Question: An articulated wheel loader is turning sharply on uneven ground. What is the primary stability concern for the operator?
Answer options:
- Loss of hydraulic pressure to the steering cylinders. ✅ Roll-over due to the shift in the machine's centre of gravity.
- Excessive tire wear on the inner wheels of the turn.
- Damage to the articulation joint from torsional forces.
Correct answer: Roll-over due to the shift in the machine's centre of gravity.
Explanation: Articulated steering significantly shifts the machine's centre of gravity, especially during sharp turns, increasing the risk of a roll-over, particularly on uneven ground. OPSWA training emphasizes understanding this dynamic stability factor.
