NCCCO Tower Crane Exam 2026 | Questions & Verified
Answers | Latest Update | Graded A+
1. What does ASME B30.3 state about the operation of cranes by maintenance
personnel?
Maintenance personnel are permitted to operate the crane only
when they are specifically trained and authorized.
Maintenance personnel can operate the crane if they have a general
understanding of its functions.
Maintenance personnel can operate the crane at any time.
Maintenance personnel are never allowed to operate the crane.
2. Why must wire rope be lubricated?
To help protect it against corrosion and wear.
So it stays cool.
ASME requires it.
To help prevent sheave wear.
3. Describe the significance of the broken wire limit in six rope diameters for the
safety of tower crane operations as per ASME B30.3.
The limit allows for more flexibility in rope usage without
compromising safety.
The limit of 2 broken wires in six rope diameters is crucial for
ensuring the integrity and safety of the crane's lifting operations.
The limit is only applicable to older crane models.
The limit is irrelevant as long as the crane is inspected regularly.
,4. What is the primary purpose of conducting a load test on a tower crane?
To measure the crane's travel speed.
To ensure the crane can safely handle the specified load.
To check the crane's aesthetic appearance.
To evaluate the operator's skills.
5. What is the standard elongation percentage for high tensile bolts during
tightening?
A fixed length of 5 mm
A length equal to the diameter of the bolt
A specified percentage of the bolt's original length
No elongation is allowed
6. Who is responsible for the erection of a self erecting tower crane?
A qualified person
The crane operator
Any construction worker
The site supervisor
7. If a tower crane is used in heavy service conditions and the frequent
inspections are not conducted as required by ASME B30.3, what potential
risks could arise?
Enhanced performance of the crane
Increased risk of accidents and equipment failure
Reduced maintenance costs
, Improved operational efficiency
8. If a construction site has a personnel platform designed for two occupants
and three workers need to use it simultaneously, what should the site
manager do to comply with OSHA regulations?
Allow all three workers to use the platform at once since they are
trained.
Restrict the use of the platform to two occupants and schedule the
third worker for a later time.
Use the platform for one worker at a time to ensure safety.
Increase the weight limit of the platform to accommodate three
occupants.
9. What is the required rating for high tensile strength nuts used in bolt
connections for tower sections?
ASTM A194 Grade 2H
ASTM A563
ASTM A325
ASTM A307
10. If a construction site requires a heavy load to be lifted but there are multiple
access routes available, what should be evaluated before deciding to use a
tower crane?
The weather conditions on the day of operation.
The availability of crane operators.
The practicality of using alternative methods to perform the work.
The type of load being lifted.
, 11. When should a tagline be used during lifting operations?
only when lifting the load to extreme heights
when the supervisor approves their use
to prevent the load from swinging or rotating
when lifting a load over or near electrical transmission lines
12. If a tower crane operating under light service conditions has not undergone
a frequent inspection for two months, what potential risks could arise from
this oversight?
Improved operational efficiency and safety.
Reduced maintenance costs.
Increased risk of equipment failure and safety hazards.
No risks, as inspections are not critical.
13. If the hook height of a crane is increased to 400 feet, what adjustments
should be made regarding the hydraulic top climbing unit's position based
on chart B?
It should be moved to the base of the crane.
The hydraulic top climbing unit should be positioned at the top of
the crane.
It should be removed entirely.
It should remain at the same position as for 350 feet.
14. If a crane is using a load hoist rotation resistant wire rope with a design
factor of 5:1, what would be the maximum safe load if the wire rope is rated
for 10,000 pounds?
