NCCCO RIGGER CERTIFICATION
LEVEL II
Exam Elaborations Questions &
Answers

, A Level II rigger is planning a multi-crane lift of a long steel truss. The primary technical concern
when synchronizing cranes is:
A. Matching paint color of cranes
B. Load sharing and load path control between cranes
C. Increasing wind resistance intentionally
D. Eliminating the need for a lift plan
Answer: B
Rationale: Multi-crane lifts require precise load sharing to prevent overloading either crane and to
maintain stability of the load path.
During a critical lift, a rigger observes that one crane is taking slightly more load due to uneven
boom angles. What is the correct response?
A. Ignore if within 10% difference
B. Immediately halt and rebalance load distribution
C. Increase speed of lift
D. Add more rigging hardware mid-lift
Answer: B
Rationale: Unequal load distribution in multi-crane lifts creates instability and must be corrected
immediately.
True/False: A Level II rigger is expected to understand load moment calculations and their impact
on crane stability.
Answer: True
Rationale: Advanced rigging requires understanding of torque and moment effects on crane
configurations.
Fill in the blank: The point where a crane is most likely to tip due to load extension is called the
________.
Answer: tipping point
Rationale: It defines instability threshold in crane operations.
A truss is being lifted using a spreader beam, but deflection is observed beyond manufacturer
limits. This indicates:
A. Normal behavior
B. Overloading or improper configuration
C. Improved structural efficiency
D. Reduced load on crane
Answer: B
Rationale: Excessive deflection indicates overstress or improper application.
True/False: Tag lines are primarily used to control load rotation and prevent uncontrolled swing.
Answer: True
Rationale: Tag lines stabilize suspended loads during movement.
Fill in the blank: The calculation used to determine force distribution in multi-leg slings is based on
________ analysis.
Answer: vector
Rationale: Forces in slings are resolved using vector mechanics.
A rigger uses a sling configuration where the angle is below 30 degrees from horizontal. What is
the primary hazard?
A. Increased crane speed
B. Excessive tension in sling legs
C. Reduced load weight
D. Improved load stability
Answer: B
