Question: An articulated wheel loader is carrying a maximum rated load. What is the effect of steering the machine significantly while moving on an uneven, slippery surface?

Answer options: ✅ The machine's centre of gravity moves laterally, potentially exceeding the stability limits.

• The steering angle is reduced compared to an unloaded state.
• Traction is increased at the rear wheels due to weight transfer.
• The machine's overall length temporarily shortens, improving agility.

Correct answer: The machine's centre of gravity moves laterally, potentially exceeding the stability limits.

Explanation: When an articulated wheel loader steers, the front and rear frames pivot relative to each other, causing the machine's centre of gravity to shift laterally. This effect is exaggerated with a full load and on slippery or uneven surfaces, significantly reducing stability and increasing the risk of a side rollover if the stability limits are exceeded. Experienced operators must be acutely aware of their steering input in such conditions.
