1. A rigging supervisor overseeing a multi-crane lift determines that the
load weight is close to the rated capacity of the planned crane
configuration. What is the most appropriate first action before
approving the lift plan?
A. Proceed with the lift using reduced swing radius
B. Request a higher rated hook block to increase capacity
C. Recalculate load weight, rigging configuration, and apply updated
safety factors before approval
D. Delegate decision-making authority to the crane operator
The supervisor must verify all load calculations and rigging
parameters to ensure the lift remains within safe operational limits
before any approval is granted.
2. During a critical lift, wind speeds begin to increase beyond the
threshold specified in the lift plan. What should the rigging supervisor
do?
A. Continue the lift if the load is already airborne
B. Suspend lifting operations until wind conditions return within
acceptable limits
C. Shift the load more quickly to reduce exposure time
, D. Increase crane counterweight to stabilize the load
Operations must be stopped because wind conditions directly affect
load stability and exceedance of thresholds introduces unacceptable
risk.
3. Which factor is most important when selecting synthetic slings for a
sharp-edged load?
A. Color coding of the sling
B. Manufacturer branding
C. Length of the sling only
D. Use of protective padding or edge protection to prevent sling
damage
Sharp edges can cut or weaken synthetic slings, making protective
measures essential for safe rigging.
4. A supervisor observes that a rigger is using a sling with visible abrasion
and broken fibers. What is the correct action?
A. Allow use if load is light
B. Rotate the sling to hide damaged areas
C. Remove the sling from service immediately
D. Tag it for future inspection
Damaged slings must be removed from service immediately because
they cannot be considered structurally reliable.
5. What is the primary purpose of a rigging plan in heavy lift operations?
A. To assign payroll responsibilities
B. To document crane rental agreements
C. To reduce insurance premiums
D. To ensure safe, controlled, and coordinated lifting operations
through detailed planning of equipment and procedures
A rigging plan ensures all elements of the lift are analyzed and
controlled to minimize operational risk.
6. When two cranes are used to lift a single load, what is the most critical
supervisory concern?
A. Matching crane paint colors
B. Equal operator experience levels
C. Load distribution and synchronized movement between cranes
D. Using identical crane models only
, Dual-crane lifts require precise coordination to ensure balanced load
sharing and prevent overload.
7. A load exceeds the crane’s chart capacity at a specific boom angle.
What is the appropriate response?
A. Proceed slowly with extra tag lines
B. Increase hoist speed to reduce stress time
C. Adjust the crane configuration or select a higher-capacity crane
D. Reduce communication between crew to avoid confusion
Operating beyond crane capacity is unsafe; configuration changes or
equipment substitution is required.
8. What is the most important reason for conducting a pre-lift meeting?
A. To assign overtime shifts
B. To discuss company policies
C. To review payroll details
D. To ensure all personnel understand the lift plan, hazards, and
communication protocols
Pre-lift meetings align the entire team on safety, responsibilities, and
operational steps.
9. Which condition most directly affects crane stability during lifting
operations?
A. Operator clothing color
B. Site supervisor experience
C. Ground bearing capacity beneath outriggers
D. Number of radios on site
Crane stability depends heavily on ground conditions supporting
outriggers and load distribution.
10. What is the correct response if a load begins to swing
uncontrollably during lifting?
A. Increase hoist speed
B. Add more riggers to stabilize mid-air
C. Stop movement and allow controlled stabilization before
proceeding
D. Reverse crane rotation rapidly
Sudden stopping and stabilization prevent amplification of swing and
reduce accident risk.
