NCCCO Rigger study guide
NCCCO Rigger · Work through your exam, one topic at a time.
CCO Rigger certification is a nationally recognized, internationally accredited credential for the people who handle and move loads - iron workers, millwrights, electricians, mechanics, laborers, linemen, pipe fitters and others who rig as part of their trade. Two levels are offered. Level I covers simple, repetitive rigging tasks where the load weight, center of gravity, rigging and configuration are already known to the rigger; Level II adds weight and center-of-gravity estimation, lift point identification, capacity-based rigging selection, lift-point inspection, and load dynamics. Both levels require a multiple-choice written exam plus a practical exam. Topics on this exam: Inspection of rigging before use, Hitch configurations, capacities, and basic knots, Recognition of associated hazards, and Use of rigging equipment and basic hitches and their applications. The NCCCO Rigger study guide has 4 sections and about 1,402 words.
01Inspection of Rigging Before Use
Pre-use inspection is a go/no-go judgment made before every lift. The user inspects each sling, shackle, hook, and below-the-hook device at the start of the shift and again after any dropping, shock loading, or exposure to heat or chemicals.

The same sling has different working limits depending on how it is attached: Vertical - 100% of the single-leg rating. Choker - typically 75–80%, because the sling is choked on itself; a tighter choke angle reduces it further.

Hazard recognition is tested heavily because nearly every rigging failure had a visible warning. Overhead and buried power lines are the leading cause of fatalities.

Rigging choice depends on weight, geometry, center of gravity, attachment points, and the path the load must travel. Wire rope resists abrasion and heat; chain handles sharp edges and elevated temperatures; synthetic web is light and non-marring but vulnerable to cuts and heat.
