The Dongfeng rear double-axle refueling truck is a specialized fuel transport and dispensing vehicle designed for reliable operation in a wide range of working conditions. It is built on a robust heavy-duty chassis with a rear double-axle configuration, providing enhanced load-carrying capacity, good stability, and balanced weight distribution when the tank is fully loaded with fuel. This layout also improves traction and braking performance, especially on long-distance routes or uneven roads.The vehicle is typically equipped with a diesel engine offering sufficient horsepower and torque to handle both highway speeds and frequent stop-and-go operations at industrial sites, construction areas, or fuel depots. A manual or optional automatic transmission allows flexible gear selection and smooth power delivery. The steering system and braking system are designed for safety and control, often featuring air brakes and auxiliary braking functions to ensure effective stopping power when fully loaded.At the core of the refueling truck is its cylindrical or oval tank, manufactured from high-quality carbon steel or optional aluminum alloy. The tank is usually divided into multiple compartments, allowing the transport of different fuel grades in one trip and reducing liquid sloshing. Each compartment is fitted with manholes, breathing valves, and anti-wave baffles to enhance safety and stability. An integrated grounding system and anti-static devices help minimize the risk of sparks during loading and unloading operations.The refueling system consists of a fuel pump, flow meter, control valves, and refueling hose assembly. The pump can be driven mechanically by the vehicle’s power take-off or by an auxiliary motor. Accurate flow meters ensure precise measurement of delivered fuel, which is important for commercial transactions and inventory management. The refueling gun and hose reel are designed for convenient operation, allowing quick connection to machinery, vehicles, or storage tanks. Optional filter units can be added to improve fuel cleanliness.Safety features are a key part of the overall design. The truck often includes emergency shut-off valves, fire extinguishers, and clearly marked safety signage on the tank body. Reflective strips, side and rear protective guards, and non-slip walkways on top of the tank enhance operational safety, especially during night work or in busy yard environments. Some configurations may also provide an overload protection system and a liquid level gauge or alarm to prevent overfilling.The exterior can be customized with different paint schemes and markings according to local regulations and customer requirements. Additional options may include GPS tracking, fuel management systems, and an electronic invoice or ticket printer integrated with the flow meter. Together, these features make the Dongfeng rear double-axle refueling truck a practical and efficient solution for fuel transport and on-site refueling in logistics, mining, construction, agriculture, and other industries.
