What is the minimum grade for alloy chain slings used for overhead lifting?

Alloy chain slings used for overhead lifting must meet specific strength requirements to ensure safety and efficacy during load handling. The minimum grade recognized for these slings is Grade 80. This grade is designed for lifting applications and represents a higher strength-to-weight ratio compared to lower grades, meaning Grade 80 alloy chains can safely handle more substantial loads with less risk of failure.

Using a certified Grade 80 chain sling ensures that the equipment is capable of withstanding the loads encountered in overhead lifting applications, reducing the risk of accidents and improving overall site safety. Higher grades, such as Grade 100, while they exist and are used in certain applications, are not considered the minimum requirement for typical overhead lifting scenarios as per industry standards.
