Alloy Chain
Alloy Chain
Available from Trinity Sling in many different grades, types, and sizes, including transport, lifting, and security chain. Alloy transport chain used for tie-down applications is usually Grade 7, whereas Grades 80, 100, and 120 alloy chains are all designed for overhead lifting. Trinity Sling stocks CM-branded domestic chain and offers Pewag and Gunnebo brands as European imported offerings. All alloy lifting grades are tested at the factory, link by link, to ensure quality. Higher grades of alloy lifting chains offer higher rated working loads per diameter. Often, a load may be lifted using smaller diameter, higher grade chain, allowing for both cost and weight savings. Trinity’s expert sales staff can answer customer questions and help with alloy chain selection.
