As of May 2026, NCCCO Rigger Level II is the advanced credential for riggers who plan and supervise critical, complex, and non-routine lifts. The Level II written exam has 40 multiple-choice questions in 60 minutes, plus a separate Level II practical exam, with Rigger Level I held or passed concurrently as a prerequisite. Level II adds rigorous coverage of critical-lift triggers, written lift plans, center-of-gravity and sling-angle math, multi-crane (tandem) lifts typically de-rated to about 75% per crane, personnel hoisting under OSHA 1926.1431, and engineered below-the-hook devices under ASME B30.20.

Sample NCCCO Rigger Level II Practice Questions

Try these sample questions to test your NCCCO Rigger Level II exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Per OSHA's general critical-lift triggers cited by NCCCO, which lift parameter alone is MOST likely to require a written critical-lift plan?
A.Any lift performed indoors
B.A lift in which the load exceeds 75% of the crane's rated capacity for that configuration
C.A lift of less than 1,000 pounds
D.A lift performed before 7 a.m.
Explanation: A widely used critical-lift trigger is exceeding roughly 75% of the crane's rated capacity for the actual configuration. Site or owner policies can be more conservative, but capacity utilization is the classic threshold that pushes a routine pick into the critical-lift category requiring a written plan, engineering review, and a pre-lift meeting.
2A symmetrical rectangular load weighs 20,000 lb and is lifted by a 4-leg bridle. For capacity calculations per ASME B30.9 guidance, how many legs should the rigger assume share the load?
A.All four legs equally
B.Three legs
C.Two legs
D.One leg
Explanation: ASME B30.9 instructs that for a 4-leg bridle the rigger should treat the load as if only three legs carry the load, because manufacturing tolerances and slight differences in leg length mean two legs typically take most of the weight. Using three legs in the math builds in margin and matches industry practice unless a leveling device is used.
3Two cranes lift one load in a tandem (multi-crane) lift. A common engineered de-rating practice limits each crane to what percentage of its single-crane rated capacity?
A.100%
B.90%
C.75%
D.50%
Explanation: Tandem and multi-crane lifts typically de-rate each crane to about 75% of its single-crane rated capacity to account for load-sharing imbalances, dynamic effects, and synchronization risk. A qualified lift engineer can specify a different value, but 75% is the widely taught planning baseline that Level II candidates must recognize.
4A 10,000-lb load is supported by a 2-leg bridle with each leg at 60 degrees from horizontal. What is the tension in EACH sling leg?
A.About 2,887 lb
B.About 5,000 lb
C.About 5,774 lb
D.About 8,660 lb
Explanation: Tension per leg = (load / number of legs) divided by sin(angle). T = (10,000 / 2) / sin 60 = 5,000 / 0.866 = 5,774 lb. At 60 degrees the tension is only slightly above the vertical share. As the angle drops, tension climbs sharply, which is why Level II riggers must compute, not estimate, sling tension on critical lifts.
5A wire rope sling is bent around a load with a D/d ratio of 1:1 (sling diameter equals the bend diameter). Compared with its straight-pull rated capacity, the sling's working capacity drops to approximately:
A.100%
B.85%
C.75%
D.50%
Explanation: Per common wire rope sling manufacturer charts, a D/d ratio of 1:1 reduces a wire rope sling's rated capacity to about 50%, while a D/d of 25:1 preserves roughly 100%. Sharp bends crush rope strands, concentrate stress, and shorten fatigue life, so Level II planning should specify softeners, larger pins, or shackle bows that restore D/d.
6On a personnel-hoisting lift under OSHA 1926.1431, what is required BEFORE the platform carries personnel for the first time at the site?
A.A trial lift and a proof test of the platform
B.Only a daily inspection
C.A radio check and a signed waiver
D.A second crane standing by
Explanation: OSHA 1926.1431 requires both a trial lift, performed with the platform empty over the planned route, and a proof test of the platform to 125% of the platform's rated capacity before personnel are hoisted. The trial lift confirms clearances, swing, and communication, and the proof test validates the platform and rigging connection.
7Per ASME B30.20, an engineered below-the-hook lifting device must be proof tested by the manufacturer to what percentage of its rated load?
A.100%
B.110%
C.125%
D.150%
Explanation: ASME B30.20 requires manufacturers of below-the-hook lifting devices to proof test each unit to 125% of its rated load before first use and after structural repair. The capacity tag must remain legible, and any modification triggers re-engineering and another proof test. Level II riggers verify the tag and inspection record before use.
8Which lifting device is BEST described as a compression member with slings angled down from each end to the load?
A.Lifting beam
B.Spreader bar
C.C-hook
D.Sheave block
Explanation: A spreader bar is a compression member: the two top slings come together at the hook and the bottom slings angle outward to the load, putting the bar in pure compression. A lifting beam is a bending member with multiple top connections and vertical slings to the load. Selection depends on headroom and the load's required pick geometry.
9A non-symmetrical load is suspected to have its center of gravity (CG) significantly off-center. The MOST reliable Level II response is to:
A.Use shorter slings and hope the load levels
B.Calculate the CG from the engineered drawings and adjust sling lengths so each leg carries its proportional share
C.Use four equal-length slings regardless of CG
D.Skip the lift plan because the load is small
Explanation: When the CG is off-center, equal-length sling legs cause unequal loading; the leg closest to the CG carries more weight, and the far leg may unload entirely. The Level II response is to determine the CG from drawings or a controlled test lift and use unequal sling lengths or an adjustable rigging system so each leg shares the load proportionally.
10Which document is the central deliverable that defines a critical lift before the crane is dispatched to position?
A.A verbal toolbox talk
B.A written critical-lift plan with weight, CG, rigging, crane configuration, environmental limits, and contingency procedures
C.A photo of the load
D.A copy of the operator's license
Explanation: A critical-lift plan documents load weight and CG, rigging selection and capacity, crane configuration and chart, ground bearing strategy, wind and weather limits, communications, lift director and signal-person roles, and contingency steps. It is signed by a qualified person and reviewed in a pre-lift meeting before the crane begins setup.

NCCCO Rigger Level II Study Tips from Top Performers

1Memorize the sling-angle factor table: 1/sin(angle). At 60 deg = 1.155, 45 deg = 1.414, 30 deg = 2.000. These show up in every calculation question.
2For 4-leg bridles without a load equalizer, count only three legs in the math per ASME B30.9. With an engineered equalizer, you may count all four.
3Drill composite center-of-gravity problems: CG = sum(weight times position) divided by total weight. Practice both horizontal and vertical CG for tilting and upending lifts.
4Know the critical-lift trigger of about 75% capacity utilization. Always include all rigging weight (hook block, slings, shackles, spreader bar, BTH device) in the deductions.
5Memorize OSHA 1926.1431 personnel hoisting requirements: trial lift, 125% proof test, anti-two-block, secondary fall protection, manufacturer approval if not designed for personnel hoisting.
6Know each ASME B30 family member: B30.5 mobile cranes, B30.9 slings, B30.10 hooks, B30.20 below-the-hook devices, B30.26 rigging hardware. Match the question to the right standard.
7Tandem (multi-crane) lifts de-rate each crane to about 75% of its single-crane chart. One lift director controls both cranes with synchronized signals.
8Wire rope sling D/d ratio matters: 25:1 keeps full capacity; 1:1 cuts capacity to about 50%. Use softeners or larger pins to restore D/d on sharp corners.
9Practice non-symmetric load math: short leg near the CG carries more weight; use moment balance (weight times distance from far end divided by total length) to find each leg's share.

Frequently Asked Questions

How many questions are on the NCCCO Rigger Level II written exam?

The NCCCO Rigger Level II written exam contains 40 multiple-choice questions and a 60-minute time limit. A separate Level II practical exam covers hands-on advanced rigging skills, and candidates must also hold or pass Rigger Level I.
