1. What is the primary responsibility of a crane operator before
beginning a lifting operation?
a. Increase the crane's lifting speed
b. Verify the load weight only
c. Ensure the crane and lifting operation can be conducted safely
d. Allow the signal person to make all safety decisions
Rationale: The operator is responsible for conducting the lift safely
within the crane's rated capacity and operating limitations. This
includes checking the equipment, understanding the load, confirming
proper setup, and following applicable procedures and signals.
2. What document is most important for determining the maximum
rated capacity of a crane for a particular configuration?
,a. Daily attendance sheet
b. Load chart
c. Purchase invoice
d. Operator's personal logbook
Rationale: The load chart specifies the crane's rated capacity for
different boom lengths, radii, configurations, counterweight
arrangements, and other conditions. The operator must use the
correct chart for the actual crane configuration.
3. What does load radius generally mean in crane operations?
a. The length of the boom
b. The distance between the outriggers
c. The horizontal distance from the crane's center of rotation to the
load's center of gravity
d. The height of the hook above the ground
Rationale: Load radius is a critical factor in determining crane
capacity. As the operating radius increases, the crane's lifting capacity
generally decreases because the load creates greater overturning
moment.
4. Before lifting a load, why should the operator determine its
weight?
,a. To determine the required fuel level
b. To select the operator
c. To verify that the load is within the crane's rated capacity
d. To determine the color of the signal flags
Rationale: Knowing the load weight is essential for comparing the
planned lift against the crane's load chart. The operator should also
account for the weight of rigging devices and other attachments
included in the suspended load.
5. What is the safest action if the operator cannot determine the
weight of a load with reasonable confidence?
a. Lift it quickly
b. Estimate the weight and proceed
c. Have the signal person guess
d. Obtain reliable weight information before making the lift
Rationale: Guessing the weight can result in overloading, structural
damage, or loss of stability. Reliable load information should be
obtained before the crane is committed to the lift.
6. What is the purpose of a pre-operation inspection?
a. To increase the crane's rated capacity
b. To identify conditions that could affect safe operation
, c. To eliminate the need for maintenance
d. To determine the operator's pay rate
Rationale: Inspections help identify damaged, worn, loose, leaking, or
malfunctioning components before the crane is placed into service.
Deficiencies that affect safe operation must be addressed
appropriately.
7. Which condition should cause an operator to stop and evaluate
the crane before continuing?
a. Clean windows
b. Normal engine temperature
c. A damaged wire rope
d. Properly inflated tires
Rationale: Damaged wire rope can fail under load and create a
serious struck-by or dropped-load hazard. Wire rope must be
inspected and removed from service when its condition does not meet
applicable requirements.
8. What is the main purpose of outriggers on a crane?
a. Increase engine horsepower
b. Reduce hook weight
