Dongfeng 4X2 8t Foam Fire-Fighting Truck: Integrated Water & Foam System

Kailifeng Dongfeng D9 Foam Fire Engine

Extra-large capacity

In dealing with large - scale fires, "sustained combat capability" is crucial. The liquid - carrying capacity of this Kailifeng Dongfeng D9 foam fire engine reaches 7 cubic meters (5.2 cubic meters of water + 2.1 cubic meters of foam), which can meet the needs of long - term and high - intensity firefighting. The water tank is welded from high - quality carbon steel plates with a 4mm bottom plate, 3mm side plates and sealing plates. The internal anti - corrosion treatment ensures clean water quality. The foam tank is made of 304 stainless steel, with a 4mm bottom plate thickness, 3mm side plates and sealing plates. Its corrosion resistance far exceeds that of ordinary steel. 2.1 cubic meters of foam liquid is sufficient to cover the initial prevention and control of oil fires in an area of 500 square meters.

The CB10/40 normal pressure fire pump has a rated flow rate of 40L/s@1.0MPa, which means it can output 2.4 tons of water or foam mixture per minute. The matched PL8/32 fire monitor has a water range of ≥60 meters and a foam range of ≥48 meters. A 60-meter range is equivalent to the height of a 20-story building, enabling it to easily cover the high-altitude fire situations in large factories, warehouses and other buildings. With a horizontal 360° + pitching -35°~70° spraying angle, combined with the PH64 ring pump foam proportioner, it can efficiently complete either large-area water suppression or precise foam coverage.

High-power chassis + intelligent control

To drive a liquid-carrying capacity of 7 cubic meters and reach the scene quickly, strong power support is essential. This vehicle is equipped with a Dongfeng D9 National VI chassis, with an engine rated power of 169KW. The 4×2 drive type, combined with a wheelbase of 4700mm, enables the vehicle to reach a maximum speed of 105km/h even under full load, ensuring that it can "respond to an alarm immediately and arrive at the scene quickly".

In terms of control design, the cab adopts a flat - head, four - door, double - row structure. The seating layout is 3 people in the front row plus 3 people in the back row, which can meet the needs of a 6 - person combat team to set out simultaneously. Equipment such as a 100W siren and a power take - off control switch are centrally arranged in the driving area and within easy reach. The sandwich - type full - power power take - off is controlled by a solenoid valve, with a response time of ≤ 0.5 seconds. Coupled with a forced water - cooling system, it can stably output power even when working continuously. The electrical system is like the "rescue eyes in the sky". The 1.9 - meter - long row of LED warning lights can be seen from a distance. The 360° LED remote - controlled searchlight at the rear top can penetrate thick smoke and lock on to the fire source. Three sets of strobe lights and side - lighting lamps on both sides make night - time rescue as bright as day.

Scientific layout + durable knot

At the intense rescue scene, the efficiency of equipment retrieval directly affects the speed of the operation's deployment. The equipment box of this vehicle adopts a structure of "high-quality steel skeleton + oxidized aluminum alloy checkered plate". The front equipment box is equipped with 4 aluminum alloy rolling shutters, and the rear pump room has 1 each, to avoid interfering with command communication.

The equipment layout strictly follows the "actual combat logic": large equipment such as suction hoses and water hoses are placed in convenient positions and can be accessed within 2 movements while standing on the ground; frequently used equipment such as water distributors and foam guns are placed in zones according to the "combat formation" and are matched with ergonomic brackets. The tank is equipped with 2 liquid level indicators, manual sewage discharge valves and other equipment, enabling firefighters to keep track of the remaining amount of fire extinguishing agent in real time and avoiding decision-making being affected by information lag.
