A telehandler is working on a paved surface with a 3% slope. The operator has the boom extended laterally to the side, but within the manufacturer's specified lateral reach. How does the slope affect the lateral stability of the telehandler?

Question: A telehandler is working on a paved surface with a 3% slope. The operator has the boom extended laterally to the side, but within the manufacturer's specified lateral reach. How does the slope affect the lateral stability of the telehandler?

Answer options: ✅ The slope reduces the effective base of the stability triangle on the downhill side, increasing the risk of lateral tipping.

• The slope increases the counterweight effect, improving lateral stability.
• The slope has no impact on lateral stability as long as the machine is level.
• The telehandler's suspension system compensates entirely for the slope, negating its effect.

Correct answer: The slope reduces the effective base of the stability triangle on the downhill side, increasing the risk of lateral tipping.

Explanation: Operating on a slope, even a slight one, shifts the telehandler's centre of gravity, reducing the effective stability base on the downhill side. This significantly increases the risk of lateral tipping, especially when the boom is extended laterally. Provincial OHS regulations emphasize the need for level surfaces or careful evaluation on slopes.
