During a complex hoisting operation in a densely built urban environment, a
NYC Master Rigger is required to relocate a large HVAC unit weighing several
tons from street level to the roof of an occupied building. Prior to the lift, the
rigger observes that the crane is positioned near underground utility
structures and that the proposed load path passes close to energized power
lines and adjacent structures. According to accepted rigging principles,
safety requirements, and the responsibilities of a Master Rigger, which
action should be taken first before authorizing the lift to proceed?
A. Begin the lift immediately because the crane operator is ultimately
responsible for all lifting decisions.
B. Increase the crane's operating speed to minimize the amount of time the
load remains suspended.
,C. Conduct a comprehensive assessment of crane setup conditions, load
weight verification, ground-bearing capacity, clearance hazards, and all site-
specific risks before approving the operation.
D. Proceed with the lift if the load appears stable after a short test pick
regardless of surrounding hazards.
C. Conduct a comprehensive assessment of crane setup conditions, load
weight verification, ground-bearing capacity, clearance hazards, and all
site-specific risks before approving the operation.
Rationale: A NYC Master Rigger is responsible for ensuring that lifting
operations are properly planned and safely executed. Before any hoisting
activity begins, critical factors such as load calculations, crane capacity,
supporting surface conditions, utility conflicts, power-line clearances, and
surrounding hazards must be evaluated. This systematic assessment helps
prevent crane instability, structural damage, electrocution hazards, and
load-control failures that could endanger workers and the public.
1. Before a critical lift involving a load near the crane’s maximum rated
capacity, what is the most important first step for a NYC Master
Rigger?
A. Estimate the load weight visually
B. Verify the exact load weight and compare it with the crane load chart
C. Extend the boom to maximum length
D. Increase hoist speed
,B. Verify the exact load weight and compare it with the crane load chart
Rationale: Accurate load determination and verification against the crane’s
rated capacity are essential to prevent overloading and potential crane
failure.
2. Which sling inspection finding requires immediate removal from
service?
A. Minor surface discoloration
B. Manufacturer tag present and legible
C. Broken wires exceeding allowable limits
D. Light dirt accumulation
C. Broken wires exceeding allowable limits
Rationale: Excessive broken wires significantly reduce sling strength and
create an unacceptable risk of failure.
3. What is the primary purpose of a lift plan?
A. Increase production speed
B. Reduce equipment costs
C. Identify hazards and establish safe lifting procedures
D. Eliminate the need for supervision
C. Identify hazards and establish safe lifting procedures
, Rationale: Lift plans help ensure safe execution by addressing load
characteristics, equipment selection, personnel responsibilities, and
hazards.
4. What is the safest action when wind speeds exceed allowable limits
during a lift?
A. Continue if the load is light
B. Increase tag line personnel
C. Suspend lifting operations
D. Increase boom angle
C. Suspend lifting operations
Rationale: Excessive wind can cause loss of load control, crane instability,
and structural stress.
5. Why are tag lines commonly used during hoisting operations?
A. To increase load weight
B. To control load rotation and movement
C. To replace rigging hardware
D. To increase crane capacity
B. To control load rotation and movement
Rationale: Tag lines allow personnel to guide suspended loads while
maintaining a safer distance.
6. What is the function of a crane load chart?
