Forklift certification Certification Workplace Forklift 3 — Questions and Answers
Question 1: What does the data plate (nameplate) on a forklift primarily tell the operator?
- The operator's certification date
- The rated load capacity and load center information (Correct answer)
- The last service date
- The fuel type only
Correct answer: The rated load capacity and load center information
The data plate lists the truck's rated capacity, load center, and other specifications the operator must follow.
Question 2: The standard load center used to rate most forklift capacities is measured at:
- 12 inches from the face of the forks
- 24 inches from the face of the forks (Correct answer)
- 36 inches from the mast
- The tip of the forks
Correct answer: 24 inches from the face of the forks
Most forklift capacities are rated at a 24-inch load center measured from the fork face.
Question 3: What happens to a forklift's stability if the load is placed farther out on the forks than the rated load center?
- Capacity increases
- Effective capacity decreases and tip-over risk rises (Correct answer)
- Nothing changes
- The truck becomes more stable
Correct answer: Effective capacity decreases and tip-over risk rises
A load beyond the rated center shifts the center of gravity forward, reducing capacity and increasing tip-over risk.
Question 4: The 'stability triangle' of a sit-down counterbalanced forklift is formed by:
- The two front tires and the load
- The two front wheels and the center of the rear axle (Correct answer)
- The mast and the two forks
- The seat and the two front wheels
Correct answer: The two front wheels and the center of the rear axle
The stability triangle connects the two front wheels and the pivot point at the center of the rear (steer) axle.
Question 5: To keep the forklift stable, the combined center of gravity must remain:
- Outside the stability triangle
- Within the stability triangle (Correct answer)
- Directly over the rear axle
- As high as possible
Correct answer: Within the stability triangle
The truck stays upright only while the combined center of gravity stays inside the stability triangle.
Question 6: Why is it dangerous to raise a load high while traveling?
- It uses more fuel
- It raises the center of gravity and greatly increases tip-over risk (Correct answer)
- It damages the mast chains
- It has no real effect
Correct answer: It raises the center of gravity and greatly increases tip-over risk
Raising the load lifts the center of gravity, making the truck much more likely to tip, especially when turning.
Question 7: What is a counterweight on a forklift designed to do?
- Add speed
- Balance the weight of the load on the forks (Correct answer)
- Protect the operator's head
- Cool the engine
Correct answer: Balance the weight of the load on the forks
The counterweight at the rear offsets the load on the forks to keep the truck balanced.
