Question: Under what condition would an articulating wheel loader be most susceptible to lateral (side-to-side) instability due to a high centre of gravity?
Answer options:
- When travelling straight on level ground with an empty bucket. ✅ When turning sharply on an uneven or sloped surface with a raised, heavy load.
- When digging into a bank with the bucket near ground level.
- When performing routine maintenance with the parking brake engaged.
Correct answer: When turning sharply on an uneven or sloped surface with a raised, heavy load.
Explanation: Turning sharply on uneven terrain or a slope, especially with a raised, heavy load, dramatically shifts the machine's centre of gravity, increasing the risk of a side-tip. Articulation further contributes to the instability in such scenarios by allowing significant weight transfer.
