1. What is the primary purpose of a mobile crane’s load chart?
A) To measure wind speed
B) To determine maximum load capacity at various boom lengths
and angles
C) To check engine oil levels
D) To schedule maintenance
B) The load chart provides the operator with critical information on
the crane’s lifting capacities based on boom length, radius, and
configuration, ensuring safe operation.
2. Which of the following is a common hazard when operating a
mobile crane near power lines?
A) Falling objects
B) Electrocution
C) Tire punctures
D) Fuel spills
B) Cranes can contact overhead power lines, leading to serious
electrical hazards including electrocution, making awareness and
clearance crucial.
, 3. What is the purpose of outriggers on a mobile crane?
A) To lift heavier loads
B) To stabilize the crane during lifting operations
C) To extend the reach of the boom
D) To control speed
B) Outriggers provide a wider base and prevent tipping, enhancing
stability during lifts.
4. How often should a mobile crane undergo a formal inspection
according to OSHA standards?
A) Once every 5 years
B) Before each use and annually for detailed inspection
C) Only after an accident
D) Monthly
B) OSHA requires a pre-operation inspection before each use and a
thorough annual inspection to ensure all components are safe and
functioning.
5. What is the correct response if a crane begins to tip during a lift?
A) Accelerate the lift
B) Continue lifting cautiously
C) Lower the load immediately and stop operation
D) Sound the horn
C) Stopping and lowering the load immediately is critical to prevent a
complete tip-over and potential injuries.
6. Which factor most affects crane stability during lifting?
A) Operator’s weight
B) Load radius
C) Tire pressure
D) Crane color
, B) The load radius—the distance from the crane’s center of rotation to
the load—greatly influences tipping risk; larger radii reduce stability.
7. What is the main function of a boom angle indicator?
A) Measures wind speed
B) Displays boom angle to assist in safe lifting
C) Controls the crane engine
D) Measures load weight
B) A boom angle indicator helps operators maintain safe lifting angles
according to the load chart.
8. What should be done before moving a crane on public streets?
A) Raise the boom fully
B) Ensure load is secured, outriggers retracted, and route is clear
C) Ignore traffic signals
D) Open all crane doors
B) Safety procedures require that the boom be properly positioned,
outriggers retracted, and the route cleared before travel to prevent
accidents.
9. Which signal should the operator follow when performing a lift?
A) Hand signals from a qualified signal person
B) Verbal instructions from bystanders
C) GPS alerts
D) Personal judgment only
A) Operators must follow standardized hand signals from a qualified
signal person to ensure safe coordination.
10. What is the purpose of a load moment indicator (LMI)?
A) Measures fuel efficiency
B) Alerts the operator if the crane is approaching its lifting
capacity
