Calculating how horizontal sling angles increase the stress on rigging gear.
A Level 3 Rigger is classified as an Advanced Rigger . While a Level 1 (Beginner) knows basic hitches and knots, and a Level 2 (Intermediate) can perform standard lifts and pre-use inspections, a Level 3 Rigger is responsible for complex operations. This includes engineered lifts, calculating unknown loads, center of gravity determination, and acting as a signalperson for critical lifts.
These notes outline the core knowledge areas required for Level 3 certification exams (such as NCCCO, CIC, or OSHA-based assessments).
At Level 3, a rigger must move beyond estimated weights to precise mathematical verification.
