1. During the relocation of a 24,000-pound industrial stamping press, a
rigger must determine whether a two-leg wire rope sling assembly
rated at 14,000 pounds per leg in a vertical configuration can safely
support the load. Assuming the load is evenly distributed and all other
conditions are acceptable, what is the most important factor that
could significantly reduce the sling assembly's effective lifting capacity?
A. The color of the sling tag
B. The sling angle from horizontal
,C. The manufacturer's logo placement
D. The ambient temperature of 70°F
B. The sling angle from horizontal
The sling angle has a major impact on tension within each sling leg. As
sling angles decrease, the force carried by each leg increases substantially,
potentially exceeding the sling's working load limit even when the load
weight appears acceptable.
2. Before beginning a machinery move involving a large CNC machining
center, what is the first action a qualified industrial machinery rigger
should perform?
A. Connect the slings to the load
B. Operate the crane at low speed
C. Conduct a pre-lift hazard assessment
D. Remove all machine guards
C. Conduct a pre-lift hazard assessment
A pre-lift hazard assessment identifies risks, verifies site conditions,
confirms equipment suitability, and establishes safe procedures before any
lifting operation begins.
3. When determining the center of gravity of an irregularly shaped
industrial machine, why is locating the center of gravity critical?
,A. It determines paint requirements
B. It affects the load's balance during lifting
C. It establishes electrical grounding requirements
D. It determines operator certification levels
B. It affects the load's balance during lifting
The center of gravity determines how a load behaves when suspended.
Failure to identify it correctly can cause load shifting, tilting, or loss of
control during lifting operations.
4. Which hitch configuration generally provides the greatest load control
when lifting a long industrial machine that may shift during
movement?
A. Choker hitch
B. Vertical hitch
C. Basket hitch
D. Double-wrap choker hitch
D. Double-wrap choker hitch
A double-wrap choker hitch increases grip on the load and helps reduce
slippage, making it useful for machinery that may shift during handling.
5. A rigger discovers several broken wires in a wire rope sling during
inspection. What should be done?
, A. Continue using the sling until the project ends
B. Reduce the load weight by 10%
C. Remove the sling from service according to inspection criteria
D. Wrap tape around the damaged area
C. Remove the sling from service according to inspection criteria
Broken wires indicate deterioration and reduced strength. Damaged slings
must be removed from service when inspection criteria are exceeded.
6. What is the primary purpose of a tag line during a machinery lift?
A. Increase crane capacity
B. Control load rotation and movement
C. Reduce sling tension
D. Measure load weight
B. Control load rotation and movement
Tag lines allow personnel to control load swing and rotation while
maintaining a safe distance from suspended loads.
7. Which communication method takes precedence when standard hand
signals cannot be clearly seen by the crane operator?
A. Text messaging
B. Radio communication using established procedures
C. Verbal shouting without confirmation
D. Personal judgment by the operator
