Rigging Exam



DOCUMENT OVERVIEW:

• This comprehensive study guide contains 200 high-quality multiple-choice
questions designed specifically to replicate the official NCCCO Core
Certification examination .

• Every question is accompanied by a detailed, evidence-based
rationale that thoroughly explains the correct answer and clarifies why each
distractor is incorrect, reinforcing critical crane operating knowledge and
safety competencies required for certification success .



HOW TO STUDY WITH THIS MATERIAL:

1. Simulate Exam Conditions: Take the exam in timed sections (e.g., 50
questions per sitting) without looking at the answers to gauge your baseline
knowledge.

2. Review Rationales Thoroughly: After answering, read each rationale
carefully—not just for the correct answer, but to understand the why behind
the incorrect options. This deepens comprehension beyond rote
memorization.

3. Focus on Weak Areas: Pay extra attention to questions you answered
incorrectly. Revisit the relevant sections of your study materials or the
NCCCO Candidate Handbook for these topics .

, 4. Use for Active Recall: Instead of passively reading, cover the options and try
to recall the answer before looking at the choices. Then, use the rationale to
confirm your understanding.

5. Repeated Practice: Work through the bank multiple times until you can
consistently answer correctly and explain the rationale for each question.



EXAM QUESTIONS



1. A crane operator is preparing to lift a load weighing 15,000 lbs. The load
chart indicates a maximum capacity of 18,000 lbs at the current radius. What
is the correct action to take?
A) Proceed with the lift as the load is within capacity.
B) Proceed with the lift only if the wind speed is below 15 mph.
C) Refuse the lift because it exceeds 75% of the crane's capacity.
D) Wait for the signal person's approval before proceeding.

Correct Answer: A) Proceed with the lift as the load is within capacity.

Rationale: The load (15,000 lbs) is less than the crane's capacity at that radius
(18,000 lbs). This means the lift is within the safe working limits of the crane for that
specific configuration. While factors like wind and communication are always
important for safety, the primary consideration based on the given information is
that the load is within the charted capacity.



2. According to OSHA 1926.1412, what is the minimum frequency required for
a comprehensive annual inspection of a crane?
A) Every six months.
B) Every 12 months.
C) Every 24 months.
D) Every 36 months.

Correct Answer: B) Every 12 months.

,Rationale: OSHA regulation 1926.1412 requires that a comprehensive annual
inspection of the crane be performed at least every 12 months. This is a crucial part
of crane safety and maintenance to identify and correct any deficiencies or wear
and tear before they lead to a failure.



3. Which part of the wire rope is considered to be the most critical to inspect
for wear and fatigue?
A) The end fittings only.
B) The midpoint of the rope.
C) The point where the rope attaches to the drum.
D) The entire length, but especially the sections that run over sheaves and the
drum.

Correct Answer: D) The entire length, but especially the sections that run over
sheaves and the drum.

Rationale: Wire rope must be inspected along its entire length. However, the
sections that pass over sheaves and wrap around the drum are subject to the most
severe bending stress and abrasion, making them the most critical areas to check
for broken wires, kinks, corrosion, and other signs of fatigue.



4. A load is rigged with a single sling. The angle between the sling leg and the
horizontal is 30 degrees. What is the tension on the sling leg if the load weighs
2,000 lbs?
A) 1,000 lbs
B) 2,000 lbs
C) 4,000 lbs
D) 1,732 lbs

Correct Answer: C) 4,000 lbs.

Rationale: Tension in a single vertical sling is calculated as Load / (2 * sin(angle)).
For a single sling, the formula simplifies to Load / sin(angle). Tension = 2,000 lbs /

, sin(30°). The sine of 30 degrees is 0.5. Therefore, Tension = 2,.5 = 4,000 lbs.
The sling and its hardware must be rated for this increased tension.



5. The crane's Rated Capacity Indicator (RCI) is alarming. What is the
operator's primary responsibility?
A) Continue the lift but at a slower speed.
B) Stop the lift immediately and consult the load chart to verify the weight and
radius.
C) Ignore the alarm if it seems to be malfunctioning.
D) Lower the load to the ground as fast as possible.

Correct Answer: B) Stop the lift immediately and consult the load chart to
verify the weight and radius.

Rationale: A Rated Capacity Indicator (RCI) is a safety device designed to warn the
operator of an overloaded or potentially unstable condition. If the alarm sounds,
the operator must stop the operation and assess the situation. This involves
verifying the actual load weight, the current radius, and checking the load chart to
confirm if the lift is within the crane's safe operating limits.



6. Which of the following is NOT an acceptable method for attaching a
synthetic web sling to a load?
A) Choker hitch.
B) Basket hitch.
C) Vertical hitch.
D) Knotting the sling.

Correct Answer: D) Knotting the sling.

Rationale: Knotting a synthetic web sling can severely damage the fibers and
drastically reduce its lifting capacity. It creates a point of high stress and potential
failure. Synthetic slings must be used with proper hitches (vertical, choker, basket)
and hardware to ensure safety and prevent damage.
