The primary responsibility of a Rigger III is the safe preparation and attachment of loads. This involves a deep understanding of basic rigging hardware, such as wire rope slings, synthetic web slings, shackles, and hooks. A Rigger III must be proficient in pre-use inspections to identify defects like kinking, fraying, or deformation that could compromise a lift. Mastery of load weight estimation and the selection of the correct hitch—whether it be a vertical, choker, or basket hitch—is critical to ensuring that the center of gravity is maintained and the load remains stable during transit.
