Lifting chains mainly refer to fully automatic welded chains. And they use high-quality alloy steel , which have strong tensile strength. Just as its name, we mainly use them in hoisting and overhead lifting. Moreover, we usually assemble them with G80 or G100 hooks, link rings and other rigging accessories to form a chain sling for lifting heavy and cumbersome goods.
Which Chain Grade Should Be Used for Overhead Lifting?
We usually use Alloy Chain Grade 80 or Grade 100 for overhead lifting. ASTM states that alloy chain shall be able to elongate a minimum of 20% before fracture (7.3.5). And to ensure that alloy chain consistently meets this requirement, ASTM requires The use of certain alloying elements in the manufacturing of the steel for alloy steel chain. However, these alloys can vary from company to company.
The three governing bodies of USA Chain Manufacturers are OSHA, ASME & ASTM. People set these safety standards in order to ensure the safety of their employees and the quality of the chains they manufacture.
How Do You Identify A Lifting Chain?
The easiest way is to look at the marking on the chain link. Usually for lifting chains we print the grade on the ring every meter apart. For example, a Grade 80 chain will have a “G80” identifier., and Grade 100 will have “G100” identifier.
