An operator is travelling down a 10% grade (10 metres drop over 100 metres horizontal distance) with a loaded wheel loader. To maintain optimal stability and control, what is the safest practice regarding machine orientation?

Question: An operator is travelling down a 10% grade (10 metres drop over 100 metres horizontal distance) with a loaded wheel loader. To maintain optimal stability and control, what is the safest practice regarding machine orientation?

Answer options:

• Always descend directly forward, using the bucket to push into the slope for braking if necessary. ✅ Descend in reverse with the bucket low, approximately 30 cm (12 inches) above the ground, facing uphill.
• Angle the machine slightly across the slope to increase traction.
• Maintain a reasonable speed and rely solely on the service brakes for control.

Correct answer: Descend in reverse with the bucket low, approximately 30 cm (12 inches) above the ground, facing uphill.

Explanation: When descending a slope, especially with a load, OPSWA and OHS regulations recommend travelling in reverse with the bucket low and facing uphill. This reorients the centre of gravity towards the uphill side, increasing stability and providing an 'emergency anchor' should control be lost. Travelling forward down a slope reduces braking effectiveness and increases the risk of tipping.
