1. Which of the following is the primary function of a tag line during a lift?
A. Support the load weight
B. Measure load tension
C. Control load rotation and swing
D. Reduce crane boom stress
Rationale: Tag lines are used to control the rotation and swing of a load to
ensure safe positioning.
2. What is the minimum proof test load for a wire rope sling rated at 5 tons?
A. 2,500 lbs
B. 5,000 lbs
C. 10,000 lbs
D. 15,000 lbs
Rationale: Proof test load is typically twice the rated load to ensure the
sling can handle expected forces safely.
3. When using synthetic web slings, what must be avoided?
A. Protecting the sling from sharp edges
B. Exposing to heat or chemical damage
C. Inspecting before use
D. Using correct hitch type
, Rationale: Synthetic web slings are sensitive to heat, chemicals, and UV
exposure, which can degrade strength.
4. Which factor is most important in selecting a rigging plan?
A. Cost of rigging equipment
B. Operator preference
C. Load weight, geometry, and center of gravity
D. Crane color
Rationale: Proper rigging plans consider load characteristics to prevent
accidents or instability.
5. What is the primary hazard when lifting near energized power lines?
A. Wind interference
B. Equipment malfunction
C. Electrocution
D. Load imbalance
Rationale: Contact with or proximity to energized power lines is a major
electrocution hazard in lifting operations.
6. When performing a load chart calculation, which of the following must be
known?
A. Crane operator’s experience
B. Radius, boom length, and load weight
C. Color of the crane
D. Ground surface type only
Rationale: Accurate load chart calculations require the load weight, boom
length, and radius to ensure safe lift.
7. What is the recommended sling angle limit for optimal load stability?
A. 15°
B. 30°
C. 45°
D. 60°
Rationale: Sling angles less than 45° can excessively increase sling tension,
reducing safety.
, 8. Which type of hitch is recommended for a load with an uneven center of
gravity?
A. Choker hitch
B. Vertical hitch
C. Bridle hitch
D. Basket hitch
Rationale: Bridle hitches allow multiple attachment points to balance
irregular or off-center loads.
9. What does SWL stand for in rigging equipment?
A. Safe Work Level
B. Safe Working Load
C. Standard Wire Limit
D. Sling Weight Limit
Rationale: SWL indicates the maximum load that can be safely lifted with
a piece of rigging equipment.
10.Which inspection criterion is critical for wire rope slings?
A. Length of rope only
B. Broken wires, kinks, corrosion, and wear
C. Color and coating
D. Manufacturer name
Rationale: Wire rope integrity is essential for safe lifting; damaged or
worn ropes must be removed from service.
11.What is the purpose of a spreader bar?
A. Reduce crane power requirements
B. Increase load weight capacity
C. Distribute load to prevent sling damage
D. Shorten lift time
Rationale: Spreader bars help distribute weight evenly, preventing
overloading and damage to slings or loads.
12.When performing a lift, who is responsible for the final determination of
the lift plan?
