NCCCO Final Exam Study Guide 2026 | Complete Review |
Graded A+
1. What is the primary purpose of outriggers on a crane?
To improve maneuverability.
To increase stability and tipping capacity.
To lift heavier loads.
To reduce fuel consumption.
2. What does the term 'operating radius' refer to in crane operation?
The maximum height a crane can lift a load.
The area within which a crane can operate.
The total weight a crane can safely lift.
The distance from the center of rotation of the crane to the center
of the load being lifted.
3. If a crane operator notices that one outrigger float is not fully supported,
what immediate action should they take to ensure safety?
The operator can continue operations as long as the load is light.
The operator should stop operations and adjust the outrigger to
ensure it is fully supported.
The operator should ignore it if the crane seems stable.
The operator should only report it after the shift.
4. Describe how outriggers contribute to the overall safety of crane operations.
Outriggers help in the transportation of the crane.
, Outriggers allow the crane to lift more weight without any additional
safety measures.
Outriggers distribute the weight of the crane and increase its base,
reducing the risk of tipping.
Outriggers are used solely for aesthetic purposes.
5. Timber blocking placed under the tips of the tracks on a crawler crane will?
Decrease the rated capacity of the crane.
Will not change anything.
Increase the rated capacity of the crane.
Make the crane more stable.
6. When performing duty cycle operations, the crane must be de-rated by:
75%
20%
10%
50%
7. What is one reason crane manufacturers require reductions in capacity for
duty cycle work?
To improve fuel efficiency
To reduce maintenance costs
To ensure safety during operation
To increase the crane's speed
,8. If a crawler crane is operating on soft ground and is moved to a construction
site with hard ground, what considerations should the operator take into
account regarding load capacity?
The load capacity remains unchanged regardless of ground type.
The operator can increase the load capacity without any assessment.
The operator should reassess the load capacity as it may increase
due to higher ground bearing pressure.
The load capacity will decrease and should be reduced immediately.
9. Load chart capacities for on-outrigger lifting do not exceed .
65 percent of the tipping loads
95 percent of the tipping loads
85 percent of the tipping loads
75 percent of the tipping loads
10. Describe how the type of ground affects the stability of a crawler crane.
The type of ground has no effect on crane stability.
Hard ground provides better stability and increases ground
bearing pressure, while soft ground may lead to instability.
Soft ground enhances stability and reduces ground bearing pressure.
Both soft and hard ground equally support crane stability.
11. If a crane operator is preparing to lift a load on uneven ground, what
blocking or cribbing procedures should they implement according to OSHA
and ASME standards?
Only use blocking if the load is over a certain weight.
, Use appropriate blocking or cribbing to level the crane and
distribute the load evenly.
Cribbing is not necessary if the ground appears stable.
Lift the load without any blocking or cribbing to save time.
12. If a crane operator lacks knowledge in one of the four ASME knowledge
areas, what potential risks could arise during crane operation?
Increased risk of accidents and unsafe operation.
Enhanced understanding of load capacities.
No impact on crane operation.
Improved efficiency and productivity.
13. If a truck crane with no front mounted outrigger is attempting a pick over the
front, the crane's center of rotation will move:
closer to the tipping axis
further from the tipping axis
depends on the load dimentions
stay the same
14. Describe the safety precautions that should be taken when working near
overhead energized power lines.
Materials should be kept clear of the area to prevent electrical
hazards.
Materials can be stacked to maximize space.
Materials can be placed directly under the lines if they are non-
conductive.
