III. Dimensions, Materials & Design Concept
Overall Dimensions: The vehicle is built on a 4,350 + 1,350 mm wheelbase configuration, providing excellent maneuverability in urban environments while maintaining stability for heavy-duty operations at job sites.
Tank Dimensions & Configuration: The 22-cubic-meter tank features a split-body design with two compartments separated by an 8 mm thick bulkhead: approximately 5 cubic meters dedicated to fresh water and 17 cubic meters for sludge collection. The compartments are connected via ball valves, allowing operational flexibility to adjust water-to-waste ratios as needed for specific cleaning tasks.
Material: The tank is constructed from 8 mm thick carbon steel plate, offering exceptional durability against impact, pressure, and corrosion from abrasive sludge and waste materials. The tank interior features stainless steel floor lining to resist wear from heavy debris and facilitate easier cleaning. The subframe is reinforced with 8 mm heavy-duty material to support self-dumping operations.
Design Concept: The design philosophy centers on "Original Quality with Maximum Value." Every component, from the Dongfeng original chassis to the 8 mm tank construction and hydraulic rear head, is engineered to deliver reliable performance at a competitive price point. The split-tank design with ball valve interconnection provides operational versatility, while the hydraulically operated rear head and 600 mm discharge port ensure efficient waste unloading – making this an ideal choice for budget-conscious buyers who refuse to compromise on essential features.
IV. Detailed Structure & Component Advantages
Engine: Powered by the upgraded Longqing 300 HP diesel engine, meeting stringent Euro VI B emission standards. This fuel-efficient powerplant delivers consistent torque for demanding suction tasks and high-pressure jetting while maintaining excellent fuel economy and environmental compliance for fleet operators concerned with operating costs and emissions regulations.
Transmission: Equipped with a Fast 8-speed gearbox, this truck offers exceptional versatility for diverse driving conditions. The 8-speed transmission provides low-range power for challenging off-road environments and construction sites, while overdrive gearing enables efficient highway travel between project locations – a perfect match for the Longqing engine's power curve.
Chassis & Axles: The DFH1250B chassis is specifically engineered for rear twin axle applications, with reinforced front axle and tandem rear axles designed to handle the 22-ton payload capacity with ease. The 4,350 + 1,350 mm wheelbase ensures optimal weight distribution between axles, providing stability during both transit and stationary vacuum extraction operations.
Heavy-Duty Subframe: The tank is mounted on an 8 mm heavy-duty subframe, specifically designed for self-dumping applications. This reinforced foundation ensures structural integrity during waste discharge and extends the vehicle's service life under continuous heavy-duty use.
Hydraulic Rear Head System: The rear head features hydraulic opening with 180-degree rotation capability for the hose reel. This innovative design allows operators to position the high-pressure hose at optimal angles for accessing manholes and drainage points from either side of the vehicle, significantly improving on-site efficiency and reducing setup time.
Discharge & Suction Ports:
600 mm Hydraulic Discharge Port: One 600 mm cement cover on the rear head for waste discharge, hydraulically operated for easy unloading
6-inch Emergency Bypass Valve: Side-mounted for operational flexibility
6-inch Rear Discharge Port: Standard configuration
100-inch Suction Inlet: Direct connection to tank top for rapid sludge extraction
