1. What is the primary responsibility of a rigger?
A. Operating the crane
B. Supervising the job site
C. Inspecting electrical systems
D. Attaching loads to lifting equipment safely
Correct because the rigger’s main duty is to select and attach rigging to
ensure safe lifting.
2. Which document provides the rated capacity of a sling?
A. OSHA regulations
B. Job safety analysis
C. Manufacturer’s tag or label
D. Lift plan
Manufacturer tags list working load limits and sling details.
3. What does WLL stand for?
A. Working Load Level
B. Working Load Limit
C. Weight Load Limit
D. Wire Load Length
WLL is the maximum load a rigging component can safely handle.
4. When is a lift considered a critical lift?
A. When lifting any load over 500 lb
B. When lifting during rain
, C. When the load exceeds a set percentage of crane capacity or involves
special risk
D. When lifting at night
Critical lifts involve higher risk and require special planning.
5. Which hitch provides the least amount of load security?
A. Basket hitch
B. Choker hitch
C. Vertical hitch
D. Double choker hitch
A vertical hitch offers no resistance to load movement.
6. What happens to sling capacity when used in a choker hitch?
A. Increases
B. Remains the same
C. Decreases
D. Doubles
Choker hitches reduce sling capacity due to angle and constriction.
7. What is the minimum design factor for wire rope slings?
A. 3:1
B. 4:1
C. 5:1
D. 10:1
Wire rope slings require a 5:1 design factor.
8. Which sling is best for sharp edges?
A. Synthetic web sling
B. Wire rope sling with edge protection
C. Round sling
D. Chain sling without protection
Wire rope with protection resists cutting better than synthetic slings.
9. What should be done if a sling tag is missing?
A. Estimate capacity
B. Use with lighter loads
C. Remove from service
, D. Ask the crane operator
Without identification, capacity cannot be verified.
10.What does a choker hitch do to the load?
A. Supports evenly
B. Tightens around the load
C. Lifts from two points
D. Prevents rotation
Choker hitches constrict around the load.
11.What is the purpose of a tagline?
A. Increase capacity
B. Control load rotation and movement
C. Protect slings
D. Secure the crane
Taglines help guide and stabilize loads.
12.What type of sling is most flexible?
A. Wire rope
B. Chain
C. Synthetic web or round sling
D. Fiber rope
Synthetic slings conform easily to load shapes.
13.What must be considered when calculating sling angles?
A. Load color
B. Crane height
C. Angle between sling and horizontal
D. Wind speed only
Sling tension increases as angles decrease.
14.What happens to tension when sling angles decrease?
A. Decreases
B. Remains constant
C. Increases
D. Becomes zero
Lower angles create higher forces in the slings.
