NCCCO Crane Operator Questions & Answers 2026 | High-
Yield Review | Graded A+
1. Describe the significance of the load chart capacities that are distinguished in
bold type and marked with an asterisk.
These capacities are only relevant for training purposes and not for
actual operations.
These capacities represent the maximum load that can be lifted under
any circumstances.
These capacities indicate that the load limits are contingent upon
specific conditions or limitations that must be adhered to for safe
operation.
These capacities are the same for all crane types regardless of
conditions.
2. According to ASME B30.5, when working around power lines of more than
750kV, how much clearance is generally required from any part of the crane
and its load?
25 ft.
45 ft.
35 ft.
30 ft.
3. Discuss why lifts exceeding 75% of a crane's capacity are classified as critical
lifts.
Lifts exceeding 75% of a crane's capacity are classified as critical
lifts because they pose a higher risk of instability and potential
failure.
, Lifts exceeding 75% of a crane's capacity are classified as critical lifts
since they require a different type of crane.
Lifts exceeding 75% of a crane's capacity are classified as critical lifts
due to the need for additional crew members.
Lifts exceeding 75% of a crane's capacity are classified as critical lifts
because they are always performed outdoors.
4. What should be used to prevent sling damage when lifting sharp angled
objects
Softener
A fork lift
Hardener
A double wrap basket
5. Max wear allowed on sheave
Nominal rope diameter +/- 2.5%
Nominal rope diameter +/- 5%
Nominal rope diameter +/- 1%
Nominal rope diameter +/- 2%
6. Describe how the outriggers affect the stability and working area chart of a
telescopic boom truck.
Outriggers are only necessary for lifting heavy loads.
Outriggers limit the height of the boom and reduce the load capacity.
Outriggers provide stability and allow for a larger working area by
distributing the weight of the crane.
, Outriggers do not impact the working area chart.
7. What is the recommended material to use as a softener for slings when they
come into contact with sharp edges?
Plastic
Steel
Padding
Rubber
8. What is the primary consequence of rapid hoist acceleration on hook loads?
It has no effect on hook loads.
It stabilizes the hook load.
It can increase the hook load significantly.
It decreases the hook load.
9. Describe the significance of the D/d ratio in ensuring crane stability during
operations.
The D/d ratio indicates the maximum load capacity of the crane.
The D/d ratio helps assess the stability of the crane by comparing
the distances involved, ensuring that the crane can safely lift the
load without tipping over.
The D/d ratio is used to determine the speed of the crane's operation.
The D/d ratio measures the height of the crane's lift.
10. A stationary load is:
gross
, static
dynamic
symmetrical
11. Describe the importance of identifying hazards and restrictions on a
construction site.
Identifying hazards helps in maximizing load capacity.
Identifying hazards is irrelevant to crane operation.
Identifying hazards and restrictions is crucial for ensuring safety
and compliance with regulations.
Identifying restrictions is only necessary for crane operators.
12. What is the correct minimum diameter of any sheave or drum in contact with
hoist rope?
20x the diameter of the rope
no minimum is required if the ropes are slung over a secondary
sheave
40x the diameter of the rope
no minimum is required if the ropes are slung over a deflector sheave
13. Of the following conditions, what would most likely indicate core failure in
rotation resistant wire rope?
core protrusion
shiny wires
core reduction
broken outside wires
