This is an 8×4 model developed specifically for the transportation of hazardous materials such as gasoline and diesel. It is based on the latest generation heavy-duty truck cab T709 from Dongfeng Special Vehicle Company and is equipped with a Dongfeng Cummins ISL 8.9-liter, 315-horsepower engine that meets EURO V emission standards.
One of its most notable features is the use of air suspension on both drive axles, allowing for a maximum gross vehicle weight of up to 32 tons, 1 ton more than conventional models with steel leaf spring suspension.
The Dongfeng T7 8×4 31 CBM fuel tanker lorry also incorporates a range of lightweight technologies and materials, including aluminum alloy wheels, aluminum-magnesium alloy fuel tank, air storage tanks, aluminum transmission housing, high-strength steel chassis, variable-section multi-leaf front suspension, and an aluminum alloy tank body. These features reduce the curb weight, creating more capacity for a larger tank and greater load, ultimately boosting operator revenue.
● Cab: Minimal Interior Changes
This new model uses the T709W cab, which is the standard cab for the Dongfeng T7 series. Unlike the regular models, this one features a yellow “Danger” warning sign on the roof to indicate it’s a hazardous materials vehicle.
It is equipped with a lightweight aluminum alloy tank body with a volume of 30.5 cubic meters, making it suitable for transporting gasoline and diesel.
This is a high-roof version. The cab interior uses a light-over-dark color scheme, and the driver’s seat features air suspension for improved comfort.
The interior layout remains largely unchanged from previous models, with a gray and black color palette. The fabric-covered seats offer average comfort, and there is a spacious double bunk bed setup behind the seats.
The center console is designed in a wraparound style with a simple button layout. It includes a driving recorder, LCD screen, air conditioning, and more.
The instrument panel retains the traditional layout, with speedometer and tachometer on the left and right, and fuel, water temperature, and air pressure gauges positioned below.
● 4 EURO V Engine Options and Extensive Lightweight Design
In terms of powertrain, this Dongfeng T7 8×4 31 CBM fuel tanker lorry offers 4 engine options. The unit shown is equipped with the ISL8.9-315E50A engine that complies with EURO V emission standards and is paired with a Fast 9-speed manual transmission.
The front axle uses a variable-section three-leaf spring suspension system. The exhaust pipe is front-mounted and fitted with a spark arrestor.
As a hazardous materials transport vehicle, the front wheels are equipped with disc brakes for improved heat dissipation.
The rear suspension adopts a variable stiffness air suspension system, which offers better handling stability, ride comfort, and braking performance—ideal for the hazardous goods transport industry.
Additionally, the aluminum alloy air tanks, battery, and urea tank are all integrated to maximize space utilization.
It comes fitted with 12R22.5 tires and aluminum alloy wheels manufactured by Zhengxing.
Thanks to the variable stiffness air suspension system, the Dongfeng T7 8×4 31 CBM fuel tanker lorry delivers superior driving performance, including enhanced handling, comfort, and braking efficiency. This setup also reduces dynamic loads on the road during driving and braking, effectively minimizing tire wear—ideal for hazardous goods transport.
Beyond excellent driving characteristics, the vehicle also includes numerous safety features: Disc brakes on the front axle, a mandatory speed limiter, ABS anti-lock braking system, spark arrestor in the muffler, dynamic driving recorder, and WABCO braking components—all designed to ensure maximum safety during transport.
In summary, this is a highly competitive product in the hazardous materials transportation sector.
