ADVANCED RIGGER PRACTICE EXAM 2
QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) PLUS RATIONALES
2025
1. What is the purpose of a load chart?
A. To estimate equipment costs
B. To determine the capacity and configuration limits of the crane
C. To schedule lifting activities
D. To communicate with the lift director
Load charts are used to determine the crane's capabilities and
limitations for safe lifting operations.
2. Which of the following is most critical when selecting rigging for a lift?
A. Color of the sling
B. Manufacturer of the crane
C. Load weight and center of gravity
D. Length of the sling
, Understanding the load weight and center of gravity is essential for
safe and balanced lifting.
3. A basket hitch with two legs has what effect on load capacity?
A. Increases capacity compared to a single vertical hitch
B. Decreases capacity
C. Has no effect
D. Is not recommended for lifting
A basket hitch shares the load between two sling legs, effectively
increasing capacity.
4. The angle between sling legs and the horizontal must be:
A. As steep as possible
B. At least 45 degrees to avoid excessive tension
C. Always 90 degrees
D. Less than 30 degrees
Angles less than 45° increase tension significantly, which can
overload the sling.
5. Which device helps determine the exact center of gravity of an
irregular load?
A. Tension gauge
B. Load moment indicator
C. Spreader bar
D. Sling angle calculator
, A load moment indicator can help locate the center of gravity by
displaying unbalanced loads.
6. Which hitch is least secure for controlling rotation?
A. Choker hitch
B. Vertical hitch
C. Double basket
D. Bridle hitch
Choker hitches allow for some movement and slippage, which can
permit rotation.
7. What does D/d ratio refer to in rigging?
A. Diameter of hook to diameter of crane cable
B. Diameter of sling to diameter of load or shackle
C. Depth of drum to drum diameter
D. Design factor of device
D/d ratio affects sling strength; smaller ratios reduce sling capacity
due to bending stress.
8. Synthetic slings must be removed from service when:
A. They are over 10 years old
B. They show signs of cuts, abrasions, or UV damage
C. The tag is missing
D. All of the above
Any visible damage or missing identification requires immediate
removal of the sling from service.
, 9. Which factor has the greatest impact on dynamic loading during a lift?
A. Sudden starts or stops
B. Temperature
C. Load color
D. Rope color
Dynamic loading from abrupt motion can cause forces much greater
than static weight.
10. Which of the following is considered a below-the-hook lifting
device?
A. Wire rope
B. Hook block
C. Spreader beam
D. Chain sling
Spreader beams help distribute the load and reduce sling angles,
classifying them as lifting devices.
11. What is the maximum load angle factor for a sling used at 60
degrees?
A. 1.0
B. 1.4
C. 1.15
D. 2.0
Load angle factors vary with sling angle; 60 degrees gives a factor of
about 1.15.
