NSC Load Handling & Stability 2 — Questions and Answers
Question 1: When transporting a load on an incline, where should the load be positioned relative to the slope?
- Load facing downhill to improve visibility
- Load facing uphill on both ascent and descent (Correct answer)
- Load facing uphill only when going up, downhill when descending
- Load position does not matter on inclines
Correct answer: Load facing uphill on both ascent and descent
The load must always face uphill when traveling on a ramp to prevent it from sliding off the forks.
Question 2: What effect does raising the forks higher than necessary during travel have on forklift stability?
- It has no effect on stability
- It lowers the center of gravity and improves stability
- It raises the center of gravity and reduces stability (Correct answer)
- It only affects stability when the load is over 2,000 lbs
Correct answer: It raises the center of gravity and reduces stability
Raising forks elevates the combined center of gravity of the truck and load, narrowing the stability triangle margin and increasing tip-over risk.
Question 3: A forklift is rated at 5,000 lbs at a 24-inch load center. If the actual load center is 36 inches, the safe capacity is:
- Still 5,000 lbs because the load hasn't changed weight
- Reduced to approximately 3,333 lbs (Correct answer)
- Increased because a larger load center spreads weight better
- Reduced to 2,500 lbs automatically
Correct answer: Reduced to approximately 3,333 lbs
Capacity decreases proportionally as load center increases; 5,000 × (24/36) ≈ 3,333 lbs is the derated capacity.
Question 4: Which condition most increases the risk of a load shifting sideways during travel?
- Traveling at low speed on a flat surface
- Carrying an uneven or off-center load on the forks (Correct answer)
- Using both forks evenly spaced
- Keeping the mast tilted back slightly
Correct answer: Carrying an uneven or off-center load on the forks
An off-center load creates unequal weight distribution across the forks, making lateral shifting and tip-over more likely.
Question 5: What is the primary purpose of tilting the mast rearward when carrying a load?
- To increase travel speed safely
- To stabilize the load against the backrest and lower tip risk (Correct answer)
- To allow the operator to see over the load more easily
- To reduce wear on the front tires
Correct answer: To stabilize the load against the backrest and lower tip risk
Rear mast tilt cradles the load against the backrest extension, improving front-to-rear stability and preventing forward load slide.
Question 6: When stacking loads in racking, a forklift operator should ensure:
- The load is placed as quickly as possible to minimize mast extension time
- The load is fully supported by the rack beams before the forks are lowered (Correct answer)
- The forks are lowered before the load reaches the rack beams
- Rack capacity need not be considered if the forklift is within its rated capacity
Correct answer: The load is fully supported by the rack beams before the forks are lowered
The load must rest completely on the rack beams before the forks are withdrawn to avoid dropping or tipping the load.
Question 7: Which of the following describes the 'stability triangle' concept for counterbalanced forklifts?
- The triangular shape of the load as viewed from above
- The three-point suspension formed by the two front wheels and the rear axle pivot point (Correct answer)
- The angle of the mast at which loads become unstable
- The three-zone inspection area around the forklift
Correct answer: The three-point suspension formed by the two front wheels and the rear axle pivot point
The stability triangle is the area defined by the two front drive wheels and the center of the rear axle; the combined center of gravity must stay within this triangle.
