Which action can cause tipping sideways related to turning with the load?

• A. Mast tilted forward
• B. Forward down a slope
• C. Side shift not centred
• D. Turning with load too high

Answer: (D)

Turning with a load that’s too high shifts the overall center of gravity upward and outward as you rotate. The forklift’s stability depends on the combined center of gravity staying inside the stability base formed by the wheels and axle points. When the load is raised, that CG sits higher and farther from the ground, so during a turn the centrifugal effect pushes the weight toward the outside of the curve. That creates a tipping moment to the side and can cause the forklift to topple sideways.

Lowering the load before or during turns keeps the CG closer to the ground and within the stability area, significantly reducing the sideways tipping risk. The other actions shift or tilt the load or affect balance in different ways (forward tipping or general instability) but the primary cause of tipping sideways during turning with a load is having the load too high.
