INTRODUCTION
This practice assessment is designed to evaluate the proficiency of individuals seeking Level 2 Rigger
certification. The exam focuses on the complex knowledge required to select, inspect, and utilize rigging
equipment in multifaceted lifting environments. Candidates are assessed on their ability to perform load weight
calculations, determine center of gravity, and account for environmental factors and sling angles. The structure
consists of multiple-choice and scenario-based questions that mirror real-world rigging challenges. Emphasis is
placed on safety protocols, regulatory adherence, and critical decision-making skills necessary to ensure the
integrity of the lift and the safety of all personnel involved in crane and rigging operations.
SECTION ONE: QUESTIONS 1–100
1. When calculating the tension on a two-leg bridle hitch, what effect does a lower horizontal sling angle have
on the tension of each leg?
,A. Tension decreases
B. Tension remains constant
🟢 C. Tension increases
D. Tension is only affected by load weight
🔴 RATIONALE: As the horizontal sling angle decreases (becomes shallower), the multiplier for tension increases
significantly due to the increased horizontal force components.
2. According to ASME B30.9, how often must a periodic inspection of slings be performed by a designated
person?
A. Every shift
B. Monthly
🟢 C. At least annually
D. Every two years
🔴 RATIONALE: ASME B30.9 requires a documented periodic inspection at least annually, though more frequent
inspections may be required based on service conditions.
3. Which of the following is the most accurate method for determining the weight of a complex, fabricated
steel structure?
A. Estimating based on visual size
B. Using a bathroom scale
🟢 C. Consulting the manufacturer's prints or shipping documents
D. Calculating volume and multiplying by the density of water
🔴 RATIONALE: Engineering drawings and manufacturer specifications provide the most reliable weight data for
complex loads to ensure rigging capacity is not exceeded.
, 4. When using a sliding choker hitch on a bundle of pipes, the angle of choke should be greater than how
many degrees to maintain full capacity?
🟢 A. 120 degrees
B. 90 degrees
C. 60 degrees
D. 45 degrees
🔴 RATIONALE: A choke angle of less than 120 degrees reduces the rated capacity of the sling significantly; 120
degrees or more is required for 100% of the rated choker capacity.
5. A rigger is using a spreader beam to lift a long, flexible load. What is the primary purpose of the spreader
beam in this scenario?
A. To increase the crane's lifting capacity
🟢 B. To protect the load from crushing forces caused by sling angles
C. To allow for a single-point lift
D. To eliminate the need for a center of gravity calculation
🔴 RATIONALE: Spreader beams convert lifting forces into pure compressive forces on the beam, protecting the
load from the inward "pinch" or crushing forces of a standard bridle hitch.
6. If a load is non-symmetrical, where will the center of gravity always be located?
A. Directly in the geometric center
🟢 B. Directly below the hook point when the load is level
C. Toward the lighter end of the load
D. At the highest point of the load
, 🔴 RATIONALE: For a load to be stable and level, the center of gravity must be positioned directly below the hook
point.
7. Which hardware item is specifically designed to adjust the length of a sling leg to level a load?
A. Master link
B. Wire rope clip
🟢 C. Turnbuckle
D. Shackle
🔴 RATIONALE: Turnbuckles are used in rigging systems to provide small, precise adjustments to sling length for
leveling or tensioning purposes.
8. When using multi-leg slings, what is the maximum number of legs that are generally assumed to carry the
load if the load is rigid?
🟢 A. 2
B. 3
C. 4
D. 1
🔴 RATIONALE: In a rigid load, it is statistically likely that only two legs will bear the majority of the weight while
the others provide balance, unless the system is specifically adjusted.
9. What is the safety factor typically used for general purpose wire rope slings?
A. 3:1
B. 4:1
