III. Dimensions, Materials & Design Concept
Overall Dimensions: Exact measurements can be customized based on configuration, but the vehicle is engineered for optimal maneuverability in narrow urban streets and confined job sites.
Tank Dimensions: The tank features a circular or elliptical cross-section designed to withstand internal pressure, with reinforced baffles to reduce liquid surge during transit. The 12.5 cubic meter tank is coated for corrosion resistance.
Material: Constructed from high-strength carbon steel with anti-corrosion coating, ensuring durability against abrasive and acidic waste materials commonly found in sewer systems. Stainless steel option is also available.
Design Concept: The design prioritizes dual-purpose efficiency. It integrates the high-pressure jetting reel and vacuum boom seamlessly into one unit, minimizing the footprint while maximizing functionality for single-operator use. This combination sewer cleaning vehicle is built for easy maintenance and long service life.
IV. Detailed Structure & Component Advantages
Engine: Powered by the reliable Yuchai 170 HP engine, it provides a perfect balance of high torque for heavy suction tasks and fuel efficiency for transit, meeting stringent emission standards. This Yuchai diesel engine is trusted worldwide for its durability and performance.
Transmission: The 8-speed gearbox offers a wide ratio range, delivering low-speed crawling power for tough cleaning jobs and comfortable high-speed cruising for travel between sites. This 8-speed manual transmission ensures optimal power delivery to match operating conditions.
Front & Rear Axles: The reinforced Dongfeng chassis is engineered for heavy loads. The front axle is rated for heavy steering stress, while the robust rear axle ensures stable load distribution, perfectly supporting the 12.5-ton gross vehicle weight. This heavy-duty chassis provides a solid foundation for demanding daily tasks.
Hydraulic System: The system is designed for simultaneous or independent operation of the vacuum pump and boom, allowing the operator to adjust power based on real-time requirements. This operational flexibility enhances productivity on the job site.
V. Product Features & CLW Group Advantages
High-Efficiency Pump System: The combination of a PF 215 high-pressure pump for water jetting to break up debris and a 12 liters/second water-cooled vacuum pump for powerful sludge suction ensures thorough cleaning in a single pass. This integrated high-pressure jetting and vacuum system is the core of the truck's superior performance.
Durability & Safety: Features include a rust-proof tank interior, heavy-duty pipe clamps, and reinforced mudguards to ensure longevity even in harsh working conditions. The anti-corrosion treatment significantly extends the operational life of the tank.
