As a high-end truck chassis developed by China National Heavy Duty Truck Group (CNHTC) using imported MAN technology from Germany, SITRAK has not only made inroads into the premium logistics vehicle market but also expanded deeply into the field of specialized firefighting vehicles. A variety of firefighting vehicles with different functions have been developed based on the SITRAK C7H chassis.
Fire trucks are different from ordinary logistics vehicles. They require complex and precise onboard equipment and often operate under full load for extended periods during rescue missions, placing extremely high demands on the overall vehicle performance.
Since the rollout of the first SITRAK truck, its market positioning has been set for high-end logistics and premium special-purpose vehicle chassis. Especially in the firefighting sector, everything from the engine, transmission, and axles to the cab is built in strict accordance with German MAN’s European technical standards, with final product quality subject to approval by the MAN-SITRAK product audit team.
A firefighting vehicle chassis must not only be highly reliable but also leave sufficient space for mounting specialized equipment. During chassis development, SITRAK implemented a scientifically rational wiring harness layout, multiple reserved spaces, and a frame reinforced with large-span cross-member linking plates to ensure even stress distribution. Most of the chassis components are sourced from MAN’s original suppliers, ensuring exceptional reliability. The chassis longitudinal beams adopt standardized hole spacing, facilitating modular arrangement and optional installation of various components for different wheelbases.
The cab is a domestically produced TG series cab that meets the European ECE R29 truck cab strength standards. It features double-layer steel structures for the roof, side walls, and rear walls, all welded integrally. The floor includes both longitudinal beams and transverse reinforcing beams, offering high strength to protect onboard equipment and personnel. To meet the rising demand for intelligent firefighting vehicles, multiple interface ports have been reserved within the cab to fully support refitting enterprises. Currently, the C7H-M and C7H-M (flat roof) cab options are available, and a four-door cab specifically designed for firefighting is under development.
At the heart of the SITRAK’s stable power output is the MAN-technology MC series engine, with displacements ranging from 7L to 13L and power ratings between 350 and 540 hp, fully meeting the power needs of various firefighting vehicles. The onboard equipment is also powered by the engine, with full-power PTOs (power take-offs) reserved on MC engines to ensure sufficient output for auxiliary systems. Paired with imported ZF transmissions and MAN axles, the firefighting trucks built on this chassis achieve dependable operational readiness.
The SITRAK firefighting chassis, carrying MAN‘s engineering DNA, has begun making a strong impression in the firefighting sector. Its flexible and reliable configurations are winning over more and more manufacturers.
In recent years, major fires caused by the storage and transport of hazardous chemicals have occurred frequently. Unlike typical fires, chemical fires involve flammable and explosive substances that burn quickly and spread widely. Chemical storage facilities are large in both size and capacity, requiring sustained and large-scale delivery of water, foam, and dry powder for suppression. These incidents demand much higher performance from firefighting equipment.
To address such needs, a suite of firefighting equipment based on the SITRAKC7H chassis was developed, optimized in terms of foam/water discharge, continuous supply, and operation duration. This suite includes an ultra-heavy-duty 10-meter elevated foam spray fire truck, an ultra-heavy-duty foam fire truck, a large-capacity dry powder fire truck, a self-loading long-distance water supply system, a rapid boom-mounted long-distance water supply system, and a marshland-adapted long-distance water supply system.
Within this system, water can be supplied either by the pumping fire truck or drawn from nearby sources such as rivers, with pressurization. If the distance is too great, hose-laying trucks can deploy hoses up to 3 kilometers long. A multifunctional water distributor then continuously delivers water to all the fire trucks.
The ultra-heavy-duty 10-meter elevated foam fire truck is a powerful, specialized tool for tackling petrochemical fires, equipped with high-flow pumps and fire monitors. Its fire monitor can deliver up to 400 liters per second, with a shooting range of over 150 meters and an elevation greater than 10 meters. Working in conjunction with the ultra-heavy-duty foam fire truck, the system can deliver high-volume foam or water from both high and low positions, forming a coordinated assault on the fire.
The large-capacity dry powder fire truck can carry 6 tons of dry powder and 2,400 liters of nitrogen, with a dry powder cannon range of over 38 meters and a discharge rate greater than 35 kg/s, allowing for faster response and greater extinguishing coverage.
To deal with hazardous chemical accidents, a special emergency response fire truck has been developed. It is mainly intended for large-scale ammonia leakage incidents, minimizing harm to personnel and the environment. It can also perform decontamination during general chemical accidents and assist with regular firefighting missions.
Additionally, a new aerial ladder fire truck has been introduced for extinguishing fires in high-rise buildings and rescuing trapped individuals.
