1. Which agency is responsible for issuing Hoisting Machine Operator licenses in New York
City?
A. New York State Department of Labor
B. New York City Department of Buildings
C. Occupational Safety and Health Administration
D. Port Authority of New York and New Jersey
Answer: B
The New York City Department of Buildings (DOB) is responsible for issuing NYC Hoisting
Machine Operator licenses. The licensing requirements are established through the NYC
Construction Code and applicable DOB rules.
2. A crane operator is preparing to perform a lift when the wind begins increasing beyond
the manufacturer's permitted operating conditions. What should the operator do first?
A. Increase engine speed to stabilize the crane
B. Continue because the load is below rated capacity
C. Stop or suspend the lifting operation until conditions are safe
D. Reduce the load only after completing the lift
Answer: C
Wind can significantly affect crane stability, load control, and structural loading. The operator
should suspend operations when environmental conditions exceed established safe operating
limits.
3. What is the primary purpose of a crane's load chart?
A. To determine the maximum allowable load under specified operating conditions
B. To identify the crane's fuel consumption
C. To establish the operator's work schedule
D. To determine the color of the crane's signal lights
Answer: A
A load chart establishes the crane's rated capacity for specific configurations, including
factors such as boom length, radius, and equipment configuration.
,4. Before beginning a critical lift, which information is most important for the operator to
verify?
A. The crane's paint condition
B. The operator's total hours worked that week
C. The number of workers on the project
D. The load weight, radius, configuration, and applicable capacity
Answer: D
A safe lift requires verification that the planned load and operating configuration remain
within the crane's rated capacity and approved operating limits.
5. A load is positioned farther from the crane's center of rotation than originally planned.
What is the most likely effect?
A. Rated capacity generally decreases
B. Rated capacity automatically increases
C. Boom weight becomes irrelevant
D. Ground pressure becomes zero
Answer: A
As operating radius increases, crane capacity generally decreases because the overturning
moment increases. The operator must consult the applicable load chart.
6. What does the term "working radius" generally refer to during crane operations?
A. The crane's overall width
B. The distance from the crane's center of rotation to the load's center of gravity
C. The length of the operator's control lever
D. The distance between two outriggers
Answer: B
Working radius is measured from the crane's center of rotation to the applicable load
location, normally considering the load's center of gravity.
7. During setup, one outrigger is positioned over unstable soil. What is the safest response?
A. Extend the boom to counterbalance the crane
B. Place the load on the opposite side
C. Correct the ground-support condition before lifting
D. Increase the engine speed
Answer: C
Adequate ground support is fundamental to crane stability. An unstable outrigger location
must be corrected before the crane is placed under lifting load.
,8. Why are outrigger mats or suitable blocking used?
A. To increase engine horsepower
B. To reduce hydraulic pressure
C. To shorten the boom
D. To distribute outrigger loads over a larger supporting area
Answer: D
Mats and suitable blocking distribute concentrated outrigger reactions over a larger area,
reducing ground pressure and improving stability.
9. What should an operator do if the load weight is unknown before a planned lift?
A. Estimate the weight from the load's appearance
B. Determine the actual or reliably established weight before lifting
C. Lift slowly to determine whether the crane can handle it
D. Ask a nearby worker to guess the weight
Answer: B
A crane must not be operated based on an unreliable load-weight estimate. The load weight
must be established sufficiently to determine whether the planned lift is within capacity.
10. What is the main danger of side loading a crane boom?
A. It can impose forces for which the boom was not designed
B. It always increases rated capacity
C. It prevents the load from swinging
D. It reduces ground pressure
Answer: A
Crane booms are primarily designed for loads applied within their intended operating
geometry. Side loading can create damaging stresses and instability.
11. A signalperson gives a stop signal while the operator is hoisting. What should the
operator do?
A. Ignore the signal unless the load is already moving
B. Continue until the load reaches the intended height
C. Stop the crane movement promptly and safely
D. Ask another worker whether the signal is valid
Answer: C
A stop signal must be acted upon immediately when received from an authorized
signalperson. Stopping safely prevents a developing hazard from becoming an incident.
, 12. When should an operator refuse to proceed with a lift?
A. When the lift is routine
B. When the load is properly rigged
C. When the weather is favorable
D. When unsafe conditions cannot be corrected or adequately controlled
Answer: D
Professional operators have a responsibility to stop unsafe operations. Production pressure
never overrides established safety requirements.
13. Which condition most directly increases overturning risk?
A. A larger operating radius
B. A clean windshield
C. Lower engine noise
D. A freshly painted boom
Answer: A
Increasing radius increases the overturning moment and normally reduces the crane's
allowable capacity.
14. What is the purpose of a crane's rated capacity indicator or limiter when properly
installed and functioning?
A. To replace the operator's judgment
B. To provide information or warning concerning operating capacity and limits
C. To determine employee wages
D. To eliminate the need for load charts
Answer: B
Capacity systems provide critical operational information or warnings, but they do not
replace the operator's responsibility to understand the load chart and operating limitations.
15. A crane operator notices hydraulic oil leaking from a boom cylinder before a lift. What
is the appropriate action?
A. Continue if the leak appears small
B. Increase hydraulic pressure
C. Stop and report the defect for evaluation and correction
D. Cover the leak with tape and continue
Answer: C
Hydraulic leakage can indicate a failure that affects crane control or structural support. The
equipment should be taken out of service as appropriate until the condition is evaluated.
