Which of the following increases the overall stability of a Mobile Elevating Work Platform?

The correct answer enhances the overall stability of a Mobile Elevating Work Platform (MEWP) by ensuring that the center of gravity is properly positioned. A correct center of gravity helps distribute the weight evenly throughout the platform, minimizing the risk of tipping or instability during operation. When the center of gravity is low and well-aligned, it enhances the platform's balance and control, allowing it to operate safely at various heights and conditions.

In contrast, additional operators do not inherently increase stability and may complicate the operation. Heavier materials can affect stability negatively by raising the center of gravity if not properly managed. Taller extensions may also lead to a higher center of gravity, which can decrease stability and increase the risk of tipping, especially in windy or uneven ground conditions. Hence, maintaining the correct center of gravity is crucial for ensuring safe and stable operation of MEWPs.
