CLT CLT Material Handling & Equipment 2 — Questions and Answers
Question 1: What is the primary safety concern when operating a forklift with the load elevated while traveling?
- Fuel consumption increases significantly
- The center of gravity shifts upward, increasing the tip-over risk (Correct answer)
- The tires wear out faster
- Visibility of traffic signs is reduced
Correct answer: The center of gravity shifts upward, increasing the tip-over risk
Raising the forks with a load elevates the forklift's center of gravity, significantly increasing the risk of tipping over, especially when turning or traveling on uneven surfaces.
Question 2: Which conveyor system uses a slight incline to allow items to move without a motor?
- Belt conveyor
- Gravity roller conveyor (Correct answer)
- Chain conveyor
- Pneumatic conveyor
Correct answer: Gravity roller conveyor
Gravity roller conveyors use slightly inclined rollers that allow items to move downhill by gravity without any power source, making them energy-efficient.
Question 3: What is the purpose of wheel chocks when a truck is positioned at a loading dock?
- To guide the truck into the correct dock position
- To prevent the truck from rolling away during loading and unloading (Correct answer)
- To level the truck bed for easier loading
- To signal to other drivers that the dock is occupied
Correct answer: To prevent the truck from rolling away during loading and unloading
Wheel chocks are wedge-shaped blocks placed against truck tires to prevent the vehicle from rolling while being loaded or unloaded, preventing deadly 'trailer creep' accidents.
Question 4: What does the term 'load center' mean in forklift operations?
- The center of the warehouse where loads are staged
- The horizontal distance from the fork face to the load's center of gravity (Correct answer)
- The maximum number of loads a forklift can carry per shift
- The designated storage location for heaviest inventory items
Correct answer: The horizontal distance from the fork face to the load's center of gravity
The load center is the horizontal distance from the front face of the forks to the load's center of gravity, standardized at 24 inches for typical pallets.
Question 5: Which warehouse system uses computer-controlled equipment to automatically store and retrieve items in high-density configurations without traditional aisles?
- Selective racking
- Mobile shelving
- Drive-through racking
- Automated Storage and Retrieval System (AS/RS) (Correct answer)
Correct answer: Automated Storage and Retrieval System (AS/RS)
An Automated Storage and Retrieval System (AS/RS) uses robotic cranes or shuttles controlled by computers to store and retrieve inventory automatically, maximizing density and throughput.
Question 6: How frequently does OSHA require forklifts to be inspected?
- Weekly
- Monthly
- Before each shift (or daily if operated continuously) (Correct answer)
- Annually by a certified technician
Correct answer: Before each shift (or daily if operated continuously)
OSHA requires that forklifts be inspected before each shift, or at least daily if operated continuously across multiple shifts, to identify defects before they cause incidents.
