What is the SWL of a 7.1mm diameter 80-grade chain?

The Safe Working Load (SWL) for chains is calculated based on several factors, including the diameter of the chain, its grade, and the material used. In the case of a 7.1mm diameter chain classified as 80-grade, the SWL is determined from standard formulas and tables that relate the diameter and grade of the chain to its load-bearing capacity.

For an 80-grade chain, which is often used in lifting applications due to its high strength, the SWL can typically be calculated using established coefficients that reflect the chain's strength characteristics. When these calculations are applied to a chain of 7.1mm diameter, the SWL corresponds to approximately 1613.2 kg.

This value considers the safety factors typically applied in lifting and rigging practices, ensuring that the chain can safely handle loads well beyond what would cause it to fail, thus providing a robust margin of safety in practical applications. It is essential to adhere to these calculations and standards in order to ensure safe lifting practices in construction and other industries where such equipment is used.
