1. The primary purpose of the tower crane’s load chart is to:
A. Estimate fuel consumption
B. Determine safe lifting capacities
C. Control wind loads
D. Adjust counterweights
Rationale: Load charts show safe lifting limits at different boom angles
and radii.
2. A crane operator should conduct a pre-operational inspection:
A. Weekly
B. Monthly
C. Daily before use
D. Only when required
Rationale: Daily inspections help identify defects that could cause
accidents.
3. The term “rated capacity” refers to:
A. Maximum engine power
B. Maximum load a crane can safely lift
C. Maximum height possible
D. Maximum wind speed allowed
Rationale: Rated capacity is the manufacturer’s safe load limit.
4. When operating in high winds, an operator should:
A. Ignore wind speed
B. Increase load
, C. Lower the load and suspend operation if needed
D. Lift faster
Rationale: Wind increases load swing and risk; safety requires lowering
load.
5. The purpose of the anti-two block device is to:
A. Increase lifting speed
B. Prevent hook block from contacting boom tip
C. Improve hoist efficiency
D. Reduce noise
Rationale: It prevents cable damage and boom tip collision.
6. Load radius affects lifting capacity because:
A. It increases engine load
B. It changes leverage on the crane
C. It doesn’t affect capacity
D. It affects tire wear
Rationale: Longer radii reduce safe lifting capacity due to torque.
7. The operator’s area of responsibility includes:
A. Fueling only
B. Cleaning the cab
C. Safe operation of the crane in assigned area
D. Supervising the whole site
Rationale: Operators are responsible for safe operation where they are
assigned.
8. Which signal means “Lower the load”?
A. Stop
B. Hand moving downward repeatedly
C. Move slowly
D. Raise boom
Rationale: Standard signals designate downward motion.
9. A crane’s boom deflection increases with:
A. Decreased load
B. Increased load and radius
C. Wind direction only
, D. Decreased height
Rationale: More load and longer radius cause more deflection.
10.Before lifting personnel, the operator must:
A. Increase speed
B. Ensure crane is rated for personnel lift
C. Reduce counterweight
D. Ignore wind limits
Rationale: Only cranes equipped and certified for personnel lifts may do
so.
11.A tag line is used to:
A. Measure load weight
B. Control the load from spinning
C. Steer the crane
D. Clean the hook
Rationale: Tag lines help stabilize a load.
12.The operator should use outriggers:
A. Only in rain
B. On all crane setups per manufacturer
C. Never
D. Only offshore
Rationale: Outriggers stabilize the crane according to specs.
13.The braking system must be capable of:
A. Ignoring loads
B. Holding and stopping the load safely
C. Running nonstop
D. Reducing engine heat
Rationale: Brakes must stop and hold loads safely.
14.Minimum required clearance from power lines is:
A. 1 foot
B. 5 feet
C. As specified by regulations based on voltage
D. None
Rationale: Regulations require safe distance based on voltage.
