1. What is the primary purpose of a tag line?
A. To measure load weight
B. To control the load and prevent rotation
C. To inspect the crane hook
D. To lift personnel
Rationale: Tag lines are used to control and guide loads during lifting
to prevent uncontrolled movement or rotation.
2. When inspecting a wire rope before use, you should check for:
A. Color fading
B. Broken wires, kinks, corrosion, and wear
C. Length only
D. Lubricant type
Rationale: Wire ropes must be inspected for damage such as broken
wires, kinks, corrosion, and excessive wear to ensure safe operation.
3. The Working Load Limit (WLL) of a sling refers to:
A. The maximum weight the sling can lift ever
B. The maximum load the sling can safely lift under normal
, conditions
C. The weight of the sling itself
D. The breaking strength of the sling
Rationale: WLL is the safe load that a sling or lifting device can handle
during normal operations, usually a fraction of the breaking strength.
4. What is the first step in a lift planning process?
A. Attach the sling
B. Conduct a site and load assessment
C. Signal the crane operator
D. Move the load
Rationale: Lift planning begins with evaluating the site, load
characteristics, and potential hazards to ensure safety.
5. Which of the following is NOT an acceptable hitch for slings?
A. Vertical hitch
B. Basket hitch
C. Choker hitch
D. Tied knot hitch
Rationale: Tying knots in slings significantly reduces strength and is
unsafe; vertical, basket, and choker hitches are standard.
6. The minimum distance from energized power lines that must be
maintained when working with cranes is:
A. 5 feet
B. 10 feet
C. 20 feet
D. 50 feet
Rationale: OSHA and NCCCO standards require maintaining at least 20
feet from power lines to prevent electrical hazards.
, 7. When performing a pre-lift inspection, which component of the
rigging should be checked?
A. Crane counterweights
B. Slings, hooks, shackles, and lifting devices
C. Operator logbooks
D. All ground personnel
Rationale: Pre-lift inspections focus on rigging hardware to detect
wear, deformation, or damage.
8. What does a choke hitch do to a sling?
A. Doubles the WLL
B. Reduces the WLL by approximately 20%
C. Has no effect on WLL
D. Makes lifting faster
Rationale: A choke hitch reduces the effective working load of a sling
due to the bending stress applied.
9. What is the most common cause of rigging accidents?
A. Weather
B. Improper rigging practices
C. Operator fatigue
D. Equipment age
Rationale: Rigging accidents are most often caused by improper sling
selection, attachment, or load control.
10. When rigging a load for a vertical lift, where should the hook
be positioned?
A. Off-center to reduce swing
B. Directly over the center of gravity
C. At any convenient angle
D. Above personnel
