Q&A| Instant Download Pdf
1. What is the minimum OSHA-required breaking strength ratio for a sling
used in crane rigging?
A. 3:1
B. 5:1
C. 7:1
D. 10:1
This ratio ensures that the sling’s breaking strength is sufficiently
greater than the maximum load, providing a substantial safety
margin in lifting applications.
2. Which of the following is the most critical factor when selecting rigging
hardware?
A. Color of hardware
B. Load capacity
C. Manufacturer’s country
D. Age of the operator
Rigging hardware must be selected based on load capacity to ensure
it can safely support the intended lift without failure.
,3. Before lifting, slings should be inspected for what primary defect?
A. Length markings
B. Color fading
C. Cuts, frays, or broken wires
D. Manufacturer’s logo
Visible damage such as cuts, frays, or broken wires can significantly
weaken a sling and lead to failure during a lift.
4. What is the primary purpose of a tag line?
A. To measure load weight
B. To control load rotation and movement
C. To secure the crane to ground
D. To tether the operator
Tag lines help control the load’s movement during lifts to prevent
uncontrolled swinging that could endanger workers or equipment.
5. A load chart must be consulted primarily to determine:
A. Operator certification requirements
B. Fuel type for equipment
C. Maximum allowable load at specific boom and radius
D. Paint specifications
Load charts provide essential data on the maximum load a crane can
handle under specific conditions, ensuring safe operations.
6. Which angle is most critical when calculating sling tension?
A. 15°
B. Sling leg angle to horizontal
C. Boom angle
D. Wind direction
The sling leg angle directly affects tension; smaller angles greatly
increase tension, which must be calculated to avoid overload.
, 7. OSHA requires that rigging fittings be of what minimum grade if they
are to be used for overhead lifting?
A. Grade 30
B. Grade 80
C. Grade 100
D. Grade 120
Grade 80 fittings meet OSHA standards for overhead lifting,
providing appropriate strength and reliability.
8. Which of the following should never be done with a synthetic sling?
A. Use with a softener
B. Inspect before use
C. Expose to sharp edges without protection
D. Use at appropriate angle
Sharp edges can cut or damage synthetic fibers; protective measures
like edge pads must always be used.
9. What device is used to prevent a load from inadvertently sliding off the
hook?
A. Shackle
B. Latch
C. Turnbuckle
D. Spreaders
A latch secures the load on the hook, reducing the chance of
accidental disengagement.
10. When rigging a load, which factor must be determined first?
A. Color of rigging gear
B. Length of rigging personnel’s names
C. Load weight
D. Crane operator experience
