RIGGER LEVEL I PRACTICE EXAM 1
QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) PLUS RATIONALES
2025
1. What is the primary purpose of a tag line during a lift?
A) To increase the load capacity
B) To control the load and prevent rotation or swinging
C) To attach the load to the hook
D) To signal the crane operator
Rationale: A tag line helps control the load's movement to prevent hazards such
as swinging.
2. When inspecting wire rope, which of the following is a cause for rejection?
A) Minor surface rust
B) Broken wires or kinks
C) Slightly flattened wires
D) Dirt on the surface
,Rationale: Broken wires or kinks weaken the rope and create safety hazards.
3. What does the Working Load Limit (WLL) represent?
A) The maximum weight the equipment can handle before breaking
B) The maximum load that should be applied under normal service conditions
C) The weight of the lifting equipment
D) The weight of the sling plus the load
Rationale: WLL is the maximum safe load the equipment is designed to handle
under normal use.
4. Which hitch provides the greatest lifting capacity?
A) Choker hitch
B) Basket hitch
C) Basket hitch with two legs
D) Vertical hitch
Rationale: A basket hitch with two legs shares the load, increasing capacity.
5. What should be the first step before performing a lift?
A) Attach the sling to the load
B) Position the crane boom
C) Conduct a job site hazard assessment
D) Signal the crane operator
, Rationale: Identifying hazards is crucial to ensure safety before starting the lift.
6. When should rigging equipment be removed from service?
A) After five years of use
B) When the load exceeds 80% of WLL
C) When damaged or defective
D) When a new rigging job starts
Rationale: Damaged or defective rigging is unsafe and must be removed
immediately.
7. Which of the following is NOT a type of sling commonly used in rigging?
A) Wire rope sling
B) Chain sling
C) Nylon harness
D) Synthetic web sling
Rationale: Nylon harnesses are for personal fall protection, not for lifting loads.
8. What is the minimum angle allowed between sling legs to ensure safe lifting?
A) 10 degrees
B) 30 degrees
C) 60 degrees
D) 90 degrees
