INTRODUCTION
This comprehensive practice assessment is designed to prepare candidates for the NCCCO Rigger Level II
Certification Examination. The examination evaluates the knowledge and skills required to safely plan,
execute, and supervise complex rigging operations independently. Candidates are assessed on their
ability to estimate load weights, determine centers of gravity, select appropriate rigging components
based on capacity, perform pre-use inspections, and apply relevant ASME and OSHA standards. The
assessment includes both direct knowledge questions and scenario-based problems that emphasize real-
world application, critical thinking, and professional decision-making. Mastery of these domains
demonstrates competency in performing advanced rigging tasks safely and effectively.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary distinction between a Rigger Level I and a Rigger Level II certification?
,A. Level II riggers only perform lifts under direct supervision
B. Level II riggers are limited to basic hitch configurations
C. Level II riggers plan and execute complex lifts independently
D. Level II riggers are not required to calculate load weights
🟢 C. Level II riggers plan and execute complex lifts independently
🔴 Explanation: The NCCCO Rigger Level II certification qualifies individuals to select rigging
components and procedures based on rigging capacity and to perform rigging tasks unsupervised,
including complex lifts requiring calculations and professional judgment .
Question 2
When preparing a lift plan, which document provides the maximum safe lifting capacity at various
boom lengths and angles?
A. Rigging gear inspection log
B. Crane load chart
C. OSHA regulation manual
D. Sling manufacturer's catalog
🟢 B. Crane load chart
🔴 Explanation: The load chart is the authoritative document that specifies the crane's lifting capacity
under specific configurations of boom length, radius, and angle, ensuring the lift remains within safe
operational limits.
Question 3
A load weighing 12,000 lb is lifted using a two-leg bridle hitch with sling legs at a 45° angle from
horizontal. What is the approximate tension on each sling leg?
A. 6,000 lb
B. 8,485 lb
C. 4,243 lb
D. 10,392 lb
🟢 B. 8,485 lb
🔴 Explanation: Tension per leg = (Load Weight ÷ Number of Legs) ÷ sin(angle). At 45°: (12,000 ÷ 2) ÷
0.7071 = 6,000 ÷ 0.7071 = 8,485 lb.
Question 4
Which condition requires immediate removal of an alloy steel chain sling from service?
A. Minor surface discoloration
B. A stretched link or fitting
C. Light rust on the chain surface
D. A single broken wire on the outer surface
🟢 B. A stretched link or fitting
,🔴 Explanation: ASME B30.9 specifies that stretched chain links or fittings indicate overloading and are
a mandatory removal criterion with no allowable tolerance .
Question 5
What is the minimum recommended sling angle for a lifting operation to avoid excessive tension?
A. 15°
B. 20°
C. 30°
D. 45°
🟢 C. 30°
🔴 Explanation: Sling angles below 30° from horizontal cause disproportionately high tension in the
sling legs, increasing the risk of failure and reducing the effective capacity of the rigging assembly.
Question 6
Who is responsible for appointing the signalperson for a lifting operation?
A. The crane operator
B. The rigger
C. The lift director
D. The site safety officer
🟢 C. The lift director
🔴 Explanation: The lift director has overall responsibility for the lift and must ensure that a qualified
signalperson is designated and communicates effectively with the crane operator throughout the
operation.
Question 7
What does the term "working load limit" (WLL) represent for rigging hardware?
A. The weight of the hardware itself
B. The maximum load the hardware is designed to support under specified conditions
C. The load at which the hardware will break
D. The load that causes permanent deformation
🟢 B. The maximum load the hardware is designed to support under specified conditions
🔴 Explanation: WLL is the maximum mass or force that a component is authorized to support in a
particular service condition, accounting for the design factor and intended application.
Question 8
A wire rope sling has 6 broken wires in one strand in one rope lay. What action is required?
A. The sling may continue in service with reduced capacity
B. The sling must be removed from service
C. The sling can be used for light loads only
D. The sling must be re-inspected in 30 days
, 🟢 B. The sling must be removed from service
🔴 Explanation: ASME B30.9 establishes that 5 broken wires in one strand in one rope lay is the
removal threshold for strand-laid and single-part wire rope slings .
Question 9
When lifting a load with an off-center center of gravity, what is the primary risk?
A. Increased wind resistance
B. Uneven load distribution and possible tipping
C. Reduced crane hydraulic pressure
D. Slower lifting speed
🟢 B. Uneven load distribution and possible tipping
🔴 Explanation: An off-center center of gravity causes unequal tension in the sling legs and can result
in load rotation, shifting, or tipping during the lift, compromising stability and safety.
Question 10
What is the purpose of a tag line during a lifting operation?
A. To increase the lifting capacity of the crane
B. To control load rotation and movement
C. To reduce sling tension
D. To serve as a backup lifting line
🟢 B. To control load rotation and movement
🔴 Explanation: Tag lines allow riggers to guide and stabilize the load from a safe distance, preventing
uncontrolled rotation and ensuring the load is positioned accurately without personnel touching the
load.
Question 11
Which grade of chain is typically used for overhead lifting applications?
A. Grade 30
B. Grade 43
C. Grade 70
D. Grade 80 or 100
🟢 D. Grade 80 or 100
🔴 Explanation: Grade 80 and Grade 100 alloy steel chains are specifically designed for overhead
lifting, offering higher strength-to-weight ratios and traceability required for critical lifting operations.
Question 12
A synthetic web sling has a cut that exposes red warning yarns. What does this indicate?
A. The sling has exceeded its service life
B. The sling has sustained damage and must be removed from service
