NSC Load Handling & Stability 3 — Questions and Answers
Question 1: A forklift operator is asked to pick up two separate pallets stacked on top of each other. What must be verified first?
- That the travel path is clear
- That the combined load weight does not exceed the forklift's rated capacity (Correct answer)
- That the top pallet is lighter than the bottom pallet
- That the forks are extended to maximum width
Correct answer: That the combined load weight does not exceed the forklift's rated capacity
The total combined weight of both pallets must be checked against the nameplate capacity before the lift is attempted.
Question 2: When handling a long load (e.g., lumber or pipe) that extends well beyond the fork tips, the operator should:
- Travel at normal speed since fork length is not a capacity factor
- Use a load extension attachment rated for the actual load center distance (Correct answer)
- Add counterweight to the rear of the forklift
- Carry the load with forks fully raised for visibility
Correct answer: Use a load extension attachment rated for the actual load center distance
Extended loads shift the load center farther from the front axle, requiring a rated attachment and adjusted capacity to maintain safe operation.
Question 3: What is the safest action if a load begins to shift or tip while the forks are elevated?
- Quickly lower the load and do not attempt to correct by moving the truck (Correct answer)
- Accelerate to stabilize the load through momentum
- Jump from the forklift immediately
- Try to catch the load with the mast tilt control
Correct answer: Quickly lower the load and do not attempt to correct by moving the truck
Lowering the load immediately reduces the center of gravity and minimizes tip-over risk; sudden truck movement can worsen the situation.
Question 4: Which factor does NOT directly reduce a forklift's load capacity?
- An attachment that adds weight to the carriage
- A load center farther than the rated distance
- The color of the load being lifted (Correct answer)
- Elevated fork height when rated capacity is specified at ground level
Correct answer: The color of the load being lifted
Load color has no bearing on forklift capacity; attachments, load center distance, and fork height are all real capacity-reducing factors.
Question 5: When picking up a load from a floor stack, the operator should position the forks so that:
- Only one fork contacts the pallet for quicker entry
- Both forks are fully and evenly inserted under the load to the load face (Correct answer)
- The forks are inserted halfway for easier removal
- The fork tips extend well past the opposite side of the pallet
Correct answer: Both forks are fully and evenly inserted under the load to the load face
Full, even fork insertion distributes the load correctly and prevents the pallet from tipping or catching on the fork tips.
Question 6: What immediate hazard is created when a heavily loaded forklift turns too sharply at speed?
- Excessive tire wear on the rear wheels
- Lateral tip-over due to centrifugal force shifting the center of gravity outside the stability triangle (Correct answer)
- Hydraulic fluid overheating
- Reduced battery voltage on electric forklifts
Correct answer: Lateral tip-over due to centrifugal force shifting the center of gravity outside the stability triangle
Sharp turns at speed produce centrifugal force that can push the combined center of gravity beyond the stability triangle, causing a lateral tip-over.
Question 7: Pallets should be inspected before loading because:
- Damaged pallets may fail and cause the load to drop, injuring personnel or damaging goods (Correct answer)
- New pallets increase the load center distance
- Pallet weight must be added to capacity calculations in all cases
- Painted pallets can reduce fork friction and cause slippage
Correct answer: Damaged pallets may fail and cause the load to drop, injuring personnel or damaging goods
Broken boards, missing blocks, or damaged stringers can cause pallet collapse under load, creating a sudden drop and potential injury.
