HOWO 6x4 heavy rescue apparatus fire truck

The HOWO 6x4 heavy rescue apparatus fire truck is a professional vehicle with excellent firefighting performance. It is equipped with a 400-horsepower powerful engine and a 12-speed gearbox. It is powerful and responsive, can quickly reach the fire scene, and can easily pass through complex terrain. It is equipped with a 10-cubic-meter water tank and a 2-cubic-meter foam tank. The dual-media reserve is sufficient, and it supports water and foam dual-mode firefighting. The fire cannon has a long range and a large flow rate, and can accurately strike the fire source and efficiently cover and isolate. For different fire scenes, such as buildings, forests, oil tanks and hazardous chemical leaks, there are adaptive tactics that can be used for quick battles or precise attacks.

Modification basis and power structure

● Chassis gene: With the HOWO TX400 6×4 heavy-duty truck chassis as the core, it adopts a 4325+1350mm dual-stage composite wheelbase, a front axle load of 7 tons, and a rear double axle load of 18 tons. By optimizing the frame longitudinal beam structure (8mm high-strength steel + three-layer local reinforcement), the torsional strength under full load total mass is increased by 40%, ensuring the body stability under complex road conditions.

● Power heart: Equipped with WP10H400E62 400HP Euro 6 engine, displacement 9.5L, maximum torque 1900N·m (1200-1300rpm), with electronically controlled high-pressure common rail system, fuel injection pressure reaches 2200bar, power response speed increased by 25%, can meet the reliable operation under extreme working conditions

● Emission and economy: Adopt EGR+DOC+DPF+SCR post-treatment system, meet Euro 6d-TEMP standard, nitrogen oxide emission ≤0.4g/kWh, particulate matter ≤0.01g/kWh; match intelligent fuel saving mode (ECU automatically adjusts injection volume and valve timing), comprehensive fuel consumption is reduced by 12% compared with similar models.

● Transmission system: Sinotruk HW19712CL 12-speed full-synchronous gearbox: main box 6-speed + auxiliary box 2-speed structure, first gear ratio 13.11, highest gear ratio 0.78, support manual/automatic dual-mode switching; built-in forced lubrication system, gear oil circulation volume increased by 30%, ensuring a 200,000-kilometer maintenance-free cycle.

Upper system: three-dimensional combat layout of equipment-water tank-pump room

★ Front equipment room

●  Layout: Modular storage space, built-in fire emergency tools, including shovels, pickaxes, fire bags, bridge guards, etc., classified and fixed, easy to use.

●  Use: Suitable for initial rescue tasks such as demolition, plugging leaks, and road cleaning.

★  Middle tank system: water-foam coordinated fire extinguishing matrix

●  10m³ carbon steel water tank: The tank body is made of Q235A carbon steel, the inner wall is treated with epoxy resin for corrosion resistance, and the corrosion resistance life is ≥10 years; equipped with a liquid level sensor and an overflow valve, supporting stable operation in an environment of -20℃ to 50℃.

●  2m³ stainless steel foam tank: 304 stainless steel (thickness 4mm), built-in spiral agitator (speed 30-150rpm adjustable), ensures the accuracy of Class A/B foam mixing ratio ±2%; a breathing valve and wave-breaking plate are set on the top of the tank to suppress the shaking and impact of the foam liquid.

★ Rear pump room: high-pressure water-foam precise delivery center

● CB10/60 fire pump: rated flow 60L/s@1.0MPa, maximum suction depth 7m, supports dual-way water inlet (fire hydrant/natural water source); equipped with a vacuum water diversion system (water diversion time ≤35 seconds), and integrated overpressure protection device (automatic pressure relief when pressure ≥1.2MPa).

● Control panel: real-time monitoring of pump pressure, flow, liquid level and other parameters

● Fire extinguishing equipment matrix: equipped with 80mm fire hose (10 reels, length 20m/reel), water collector/water distributor/water filter, reducer (adaptable to DN50-DN150 pipe diameter), foam gun (flow rate 48L/s) and multi-function water gun (direct current/flowering/spray three modes).

★ Top PL8/48 fire monitor: long-range precision strike

● Performance parameters: flow rate 48L/s@1.0MPa, range ≥70m (water), ≥60m (foam), horizontal rotation angle ±360°, pitch angle -45° to +75°, support wired/wireless dual-mode remote control, response time ≤0.5 seconds

● Foam proportioning technology: through the linkage of gear pump and flow sensor, realize 3% or 6% foam liquid concentration automatic proportioning, error ≤±0.5%, stabilize the foam expansion rate at 6-8 times, cover thickness ≥8cm, oxygen isolation time extended to more than 45 minutes, effectively suppress re-ignition.
