NCCCO CORE EXAM PRACTICE TEST
QUESTIONS WITH VERIFIED ANSWERS
2026/2027
1. When lifting a load that is at the maximum capacity for the current configuration, what is
the most critical factor to maintain crane stability?
A. Maintaining the crane within one percent of level.
B. The wind speed at the ground level.
C. The speed of the swing during the lift.
D. The color of the load line used.
Answer: A
Conceptual Explanation: According to ASME B30.5 and OSHA standards, cranes must be
level within 1% grade to ensure the load chart values remain valid and to prevent side
loading of the boom.
2. In a load chart, the area above the bold line or within shaded areas usually represents
capacities limited by:
A. Tipping or stability.
,B. Hydraulic pressure limits.
C. Wire rope breaking strength.
D. Structural strength.
Answer: D
Conceptual Explanation: Capacities listed above the bold line or in shaded areas on a load
chart are based on the structural competence of the crane, whereas those below are based
on stability (tipping).
3. What is the OSHA minimum clearance for a crane operating near power lines rated at 350
kV?
A. 10 feet
B. 20 feet
C. 15 feet
D. 25 feet
Answer: B
Conceptual Explanation: For voltages between 200 kV and 350 kV, OSHA 1926.1408
Table A requires a minimum clearance of 20 feet.
4. If a crane’s Load Moment Indicator (LMI) malfunctions, what is the OSHA requirement for
continued operation?
A. Stop operations immediately until the LMI is repaired.
, B. Operations may continue indefinitely if a signal person is used.
C. Operations may continue for up to 7 days if the load weight is known.
D. The crane must be derated by 50%.
Answer: C
Conceptual Explanation: OSHA 1926.1417(j) allows operations to continue for 7 days if
the LMI fails, provided the load weight is verified by other means, though some companies
have stricter policies.
5. When using a jib, how does increasing the offset angle affect the crane’s capacity?
A. It increases the capacity due to better leverage.
B. It generally decreases the capacity at a given radius.
C. It has no effect on capacity.
D. It only affects the boom tip height.
Answer: B
Conceptual Explanation: Increasing the jib offset angle increases the radius at which the
load is handled, which typically reduces the rated capacity of the crane.
6. Which of the following is considered a ‘deduction’ from the crane’s gross capacity?
A. The weight of the load being lifted.
B. The weight of the fuel in the tank.
