Similarities and Differences Between Four Chain Grades

At Hunter Lift, you can bet on one thing: we know all there is to know about lifting. It’s right there in our name. Our lifting devices serve countless needs and industries and use a variety of systems and materials.

Of course chains are a large part of lifting, and we’re often asked what the differences are between different grades of chains. Here, we’ll look at four chain grades and explore how they differ.

Grade 70 Chain
Grade 70, a transport chain, is often known as truckers’ chain—for obvious reasons. It is gold-colored but made of heat-treated carbon steel, and as a transport chain, is manufactured to meet DOT requirements. That said, it should never be utilized for overhead lifting; it can, however, be used for logging, towing, oil rigs, and as a safety chain.

Grade 80 Chain
Grade 80, a heat-treated steel chain, differs from Grade 70 in that it’s known for its excellent strength to weight ratio; therefore, it can be safely used for overhead lifting. Additionally, it can be used as a towing, safety, and recovery chain.

Grade 100 Chain
Like Grade 80, Grade 100 is known for its excellent strength and its suitability for overhead lifting. Grade 100, however, is even stronger—about 25% more so—and is therefore becoming even more popular than its predecessor (Grade 80), and is quickly replacing it. Of course, as a premium chain grade, it is more expensive.

Grade 120 Chain
As one of the newest of the performance chain grades, Grade 120 is the strongest of these four, due to its unique design. As a result, it is 50% stronger than Grade 80 and 25% stronger than Grade 100 and is very well suited for overhead lifting.

Of course there is no rule that says one chain grade is better than another for any situation; the right choice depends on your specific needs and application. If you have any questions about the above chains, or would like to discuss what’s best for you, please feel free to contact us anytime.
