Looking for NCCCO practice questions you can try right now? Below are 10 exam-style questions with answers and short explanations. They cover the topics that trip up most candidates: load charts, radius, rigging, signals and site set-up.
These are original practice questions for study purposes, not real exam questions.
10 NCCCO-Style Practice Questions
1. What is "load radius"?
A) Length of the boom B) Horizontal distance from the center of rotation to the center of the hanging load C) Height of the hook
Answer: B. Capacity is read from the load chart using radius, not boom length.
2. If you raise the boom angle (and nothing else changes), what happens to the radius and capacity?
A) Radius decreases, capacity generally increases B) Radius increases, capacity increases C) No change
Answer: A. A steeper boom brings the load closer to the crane.
3. Which document gives the crane's rated capacity for a specific configuration?
A) The site sign-in sheet B) The manufacturer's load chart C) The rigger's gloves
Answer: B. Always use the load chart for the exact configuration (boom length, outrigger set-up, counterweight).
4. As the angle between a sling leg and the horizontal gets smaller, tension in each leg:
A) Decreases B) Stays the same C) Increases
Answer: C. Low sling angles multiply the force on each leg, so check the rated capacity at that angle.
5. What should the operator do if the signal is unclear?
A) Guess B) Stop and clarify before moving the load C) Swing slowly
Answer: B. Unclear signal = stop. Any person can give an emergency stop, and the operator must obey it.
6. Before lifting, outriggers should be:
A) Set exactly as the load chart configuration requires B) Partly extended to save time C) Left retracted on firm ground
Answer: A. The chart you use must match how the crane is actually set up.
7. Which item must be deducted from the load chart capacity?
A) Everything on the hook, including rigging, hook block and any other attached items B) Only the load C) Nothing
Answer: A. All weight below the boom point counts toward the load.
8. A sling is visibly damaged and its tag is missing. You should:
A) Use it for light loads B) Remove it from service C) Tape it
Answer: B. When in doubt, take it out.
9. What is the main risk of a side load on the boom?
A) Faster hoisting B) Structural damage and possible boom failure C) Better stability
Answer: B. Cranes are designed for loads that hang vertically.
10. When wind increases, the operator should:
A) Ignore it if the load is heavy B) Follow manufacturer wind limits and stop lifting if the load becomes uncontrollable C) Lift faster
Answer: B. Wind affects both load control and crane stability.
How to Use Practice Questions Properly
- Don't just memorize answers. Ask why the answer is right.
- Redo the questions you missed after 24 hours.
- Practice load chart reading daily; it is a skill, not a fact.
- Mix topics so you don't only study your favorite section.
