1. Under NYC rules, the primary responsibility of a Hoisting Machine
Operator Class C license holder is to:
A. Perform structural engineering calculations for crane foundations
B. Inspect building plans for zoning compliance
C. Operate approved hoisting equipment safely and in accordance with
applicable regulations
D. Certify welding procedures on construction sites
C. Operate approved hoisting equipment safely and in accordance with
applicable regulations
The Class C license authorizes the operator to run designated hoisting
equipment and requires compliance with safety regulations, manufacturer
requirements, and site-specific procedures.
2. Before beginning operation of a hoisting machine at the start of a shift,
the operator should first:
,A. Immediately place the equipment under load
B. Conduct required pre-operational inspections and functional checks
C. Remove all warning labels from the controls
D. Increase engine speed to maximum RPM
B. Conduct required pre-operational inspections and functional checks
Pre-operational inspections help identify defects, unsafe conditions, or
malfunctions before equipment is placed into service.
3. The load chart provided by the manufacturer is primarily used to
determine:
A. Employee payroll classifications
B. Fuel consumption rates
C. Maximum allowable lifting capacities under specified conditions
D. Building occupancy limits
C. Maximum allowable lifting capacities under specified conditions
Load charts establish safe lifting capacities based on boom length, radius,
configuration, and other operating factors.
4. If a load exceeds the rated capacity shown on the load chart, the
operator should:
A. Proceed if the load is only slightly above capacity
B. Lift the load slowly to reduce risk
C. Add more counterweight without approval
D. Refuse the lift until it can be performed within rated limits
D. Refuse the lift until it can be performed within rated limits
Exceeding rated capacity creates a significant risk of structural failure,
tipping, and serious injury.
, 5. Wind conditions are important during hoisting operations because
wind can:
A. Increase fuel efficiency
B. Reduce communication requirements
C. Affect load stability and crane performance
D. Eliminate the need for tag lines
C. Affect load stability and crane performance
Wind can cause loads to swing, increase load forces, and reduce overall
operational stability.
6. A signal person should be:
A. Ignored whenever the operator has a clear view
B. Properly qualified and understood by the operator
C. Selected randomly from the work crew
D. Responsible for equipment repairs
B. Properly qualified and understood by the operator
Safe lifting operations depend on clear communication between qualified
signal persons and operators.
7. When hand signals are being used, the operator should obey:
A. Any signal given by spectators
B. Only signals from truck drivers
C. Signals from the designated signal person except emergency stop signals
from anyone
D. Signals from the nearest worker
C. Signals from the designated signal person except emergency stop signals
from anyone
, Emergency stop signals must be obeyed regardless of who gives them
because safety takes priority.
8. The purpose of outriggers on a crane is to:
A. Increase travel speed
B. Improve machine stability during lifting operations
C. Reduce engine temperature
D. Store rigging equipment
B. Improve machine stability during lifting operations
Outriggers enlarge the support base and help prevent tipping during lifts.
9. Before setting outriggers, the operator should verify:
A. Ground conditions are capable of supporting imposed loads
B. Employees have left for lunch
C. The boom is fully extended
D. Fuel tanks are empty
A. Ground conditions are capable of supporting imposed loads
Unstable or inadequate ground conditions can lead to crane settlement,
instability, or overturning.
10. The operating radius of a crane refers to:
A. The length of the wire rope
B. The distance from the center of rotation to the load center
C. The diameter of the tire
D. The height of the operator’s cab
B. The distance from the center of rotation to the load center
Operating radius is a critical factor affecting crane lifting capacity.
11. A sudden increase in operating radius generally results in:
