National Commission for the Certification of Crane Operators (NCCCO) Rigger Level I Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the main responsibility of a Level I Rigger?

a) Supervising crane operations

b) Conducting load testing

c) Inspecting and preparing rigging before a lift

d) Operating the crane

Rationale: A Level I Rigger’s primary role is to inspect and prepare

rigging equipment before and during lifting operations under the supervision of a qualified person.

• When should rigging equipment be inspected?

a) Every month 1 / 4

b) Only after heavy use

c) Before each use

d) Once a year

Rationale: Rigging equipment must be visually inspected before each

use to ensure safety and functionality.

• What is the minimum design factor for wire rope used in lifting

applications?

a) 3:1

b) 4:1

c) 5:1

d) 6:1

Rationale: Wire rope used for lifting must have a design factor of at

least 5:1 according to OSHA and ASME standards.

• What type of hitch is best for lifting cylindrical loads?

a) Vertical hitch

b) Choker hitch

c) Basket hitch

d) Double hitch

Rationale: A choker hitch provides a snug grip on round or cylindrical

objects, preventing slipping.

• What is the main purpose of a tag line?

a) To lift the load higher

b) To control load movement and rotation 2 / 4

c) To secure rigging to the crane hook

d) To measure load weight

Rationale: Tag lines are used to control the load and prevent

unwanted rotation or swinging during lifting.

• Which type of sling is best for minimizing load damage?

a) Synthetic web sling

b) Wire rope sling

c) Chain sling

d) Alloy sling

Rationale: Synthetic web slings are soft and flexible, reducing the

chance of load surface damage.

• What must be known before a lift begins?

a) Wind direction

b) Load weight and center of gravity

c) Crane manufacturer

d) Sling color code

Rationale: Knowing the load’s weight and center of gravity ensures

proper sling selection and balanced lifting.

8. The identification tag on a synthetic sling must include:

a) Length and color

b) Manufacturer, rated capacity, and type

c) Inspection date only

d) Owner’s name 3 / 4

Rationale: Each sling must have a tag showing the manufacturer,

rated capacity, and type to ensure traceability.

• What happens if the sling angle decreases?

a) The load capacity increases

b) The load capacity decreases

c) The load capacity remains the same

d) The sling length increases

Rationale: As the sling angle decreases, the tension in the sling

increases, reducing its effective load capacity.

10. A sling angle of 30° increases tension by approximately:

• 10%
• 25%
• 100%
• 200%

Rationale: A 30° sling angle doubles the tension on each leg

compared to a vertical lift.

• Which hitch provides the best load stability?

a) Choker hitch

b) Basket hitch (double leg)

c) Single vertical hitch

d) Running hitch

Rationale: A double basket hitch distributes the load evenly and

offers superior stability.
