Grade 80 Tow Chain

Grade 80 Tow Chain is a heat-treated alloy steel designed for high strength for overhead lifting and tie down applications. It is the most economical of the three chain grade types that are suitable for overhead lifting (grade 80, grade 100, grade 120).

Our grade 80 bulk chain is tested throughout the manufacturing process and meets and exceeds the specifications of NACM, ASTM, and OSHA.

Our selection includes full drums of grade 80 chain, half drums of chain, and cut grade 80 chain by the foot, as well as tie down assemblies.

Grade 80 fittings are also available by calling our sales team . We also offer a full line of Grade 80 Lifting Slings.

If you don’t see what you need, let us know. We have access to a wide range of vendors and chain types. Custom orders are always an option as well.

Grade of Chain: NACM (National Association of Chain Manufacturers & ASTM (American Society for Test Materials) classify chains in various grades. The higher the grade, the higher the working load limit for the same size of chain.

Working Load Limit (WLL): (rated capacity) Is the maximum working load that should be applied In direct tension to an undamaged straight length of chain.

Proof Test: (manufacturing test force) Is a term designating the minimum tensile force which has been applied to a chain under a constantly increasing force In direct tension during the manufacturing process. These loads are manufacturing integrity tests and shall not be used as criteria for service or design purpose.

Minimum Breaking Force: The minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer’s attribute acceptance test and SHALL NOT be used as criteria for service and design purpose.

Overhead Lifting: The process of lifting that would elevate a freely suspended load to such a position that dropping a load would present a possibility of bodily injury or Property damage.
