Which factor influences a wheel loader’s stability when carrying a load?

• A. Engine horsepower
• B. Cabin color
• C. Load center of gravity, lift height, bucket position, ballast weight, ground slope, and tire condition
• D. Operator experience

Answer: (C)

Stability when carrying a load comes down to how the weight is distributed and how it shifts the tipping moment on the machine. The factors listed—load center of gravity, lift height, bucket position, ballast weight, ground slope, and tire condition—directly change that tipping moment and the base the loader sits on. Moving the load farther from the wheels or lifting it higher raises the center of gravity and makes tipping more likely; adjusting bucket position changes the load’s moment; adding ballast counteracts tipping forces; a slope adds a gravitational component that can push the machine to tip; and tire condition affects the contact patch and grip, influencing stability under load. Engine horsepower and operator experience influence performance, but they don’t change the fundamental stability margin, and cabin color has no effect.
