1. When performing a load lift, what is the minimum number of
points a Level II Rigger must check on a crane before lift
execution?
A. 3
B. 5
C. 2
D. 4
Rationale: A Level II Rigger is required to verify at least five critical
points, including rigging hardware, load stability, crane capacity,
environmental conditions, and proper communication signals to
ensure a safe lift.
2. Which of the following types of hitches increases the risk of sling
instability if the load shifts during a lift?
A. Choker hitch
, B. Vertical hitch
C. Basket hitch
D. Bridle hitch
Rationale: A basket hitch can cause instability if the load is not
balanced properly. The weight is distributed across two points, which
can allow tilting or slipping if not carefully rigged.
3. The SWL (Safe Working Load) of a synthetic sling is based on which
of the following?
A. Rated capacity provided by the manufacturer
B. Observed lift testing
C. Load chart from the crane operator
D. Weight of the load plus 50%
Rationale: The Safe Working Load of a sling is determined by the
manufacturer through testing. Using the SWL ensures that the sling is
not overloaded beyond its rated capacity.
4. Which signal should be used when a lift must be stopped
immediately due to a hazard?
A. Raise hand slowly
B. Two short blasts of the whistle
C. Stop signal (arm raised vertically, hand open)
D. Circular motion with the hand
,Rationale: The stop signal is universally recognized and ensures
immediate halting of crane operation to prevent accidents.
5. When inspecting a chain sling, which of the following defects is
cause for immediate removal from service?
A. Light surface rust
B. Twist, gouge, or bent links
C. Slight elongation under load
D. Minor corrosion
Rationale: Any twist, gouge, or bend in a chain link compromises its
structural integrity and is grounds for removing the sling from service
immediately.
6. Which factor is critical when determining the number of slings
required for a multi-leg lift?
A. Color of the sling
B. Load weight distribution and center of gravity
C. Sling manufacturer preference
D. Number of riggers present
Rationale: Multi-leg lifts require proper weight distribution to prevent
overloading any single sling. Assessing the center of gravity is
essential to balance the load safely.
, 7. What is the primary reason for using a spreader bar in a lift?
A. Reduce the need for taglines
B. Prevent damage to the load and maintain load stability
C. Increase lifting speed
D. Reduce crane operator oversight
Rationale: A spreader bar distributes the lifting points and reduces the
potential for bending or crushing a load, ensuring stability and safety.
8. When using a synthetic web sling, which of the following should
be avoided?
A. Placing padding between the sling and load
B. Exposing the sling to sharp edges without protection
C. Using sling at proper angle
D. Inspecting sling prior to use
Rationale: Sharp edges can cut or abrade synthetic webbing, which
may result in sling failure. Proper protection must always be used.
9. The maximum allowable sling angle from the horizontal in a multi-
leg lift is typically:
A. 15°
B. 25°
C. 30°
D. 45°
