1. Product Overview

This heavy-duty fire truck adopts the SINOTRUK HOWO TX 6×4 rear double axle left-hand drive chassis, fully compliant with Euro VI emission standards for overseas market registration. It is equipped with a 540HP high-torque diesel engine, delivering strong climbing power and stable cross-country perform

ance for emergency missions.

2. Working Principle of the Foam Fire System

1. Power transmission: The power take-off transfers engine power to drive the fire pump, continuously drawing water from external water sources or the onboard water tank.

2. Proportion mixing: High-speed water flow creates negative pressure inside the Venturi tube, automatically sucking foam concentrate into the pipeline. The mixing ratio is precisely controlled at 3%–6% without manual adjustment.

3. Foam generation: The mixed liquid passes through the foaming net and mixes with air to form dense, stable fire suppression foam.

4. Fire suppression: The foam is sprayed onto burning liquid surfaces to form an airtight covering layer, cutting off oxygen while absorbing heat to cool down combustibles, which effectively stops fire and prevents re-ignition.

   The system can quickly switch between pure water mode and foam mode to handle both Class A solid fires and Class B flammable liquid fires flexibly.

3. Real Application Scenarios in Daily Operations

1. Petrochemical plants, oil depots and fuel tank farms: Put out diesel, gasoline and crude oil tank fires, control large-area liquid leakage combustion.

2. International seaports and oil terminals: Fight ship fuel fires and dangerous goods container blazes near docks.

3. Airports: Handle aircraft aviation fuel fires on runways and parking aprons.

4. Chemical warehouses and pharmaceutical factories: Suppress alcohol, solvent and hydrocarbon chemical fires.

5. Municipal fire brigades: Respond to large warehouse, logistics park and heavy vehicle fuel fires in urban areas.

   With 15 cubic meters of liquid storage, this truck can sustain long-time continuous operation without frequent refilling, perfectly matching long-duration industrial fire fighting tasks.

5. Buying Guide: How to Select a Qualified Heavy Foam Fire Truck

1. Confirm chassis configuration: Choose 6×4 rear double axle, left-hand drive and Euro VI emission for overseas customs clearance. 540HP engine is essential for fully loaded 15-ton liquid cargo on rugged roads.

2. Check tank quality: Require carbon steel water tank + 304 stainless steel foam tank with anti-wave plates and pressure leakage test reports to avoid cracking and leakage.

3. Verify hydraulic & fire equipment: Select automatic Venturi proportioner and CB series high-flow fire pump; the fire monitor should have a jet range above 65 meters.

4. Match local fire standards: Select AFFF alcohol-resistant foam pipeline system if you need to handle polar solvent chemical fires.

5. Pick manufacturers with export qualification: Ensure complete vehicle certification, chassis certification and CIQ inspection documents for smooth port clearance.

   Avoid low-cost simplified versions without anti-corrosion treatment and manual mixing devices, which will cause frequent breakdowns in high-intensity fire missions.

6. Practical Operation & Maintenance Tips

Daily Operation

• Warm up the engine before starting the pump; engage the power take-off smoothly to avoid sudden impact on the hydraulic system.

• Switch between water mode and foam mode only after stopping the pump to protect the proportioning valve.

• Do not run the pump without water for more than 3 minutes to prevent seal burning.

Regular Maintenance

1. Weekly: Check tank tightness, clean the water filter and foam pipeline filter, test the rotation of the fire monitor.

2. Monthly: Replace hydraulic oil, inspect the sealing rings of the pump and all ball valves, drain residual liquid inside the tank to prevent corrosion.

3. Quarterly: Calibrate the foam mixing ratio, conduct full-pressure water injection test on the tank.

4. Long-term parking: Empty all liquid inside tanks, coat the foam pipeline with anti-rust oil, and park the vehicle in a dry warehouse.

   Strict maintenance can extend the service life of the pump and pipeline system to more than 8 years, greatly lowering later operating costs中国重汽.

8. Conclusion

For fire brigades, petrochemical enterprises, port operators and airport authorities across global emerging markets, this model is a cost-effective one-stop solution. Instead of purchasing two separate fire vehicles, you can cover all common fire scenarios with a single truck, cutting fleet investment while improving emergency response capability. It is your top choice for heavy-duty fire rescue equipment export procurement.
