ALBERTA CRANE & HOISTING EQUIPMENT
OPERATOR Practice Exam Questions and
Answers with Rationales Latest Version
Question 1
Before operating any crane at the beginning of a shift, the operator's
FIRST responsibility is to:
A. Test the horn
B. Inspect the crane and review the logbook
C. Warm the engine for 30 minutes
D. Grease the boom
Correct Answer: B. Inspect the crane and review the logbook
Rationale
Pre-operational inspections are legally required and help identify defects
before equipment is used. Operators should examine:
• Structural components
• Hydraulic systems
• Wire ropes
• Hooks
• Safety devices
• Controls
• Previous maintenance records
Reviewing the inspection log ensures outstanding defects have been
addressed.
,Why the others are incorrect
• A: Testing the horn is only one inspection item.
• C: Engine warm-up alone does not verify safe operating condition.
• D: Lubrication may be required but is not the first responsibility.
Question 2
Which factor has the greatest effect on a crane's lifting capacity?
A. Operator experience
B. Boom angle and radius
C. Fuel level
D. Paint colour
Correct Answer: B. Boom angle and radius
Rationale
The farther the load is from the crane's center of rotation (greater radius),
the less weight the crane can safely lift.
Increasing radius:
• Reduces lifting capacity
• Increases overturning moment
• Places greater stress on structural components
Always consult the manufacturer's load chart.
Question 3
,What does the crane load chart primarily provide?
A. Engine specifications
B. Safe lifting capacities under various configurations
C. Hydraulic fluid capacity
D. Tire inflation pressures
Correct Answer: B. Safe lifting capacities under various
configurations
Rationale
The load chart tells operators:
• Maximum allowable loads
• Boom lengths
• Boom angles
• Operating radius
• Outrigger configurations
• Counterweight requirements
Operating beyond chart limits can result in crane overturn or structural
failure.
Question 4
The purpose of outriggers is to:
A. Increase travel speed
B. Improve fuel efficiency
C. Increase stability during lifting
, D. Reduce engine noise
Correct Answer: C. Increase stability during lifting
Rationale
Outriggers:
• Widen the crane's support base
• Transfer weight to the ground
• Reduce tipping hazards
• Improve lifting capacity when fully extended
Improperly deployed outriggers are a common cause of crane accidents.
Question 5
If the ground beneath an outrigger is soft, the operator should:
A. Continue lifting carefully
B. Use larger outrigger pads or cribbing
C. Retract the outriggers
D. Lift only lightweight loads
Correct Answer: B. Use larger outrigger pads or cribbing
Rationale
Soft ground can cause outrigger settlement and crane instability.
Proper cribbing:
• Spreads the load
• Prevents sinking
