A forklift is rated at 6,000 lbs. The operator needs to lift a load using a 12-inch thick attachment. How does the attachment affect the rated capacity?
Answer: It reduces the effective capacity because the load center moves further from the forks
Any attachment adds weight and shifts the load center forward, requiring a derating of the nameplate capacity as shown on the attachment capacity plate.
Which of the following is a characteristic of an 'explosive atmosphere' that would require an explosion-proof forklift (EX designation)?
Answer: Locations where flammable vapors, gases, or combustible dust are present in air
EX-rated forklifts are designed to prevent electrical sparks or heat that could ignite flammable vapors, gases, or dust in hazardous classified locations.
What is the recommended method for determining if a load is within the forklift's safe capacity when the load weight is unknown?
Answer: Check the load's shipping documents, markings, or ask the supervisor
The safest method is to verify the load weight through shipping documents, weight markings on the load, or checking with a supervisor before attempting to lift.
What is 'dynamic load capacity' in the context of forklift operations?
Answer: The reduced capacity that accounts for the forces created by acceleration, deceleration, and turning
Dynamic forces from movement reduce effective load capacity; a load safe when stationary may cause tip-over when the forklift accelerates, brakes, or turns.
When handling a load with irregular shape or unusual weight distribution, what should the operator do before lifting?
Answer: Identify the load's center of gravity and position forks accordingly to balance the load
Locating the load's center of gravity and centering the forks beneath it ensures the load is balanced on the forks before lifting.
What is the primary purpose of 'stretch wrap' (stretch film) when applied to palletized loads?
Answer: To unitize and stabilize individual items on a pallet, preventing shifting during transport
Stretch wrap binds multiple items together as a single unit, preventing shifting, sliding, or falling during forklift handling and transport.
Which of these describes the proper procedure when a forklift must travel over a dock plate or bridge plate?
Answer: Cross straight and centered, ensuring the plate's capacity exceeds the combined weight of truck and load
The combined weight of the loaded forklift must not exceed the dock plate's rated capacity, and crossing straight prevents the plate from sliding or tipping.
