NCCCO Tower Crane Exam Questions With Accurate
Answers 100% Guarantee Pass 2026/2027
1. Describe the significance of connecting each leg of a wire rope bridle to the
load line hook in crane operations.
It reduces the overall weight of the rigging system.
It prevents the load from swinging during transport.
It allows for easier maneuvering of the personnel platform.
Connecting each leg of the wire rope bridle to the load line hook
ensures balanced load distribution and safety during lifting
operations.
2. If a tower crane fails to meet one of the monthly inspection requirements set
by OSHA, what should the operator do?
Cease operation until the issue is resolved.
Ignore the requirement if the crane is functioning.
Notify the operator only.
Continue operation if the issue seems minor.
3. What does the acronym ASME represent in relation to tower crane safety
standards?
American Standards for Mechanical Equipment
American Safety Management Experts
Association of Structural Mechanics Engineers
American Society of Mechanical Engineers
,4. If a tower crane uses a rope with a nominal diameter of 1 inch, what should be
the minimum diameter of the load hoist drum to comply with safety
standards?
1 inch
18 inches
36 inches
12 inches
5. If a construction site is using a personnel platform over water, what safety
measures should be implemented to ensure compliance with OSHA
regulations, considering the exemption of PFDs?
Ensure that no employees are allowed on the platform.
Remove all safety equipment since PFDs are not required.
Only provide PFDs for employees who request them.
Implement rigorous training and safety protocols for fall prevention.
6. Describe the significance of the minimum design factor for wire rope slings in
crane operations.
The minimum design factor is irrelevant to crane operations.
The minimum design factor only applies to lifting equipment other
than wire rope slings.
The minimum design factor ensures that wire rope slings can safely
support loads without failure.
The minimum design factor is a guideline rather than a requirement.
7. According to Title 29, CFR 1910: Wire rope slings shall be immediately
removed from service if there are randomly distributed broken
, wires in one rope lay.

8. According to ASME B30.5, the load must not be lowered below the point
where there are full wraps of rope on the drum.

9. What percentage of their rated load must custom designed rigging hardware
be proof tested to according to OSHA 1926.251?
125%
50%
100%
75%
10. Which organization provides guidelines for conducting Load Tests on tower
cranes?
OSHA
ASME
ANSI
, ISO
11. If a crane operator is lifting a load with a two-way bridle at a horizontal angle
of 40 degrees, what potential risks could arise from this angle?
Increased risk of load slippage and instability during the lift.
The load will lift faster due to the angle.
No risks, as the load will remain stable regardless of the angle.
The operator will have better visibility of the load.
12. In a scenario where multiple lifts are happening simultaneously, how would
the first element of voice signals impact the safety of tower crane
operations?
It would help prevent confusion and ensure that the correct
operator responds to the signals.
It would have no impact on safety since all operators are trained.
It would only be necessary if the lifts were happening in different
locations.
It would complicate communication and increase the risk of
accidents.
13. If a tower crane's high-tensile bolt connection is found to have debris on the
bolt before torque application, what should be the next step in the safety
protocol?
Ignore the debris and proceed with the operation.
Clean the bolt thoroughly before proceeding with torque
application.
Replace the bolt without cleaning it.
