Question: You are backfilling a trench on a slight side slope with an articulated wheel loader. Which action significantly increases the risk of side-to-side instability while turning?
Answer options:
- Maintaining a constant engine RPM while turning.
- Turning uphill with an empty bucket. ✅ Articulating the machine beyond 50% of its maximum angle while travelling across the slope.
- Using the brake pedal to slow down before turning.
Correct answer: Articulating the machine beyond 50% of its maximum angle while travelling across the slope.
Explanation: Articulating an articulated loader, especially while traveling across a slope, shifts the machine's centre of gravity outwards, drastically increasing the risk of side-to-side overturning. Combining articulation with a side slope significantly compromises stability.
