A fully loaded wheel loader is traversing a temporary access ramp constructed of compacted earth. The operator notices one side of the ramp feels softer than the other. What principle of stability is most critical to consider here, and what action should be taken?

Question: A fully loaded wheel loader is traversing a temporary access ramp constructed of compacted earth. The operator notices one side of the ramp feels softer than the other. What principle of stability is most critical to consider here, and what action should be taken?

Answer options:

• Kinetic energy; increase speed to get across quickly.
• Leverage; position the load to the higher side of the ramp. ✅ Ground pressure and centre of gravity; reduce speed and navigate the ramp cautiously to maintain an even weight distribution.
• Hydraulic balance; avoid using bucket functions while on the ramp.

Correct answer: Ground pressure and centre of gravity; reduce speed and navigate the ramp cautiously to maintain an even weight distribution.

Explanation: Soft ground on one side affects the machine's effective ground pressure and changes its support base, directly impacting the centre of gravity relative to the base. Reducing speed and careful navigation helps maintain an even weight distribution and reduces dynamic forces that could induce a tip-over.
