INTRODUCTION
This 150-question practice examination is designed for candidates preparing for
the New York State Crane Operator Class B Written Examination. It emphasizes the
technical knowledge, regulatory judgment, load-chart interpretation, rigging
principles, operational safety, inspection requirements, communication, stability,
and hazard recognition expected of a professional crane operator. The questions
are intended for experienced operators, apprentices, supervisors, mechanics,
safety professionals, and candidates pursuing crane-operator qualification. The
testbank contains 150+ questions and answers with a rationale, progressing from
advanced application to difficult scenario-based decision-making. Students should
expect realistic licensing-level problems requiring analysis rather than
memorization. (purchase and instantly get a downloadable and editable pdf)
QUESTION 1
Question 1
A Class B crane operator is preparing to lift a load whose weight is known, but the
boom configuration differs from the configuration shown in a commonly used
reference chart. What should determine the permissible capacity?
A. The operator's experience with similar lifts
B. The maximum capacity stamped on the crane
,C. The applicable manufacturer's load chart for the actual configuration
D. The capacity used on the previous shift
Correct Answer: C
Explanation: Rated capacity depends on the actual crane configuration, radius,
boom arrangement, parts of line, attachments, and other chart variables.
QUESTION 2
Question 2
During a lift, the operator notices that the load radius has increased because the
load has swung away from the crane. What is the principal concern?
A. The engine will necessarily overspeed
B. The crane may experience a substantial reduction in rated capacity and stability
margin
C. The hook will automatically become overloaded
D. The boom angle will become irrelevant
Correct Answer: B
Explanation: Increasing radius increases overturning moment and can
substantially reduce allowable capacity.
QUESTION 3
Question 3
A crane's load chart lists capacities for several boom lengths and operating radii.
The operator is between two listed radii and wants to determine the allowable
capacity. Which approach is safest?
A. Interpolate only when permitted by the manufacturer's instructions
B. Use the higher capacity because the difference is small
C. Average the two capacities automatically
D. Use the capacity corresponding to the shortest radius
Correct Answer: A
Explanation: Capacity must be determined according to the manufacturer's
chart and instructions; assumptions that increase capacity are unacceptable.
,QUESTION 4
Question 4
Which factor most directly affects a crane's overturning moment during a
stationary lift?
A. Paint condition
B. Load weight and horizontal operating radius
C. Engine coolant temperature
D. Cab temperature
Correct Answer: B
Explanation: Overturning moment is fundamentally related to force and its
horizontal distance from the tipping axis.
QUESTION 5
Question 5
A load weighs 8,000 lb and is positioned at a 20-ft radius. Ignoring other forces,
what is the load moment?
A. 160 lb-ft
B. 400 lb-ft
C. 16,000 lb-ft
D. 160,000 lb-ft
Correct Answer: D
Explanation: Load moment equals weight multiplied by radius: 8,000 × 20 =
160,000 lb-ft.
QUESTION 6
Question 6
A crane operator discovers that the actual load weight is greater than the
estimated weight used during lift planning. What should occur before continuing?
A. Increase engine speed
B. Continue if the difference is less than 10 percent
C. Reevaluate the lift using the actual or appropriately verified weight
D. Reduce the number of signal persons
, Correct Answer: C
Explanation: A changed load weight can invalidate the planned capacity and
must be evaluated before lifting.
QUESTION 7
Question 7
Which statement best describes gross capacity versus net lifting capacity?
A. They are always identical
B. Gross capacity may include deductions required for attachments and reeving
components
C. Net capacity always exceeds gross capacity
D. Net capacity is based only on engine horsepower
Correct Answer: B
Explanation: The allowable payload can be reduced by deductions such as hook
blocks, headache balls, rigging, and other applicable equipment.
QUESTION 8
Question 8
The crane is level when unloaded, but the ground begins to settle beneath one
outrigger during a lift. What is the most appropriate immediate response?
A. Continue slowly
B. Increase the boom angle
C. Stop the operation and stabilize/reassess the crane
D. Swing rapidly toward the opposite side
Correct Answer: C
Explanation: Differential settlement can alter geometry, stability, and load
distribution and must be corrected before proceeding.
QUESTION 9
Question 9
Why is a crane's level condition important?
