NCCCO Core Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This comprehensive examination contains 100 original verified questions designed for professional crane
operator candidates preparing for the NCCCO Core Examination. The questions are distributed equally
across four core domains: OSHA Regulations, Standards, and Site Safety (25 questions), Load Charts,
Capacity, and Equipment Setup (25 questions), Rigging, Signals, and Load Handling (25 questions), and
Equipment Operation, Maintenance, and Inspection (25 questions). Content is original and structured to
reinforce official NCCCO Core Examination objectives for actual exam readiness and professional
proficiency, aligned to the 2026/2027 academic year. Each question includes a correct answer and a
rationale grounded in OSHA 1926 Subpart CC, ASME B30 standards, and foundational crane operation
methodology.
ACTUAL QUESTIONS
Domain 1: OSHA Regulations, Standards, and Site Safety
Question 1. According to OSHA 1926 Subpart CC, who has the primary responsibility for
ensuring that crane operations are conducted safely on a construction site?
A. Only the crane operator
B. Only the site superintendent
C. Only the rigger
D. The employer and all personnel involved in the lift
Correct Answer: D
Rationale: OSHA places overall responsibility on the employer while requiring operators, signal
persons, and other personnel to perform their roles in accordance with the standard, creating shared
accountability for safe operations.
Question 2. Which document must be available on the crane during operations according
to OSHA requirements?
A. The operator’s personal training certificate only
B. The manufacturer’s load charts and operator’s manual
C. A list of all previous lifts performed by the crane
D. The site’s general liability insurance policy
Correct Answer: B
Rationale: OSHA and ASME standards require that the applicable load charts and operating
instructions be available in the cab or at the operator’s station so the operator can determine capacity
under current conditions.
Question 3. When working near power lines, OSHA requires that the minimum clearance
for lines rated up to 50 kV be:
A. 10 feet
B. 15 feet
C. 20 feet
D. 25 feet
Correct Answer: A
Rationale: For power lines up to 50 kV, OSHA 1926.1408 requires a minimum clearance of 10 feet unless
the lines are de-energized and grounded or other specific protective measures are implemented.
Question 4. Who is authorized to stop a lift if unsafe conditions are observed?
A. Only the crane operator
B. Only the lift director
C. Any worker who recognizes an imminent danger
NCCCO Core Comprehensive Examination 2026/2027 | Verified Questions
, D. Only the site safety officer
Correct Answer: C
Rationale: OSHA’s stop-work authority allows any employee who identifies an imminent hazard to stop
operations; this is a fundamental component of site safety culture under Subpart CC.
Question 5. According to OSHA, a qualified rigger must be able to:
A. Operate the crane in the absence of the operator
B. Select and inspect rigging gear and attach loads properly
C. Perform annual certifications on the crane structure
D. Rewrite the manufacturer’s load charts
Correct Answer: D
Rationale: A qualified rigger is defined by OSHA as a person who possesses the knowledge and skill to
select, inspect, and use rigging equipment correctly for the specific lift.
Question 6. Which of the following is required before a crane may be used to hoist
personnel?
A. Only a verbal approval from the site supervisor
B. Compliance with the specific personnel-hoisting provisions of OSHA 1926.1431
C. Use of any available man-basket without further evaluation
D. A minimum of two operators in the cab
Correct Answer: A
Rationale: OSHA 1926.1431 imposes strict requirements for personnel platforms, including trial lifts,
proof testing, and specific equipment configurations before personnel may be hoisted.
Question 7. The purpose of a critical lift plan is to:
A. Document routine lifts for record-keeping only
B. Identify hazards and establish controls for lifts that exceed normal risk thresholds
C. Replace the need for a qualified operator
D. Satisfy insurance requirements without operational relevance
Correct Answer: C
Rationale: Critical lift plans are developed for lifts involving high risk (e.g., multiple cranes, personnel,
or loads near capacity) to systematically identify hazards and implement control measures.
Question 8. Under OSHA, when must a signal person be used?
A. Only when the operator requests one
B. When the point of operation is not in full view of the operator or when site-specific conditions
require it
C. Only for lifts exceeding 50 percent of capacity
D. Never if the operator has a camera system
Correct Answer: B
Rationale: OSHA 1926.1419 requires a signal person when the operator’s view is obstructed or when the
lift conditions necessitate additional communication to maintain safety.
Question 9. Which OSHA standard specifically addresses cranes and derricks in
construction?
A. 29 CFR 1910.184
B. 29 CFR 1926 Subpart CC
C. 29 CFR 1915 Subpart G
D. 29 CFR 1926 Subpart L
Correct Answer: C
