Grade 80 refers to a specific grade of lifting chain, which is made from a special alloy steel that has a high strength-to-weight ratio. This type of lifting chain is designed for use in heavy-duty lifting applications, such as in construction, manufacturing, and shipbuilding.
Grade 80 lifting chains are typically marked with the letter "G" and the number "80" stamped onto each link. They are known for their high strength, durability, and resistance to wear and tear.
When using Grade 80 lifting chains, it is important to ensure that they are properly sized and rated for the specific application. It is also important to inspect the chain regularly for signs of wear or damage, and to replace any worn or damaged links immediately to ensure the safety of the lifting operation.
In addition, it is important to follow proper lifting procedures when using Grade 80 lifting chains, including using proper rigging techniques, maintaining proper load limits, and ensuring that the lifting chain is properly attached and secured to the load. This can help prevent accidents and ensure safe lifting operations.
