rings with a flat have a spot that's thinner than the rest of the chain ring, so you can slip on connectors that otherwise wouldn't fit. The flat doesn't affect the capacity of the chain ring.
