1. During a critical lift involving a 75-ton crawler crane, the total
suspended load consists of a 60,000 lb steel vessel, a 2,500 lb
spreader beam, 1,200 lb rigging hardware, and 800 lb lifting slings.
Which weight should be used when verifying crane and rigging
capacity?
A. 60,000 lb only
B. 62,500 lb
C. 64,500 lb
D. 60,800 lb
Answer: C. 64,500 lb
Rationale: The entire suspended load includes the object, lifting beam,
shackles, hooks, slings, and all rigging accessories. Every component
below the hook contributes to the crane load and must be included in
capacity calculations.
2. Which OSHA regulation primarily governs cranes, derricks, and
rigging activities in construction?
A. 29 CFR 1910 Subpart D
B. 29 CFR 1926 Subpart CC
1
,C. 29 CFR 1910 Subpart O
D. 29 CFR 1926 Subpart M
Answer: B. 29 CFR 1926 Subpart CC
Rationale: Subpart CC specifically addresses crane operations,
qualification requirements, rigging, inspections, lift planning, and safety
procedures during construction activities.
3. A synthetic round sling is tagged with a vertical capacity of 20,000
lb. When used in a basket hitch, what is the maximum theoretical
capacity if both legs share the load equally?
A. 20,000 lb
B. 30,000 lb
C. 40,000 lb
D. 10,000 lb
Answer: C. 40,000 lb
Rationale: A balanced basket hitch generally doubles the vertical
capacity because two sling parts support the load equally, assuming
proper loading and no angle reduction.
4. A two-leg sling forms an angle of 30° from the horizontal. What is
the primary effect on sling tension?
A. Sling tension decreases significantly.
B. Sling tension equals half the load.
C. Sling tension increases dramatically.
D. Sling tension remains unchanged.
2
,Answer: C. Sling tension increases dramatically.
Rationale: As sling angles become smaller from the horizontal, tension
rises rapidly. Low sling angles create dangerously high forces within
each sling leg.
5. Which hitch provides the greatest resistance against load slippage?
A. Vertical hitch
B. Basket hitch
C. Choker hitch
D. Endless hitch
Answer: C. Choker hitch
Rationale: A properly tightened choker hitch grips the load and
minimizes movement, although its rated capacity is typically reduced
compared to vertical or basket hitches.
6. Which inspection finding requires immediate removal of a wire
rope sling from service?
A. Slight dirt accumulation
B. Manufacturer identification missing
C. Minor discoloration
D. Light surface rust
Answer: B. Manufacturer identification missing
Rationale: Without a readable identification tag, the sling's rated
capacity cannot be verified, making it unacceptable for use.
3
, 7. The center of gravity of a load is important because it determines:
A. Hook speed
B. Crane fuel consumption
C. Load stability during lifting
D. Wire rope diameter
Answer: C. Load stability during lifting
Rationale: Rigging above the center of gravity keeps the load balanced
and prevents uncontrolled tilting or rotation.
8. Which shackle should never be side loaded?
A. Screw pin anchor shackle
B. Bolt-type anchor shackle
C. Chain shackle
D. Any standard shackle unless specifically designed for side loading
Answer: D. Any standard shackle unless specifically designed for
side loading
Rationale: Standard shackles are engineered for inline loading. Side
loading significantly reduces strength and increases failure risk.
9. A load is expected to rotate freely during lifting. Which rigging
accessory best helps prevent uncontrolled spinning?
A. Wire rope clip
B. Tagline
C. Chain binder
