3. Dimensions, Material & Design Philosophy
Design Philosophy: This road cleaning truck embodies a multi-functional design that maximizes utility across various sanitation tasks. The tandem rear axle provides exceptional stability and load-bearing capacity, while the dual-engine system allows independent operation of the driving and working functions, enhancing fuel efficiency and reducing wear on the main engine during stationary cleaning operations. The vehicle is engineered for all-in-one performance in municipal and industrial environments.
Construction Materials: The water tank is constructed from high-strength steel with anti-corrosion coating, ensuring durability and long service life. The frame features a reinforced heavy-duty structure capable of withstanding the stresses of off-road and urban operations. The high-pressure pump and piping are made of stainless steel and wear-resistant materials for reliability under continuous use.
Dimensions and Tank Details: The 13-cubic-meter tank is optimally sized for extended operation without frequent refilling. The tank is equipped with internal baffles to reduce water surge during transport. The vehicle features a rear platform with access ladders and safety rails for operator convenience. The high-pressure hose reel is positioned for easy access and rapid deployment.

4. Structural & Component Advantages
Engine and Transmission Advantages: The Longxi 350HP main engine delivers robust power for highway travel and hill climbing, while the Yuchai 102HP auxiliary engine independently drives the Pinfu 170 high-pressure pump, ensuring consistent water pressure for cleaning tasks without idling the main engine. This dual-power system significantly reduces fuel consumption and emissions during stationary operations. The transmission is matched to provide optimal torque for both on-road and off-road conditions.
Chassis and Axle Advantages: The 4350mm+1350mm tandem rear axle configuration provides superior load distribution and stability, essential for carrying full water tanks and operating on uneven terrain. The heavy-duty frame with reinforced cross-members ensures durability under heavy loads. The 11.00R20 steel radial tires offer excellent traction and puncture resistance on construction sites and rough roads.
Pump and Hydraulic System Advantages: The Pinfu 170 high-pressure pump delivers reliable water flow for road washing, flushing, and dust suppression. The system includes pressure regulation and safety valves to protect components. The auxiliary engine drive allows precise control of pump speed and pressure independent of vehicle speed.
Multi-Function Capability Advantages: The vehicle integrates multiple systems for spraying, flushing, and washing. It features front and side spray bars for wide-path road cleaning, a rear high-pressure nozzle for targeted flushing, and a dust suppression cannon for airborne particle control. These functions can be operated simultaneously or independently, maximizing productivity.
