The Longshore LowdownGrade and intended use are different questions
A chain’s grade describes a strength classification. It is not the cargo’s weight and does not identify a complete securing system.
Columbus McKinnon distinguishes Grade 70 transport chain from alloy lifting-chain categories such as Grades 80 and 100.
Columbus McKinnon explicitly states that Grade 70 transport chain must not be used for overhead lifting. Securement and lifting are separate applications.
Higher grade alone does not grant lifting approval. RUD warns that lashing chains are not permitted for lifting applications.
Check the actual manufacturer identification and application with the qualified employer contact. Paint color, apparent thickness, and a photograph are not approval evidence.
