Overhead Certification of Crane Operators (CCO) Practice Test

Overhead cranes rely on chain slings that can safely handle dynamic lifting loads. OSHA requires the chain used for lifting to be alloy steel because it provides the necessary strength, toughness, and wear resistance, and it can be clearly marked for inspection and rated capacity. This solid performance under shock loading and abrasion reduces the risk of sudden chain failure during crane operations. Magnetic, coated, or non-type-specific chains don’t meet those requirements for lifting in crane systems, so alloy steel chain is the standard specified for safe overhead crane work.
