What is the relationship between the load's center of gravity and stability?

• A. The higher the load center of gravity, the less stable the machine becomes
• B. The height of the load center has no effect
• C. A lower center increases tipping risk
• D. Stability is unaffected by load position

Answer: (A)

Stability comes from where the combined center of gravity of the loader and its load sits relative to the wheelbase. If the load center of gravity is high, the overall center of gravity rises and moves closer to the edge of the support polygon, making it easier for the machine to tip during lifts, turns, or on slopes. Lowering the load’s center of gravity keeps the gravity line lower and more centered within the wheelbase, increasing resistance to tipping. So raising the load reduces stability, while keeping the load lower improves stability.
