The HOWO TX 300HP Water Fire protection truck is equipped with a WP10.300E22 engine and an HW19709XST transmission. The superstructure features an equipment compartment at the front for auxiliary firefighting gear, a 6-cubic-meter steel water tank in the middle, and a pump room at the rear. The pump room houses a CB10/60-RS fire pump with a flow rate of 60 L/s, along with a control panel and additional firefighting equipment. A PS8/40W water monitor is mounted on top of the tank. This vehicle is widely used for rapid response and efficient fire suppression in urban high-rise buildings, industrial facilities, and forest environments.

HOWO TX 4x2 double row water fire truck 

▶ Performance Advantages:

1. Rapid Power Response: Equipped with a 300HP engine and a 9-speed transmission, ensuring the vehicle is ready for immediate emergency deployment.

2. High Liquid Capacity: A 6-cubic-meter water tank supports extended, continuous operations, minimizing the need for frequent refilling.

3. Integrated Pump and Monitor System: The CB10/60 fire pump works in tandem with the PS8/40W fire monitor to deliver high-pressure, long-range streams—ideal for incidents such as high-rise building fires or chemical-related blazes.

4. Highly Integrated Equipment: Features organized storage compartments for gear and a centralized control panel in the pump room, significantly reducing preparation time for firefighting operations.

▶ Product Parameters:

▶ Fire-Extinguishing Principles:

The core fire-extinguishing mechanism of this Howo 4x2 water-tank fire truck centers on "water supply and high-pressure discharge." The vehicle is equipped with a large-capacity 6-cubic-meter water tank that serves as a reservoir for the extinguishing agent. During firefighting operations, a CB10/60 fire pump—driven by the chassis engine via a PTO driveshaft—draws water from the tank and pressurizes it. The pressurized water is then discharged at a flow rate of 60 L/s through fire hoses or a PS8/40W fire monitor. In "straight-stream" mode, the water is concentrated on the base of the fire to rapidly lower the temperature below the ignition point; in "spray" (fog/cone) mode, the coverage area of the water mist is expanded, utilizing heat absorption through evaporation and a smothering effect to cut off the oxygen supply. A control panel in the pump compartment allows for the monitoring of various parameters, enabling timely adjustments during operation.

▶ Piping System:

Tank pipeline material: Seamless steel pipes, connected to all components via flanges.

Tank outlet pipeline: Equipped with one DN125 tank outlet pipeline for water delivery from the tank to the fire pump. Fitted with one DN125 manual butterfly valve; the water tank and fire pump are connected through a DN125 flexible joint.

External suction pipeline: One DN125 external suction inlet is arranged at the rear of the fire pump for connecting a 125mm suction hose with a camlock coupling.

Tank filling pipeline: One DN65 filling port is provided on each of the left and right sides of the tank.

Discharge pipeline: The fire pump is equipped with one DN80 and one DN65 atmospheric discharge outlet on each side (left & right).

Drain pipeline: A drain valve is installed at the lowest point of the piping circuit to protect the fire pump and ball valves.

Cooling water pipeline: A cooling water circuit with ball valve is fitted to ensure the power take-off (PTO) operates reliably under complex working conditions.
