What is the minimum grade for chains used for lifting, rigging, or hoisting?

The minimum grade for chains used in lifting, rigging, or hoisting applications is typically Grade 80 Alloy chain. This grade is specifically designed for high-strength lifting applications and is engineered to meet rigorous safety standards. Grade 80 chains are made from alloy steel and have a higher tensile strength compared to lower grades, making them suitable for handling heavy loads safely.

Using Grade 80 chain ensures that the rigging system can withstand the forces exerted during lifting operations without risking chain failure, which is critical for the safety of both the load being lifted and personnel working in the vicinity. This grade is widely accepted in various regulations and industry standards for lifting and rigging, giving operators confidence in their equipment's reliability and safety.

Other grades, such as Grade 60, Grade 70, and Grade 100, serve different specific purposes and applications, but Grade 80 is established as the baseline for safe lifting practices. This distinction highlights the emphasis on strength and safety in lifting operations, particularly in environments where loads are substantial.
