When procuring a Howo Fire Truck, you must prioritize the chassis model (e.g., Howo 7 or Howo T7H) and the engine horsepower (typically 290HP to 400HP) to ensure the vehicle can handle the weight of a full water tank. Key components include the fire pump flow rate (usually 30-60L/s), the monitor range (≥50m for water), and the tank material, where stainless steel or anti-corrosion treated carbon steel is preferred for longevity. Additionally, verify the PTO (Power Take-Off) reliability, as it is critical for driving the water pump during stationary operations.
