INTRODUCTION
This practice examination prepares candidates for the New York City Class A
Hoisting Machine Operator written examination and focuses on advanced crane
operation, load charts, stability, rigging, inspections, safety, regulations, and
professional judgment. It is designed for experienced crane operators, apprentices,
supervisors, safety professionals, and candidates preparing for professional
licensing or certification. The questions emphasize realistic operating scenarios
rather than simple memorization and require application of technical principles
under changing conditions. This study resource contains 150+ questions and
answers with concise rationales to reinforce understanding and decision-making.

QUESTIONS 1–150
Question 1
A Class A operator is assigned a mobile crane whose boom, including its jib
extension, will measure 198 ft during the lift. Which factor is most important when
determining whether the Class A license scope is applicable?
A. The actual weight being lifted
B. The manufacturer's maximum possible boom length
C. The actual boom and extension configuration used during the operation
D. The crane's maximum hoisting speed
, Correct Answer: C
Explanation: License applicability depends on the configuration actually being
operated. For Class A purposes, the boom and applicable extensions must
remain within the permitted length.
Question 2
A crane has a manufacturer's maximum rated capacity of 60 tons, but the planned
lift is only 40 tons. Which conclusion is most accurate for NYC HMO classification?
A. A lower class is acceptable because the planned load is below 50 tons
B. The operator classification is determined by the crane's manufacturer's rated
capacity
C. The operator classification depends only on radius
D. The classification can be selected by the site supervisor
Correct Answer: B
Explanation: The manufacturer's rated capacity is relevant to license
classification; reducing the actual lifted load does not change the machine's
rated-capacity classification.
Question 3
During setup, the operator discovers that one outrigger will be positioned over
recently excavated backfill. What is the best professional response?
A. Increase counterweight
B. Extend the boom before loading the outrigger
C. Verify that the supporting surface is adequate before loading the crane
D. Proceed if the soil appears visually compacted
Correct Answer: C
Explanation: Crane stability depends on adequate ground support. Visual
appearance alone is insufficient where disturbed or recently excavated soil is
involved.
Question 4
A load chart indicates different capacities for several boom lengths at the same
radius. Why?
,A. Boom length affects crane geometry and stability
B. Longer booms always weigh less
C. Load charts are intentionally inconsistent
D. Radius becomes irrelevant with longer booms
Correct Answer: A
Explanation: Boom length changes leverage, structural loading, geometry, and
often machine stability, so rated capacity can change substantially.
Question 5
The operator wants to increase lifting capacity by reducing the working radius.
What principle is being applied?
A. Reduced radius generally increases the allowable rated load
B. Reduced radius eliminates structural limitations
C. Reduced radius makes ground conditions irrelevant
D. Reduced radius automatically permits overload
Correct Answer: A
Explanation: Within the manufacturer's configuration limits, shorter working
radius generally improves capacity because overturning moment decreases.
Question 6
A load weighs 18,000 lb. The rigging assembly weighs 1,200 lb, and a lifting
attachment weighs 800 lb. What gross load should be considered?
A. 18,000 lb
B. 19,200 lb
C. 19,800 lb
D. 20,000 lb
Correct Answer: D
Explanation: The crane must account for the total suspended load: 18,000 +
1,200 + 800 = 20,000 lb.
Question 7
A boom crane is operating at a radius where the load chart permits 24,000 lb. The
calculated gross suspended load is 23,500 lb. A 1,000-lb accessory is then added.
What should the operator do?
, A. Proceed because the original load was below capacity
B. Proceed because accessories are excluded
C. Recalculate and recognize that the revised load exceeds capacity
D. Increase engine speed
Correct Answer: C
Explanation: The accessory increases gross load to 24,500 lb, exceeding the
24,000-lb rated capacity.
Question 8
Which condition most directly increases overturning moment?
A. Decreasing radius
B. Increasing radius
C. Reducing load weight
D. Lowering the hook without load
Correct Answer: B
Explanation: Overturning moment is strongly influenced by load and horizontal
distance from the tipping axis; increasing radius increases moment.
Question 9
A crane's load chart specifies capacity at a particular radius. The operator
estimates the radius visually and begins the lift. What is the primary deficiency?
A. The engine has not reached operating temperature
B. The actual operating radius has not been adequately established
C. The boom should always be fully extended
D. Visual estimation is always prohibited during operation
Correct Answer: B
Explanation: Accurate radius is essential to selecting the correct load-chart
capacity. An inaccurate estimate can result in an overload.
Question 10
A crane is positioned on a slope outside the manufacturer's permitted operating
conditions. Which action is most appropriate?
A. Add counterweight
B. Increase lifting speed
