III. Dimensions, Materials & Design Concept
Overall Dimensions: Built on a heavy-duty 8x4 chassis with strengthened rear axle (four U-bolts) and reinforced main frame, the vehicle provides exceptional stability for heavy-duty cleaning operations while maintaining maneuverability for its class. The hydraulic mounting and air suspension seat ensure operator comfort during transport and operation.
Tank Dimensions & Configuration: The 33-cubic-meter tank features a split-body design with approximately 10 cubic meters dedicated to fresh water and 23 cubic meters for sludge collection, separated by internal bulkheads with interconnection capability. The dump body design allows for efficient self-dumping of collected waste materials. The tank is equipped with wide platforms on both sides with guardrails for safe access during maintenance.
Material: The tank is constructed from 8 mm thick carbon steel plate, offering exceptional durability against impact, pressure, and corrosion from abrasive sludge and harsh waste materials. The strengthened main frame and reinforced subframe ensure structural integrity during self-dumping operations. The custom high-pressure hose features a wear-resistant design for extended service life.
Design Concept: The design philosophy centers on "German-Engineered Power with Maximum Capacity." Incorporating MAN technology from the engine to the chassis, this truck delivers European-level performance and reliability. The 33m³ capacity with dump body design maximizes productivity, while the 460 HP main engine and 420 HP auxiliary engine ensure ample power for simultaneous jetting and suction operations. Every component, from the reinforced rear axle to the hydraulic hose reel, is engineered for heavy-duty industrial applications where downtime is not an option.
IV. Detailed Structure & Component Advantages
Main Engine: Powered by a 460 HP diesel engine utilizing German MAN technology, this vehicle delivers exceptional horsepower and torque for the most demanding sewer cleaning and sludge extraction tasks. The MAN-technology engine is renowned for its fuel efficiency, reliability, and long service life in heavy-duty commercial vehicles, ensuring low operating costs and environmental compliance for fleet operators.
Auxiliary Engine System: A dedicated Weichai 420 HP auxiliary engine drives the SK-258 water-circulation vacuum pump independently. This split-power design allows the main 460 HP engine to focus on vehicle mobility while the auxiliary power unit provides massive suction capacity for extended vacuum operations without placing additional load on the primary engine – a critical feature for industrial-scale waste removal.
Transmission & Drivetrain: The heavy-duty transmission features a rear PTO for driving auxiliary systems, complementing the 8x4 drive configuration. This setup ensures exceptional traction and stability on uneven terrain, construction sites, and landfill access roads, while the reinforced rear axle with four U-bolts provides enhanced durability under heavy loads.
Chassis & Axles: The Howo 8x4 chassis features a strengthened rear axle with four U-bolts (vs. standard two), significantly improving load distribution and axle stability during heavy-duty operations. The hydraulic mounting system reduces vibration, protecting sensitive components and improving ride quality. The front axles and tandem rear axles are engineered to handle the massive 33-ton gross vehicle weight with ease.
Frame Strength: The strengthened main frame is specifically reinforced for dump body applications, resisting bending and twisting during self-dumping of dense sludge and solid waste. This reinforced construction ensures long-term structural integrity even under continuous heavy-duty use at landfill sites and waste treatment facilities.
Vacuum Pump System: The SK-258 water-circulation vacuum pump driven by the 420 HP Weichai auxiliary engine provides massive suction capacity for rapid sludge removal from sewer systems, septic tanks, and industrial holding tanks. The auxiliary engine ensures consistent, powerful suction independent of main engine speed, maximizing productivity during extended operations.
High-Pressure Pump System: The PF 350 high-pressure pump delivers 350 L/min flow for powerful water jetting to break through tough blockages, tree roots, and grease buildup in large-diameter sewer mains and storm drains. The 100 meters of custom 25 mm wear-resistant hose provides extended reach for deep pipeline cleaning.
Hydraulic Hose Reel: The hydraulically operated hose reel features left-right rotation, allowing 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 System: The comprehensive discharge system includes:
800 mm Hydraulic Rear Door: For rapid unloading of thick waste materials
150 mm & 100 mm Discharge Ball Valves: Versatile options for different waste types
100 mm Internal Suction Valve: For controlled waste extraction
