When handling large flammable solid materials, a diesel engine power stacker is generally the best option due to its ability to operate safely in environments where flammable gases or vapors might be present. Diesel engines produce less risk of sparks compared to electric or hydraulic power sources, which can create potential ignition sources. Furthermore, diesel engines are more resilient in outdoor conditions and are typically designed to handle heavier loads, which is advantageous when moving large solid materials.

Electric power stackers, while effective in many environments, can pose risks in flammable areas if there is a battery event or short-circuit. Hydraulic power engines might not provide sufficient power for heavier loads that could be expected with the handling of large materials. Pneumatic engines are less common for stackers and typically not used for heavy-duty applications involving flammable materials. Therefore, diesel engines provide a practical balance of power, safety, and reliability in these specific operational contexts.
