3. Dimensions, Material & Design Philosophy

• Design Philosophy: This cleaning and suction truck features a separated tank design with an internal partition bulkhead that completely isolates the fresh water compartment from the sludge compartment. This prevents cross-contamination during dual operations. The innovative M-type front bumper integrates large-capacity tool boxes for convenient on-site tool storage and maintenance access.

• Construction Materials: The sludge tank interior is lined with thin stainless steel plates providing excellent corrosion resistance against acidic and alkaline waste materials. The main tank structure and frame are constructed from high-strength carbon steel, featuring a reinforced double-layer frame with 8mm plus 8mm steel plates and 300mm section height for maximum durability.

• Tank Details and Dimensions: The tank system includes two triple-claw manholes with one for the water compartment and one for the sludge compartment. Internal access ladders are installed for maintenance and cleaning operations. A 700mm hydraulic rear cover enables rapid sludge discharge. The working platform is fully covered with anti-skid patterned steel plates and equipped with safety guardrails for complete operator protection.

4. Structural & Component Advantages

• Engine and Transmission Advantages: Powered by the Yuchai 500HP National VI engine, this cleaning and suction truck delivers exceptional torque output for heavy-load suction and high-pressure cleaning tasks. The 12JSDX220TA-B manual transmission, combined with the Φ430 pull-type clutch, ensures smooth power delivery, reliable gear engagement, and optimized fuel consumption across varying operational speeds and load conditions.

• Chassis and Axle Advantages: The 8x4 configuration, commonly known as front four rear eight in the industry, utilizes 2 x 457 cast steel front axles and 2 x 457 cast steel rear axles with a 4.875 ratio. This setup is mounted on a reinforced 300mm double-layer frame, providing exceptional load-bearing capacity and stability when operating on rough terrain or crossing obstacles.

• Pump and Vacuum System Advantages: The standard Pinfl 620 high-pressure pump delivers powerful water flow for pipeline cleaning applications. Optional systems include the 258 water circulation pump, the SK-20 water circulation pump with reverse discharge function, and a specialized grouting pump set for construction applications. The air-blowing-water system significantly enhances pipeline clearing efficiency during operation.

• Driver Comfort and Safety Advantages: The H73D cab features full air suspension for reduced driver fatigue during long working hours. Equipment includes LCD instruments, electrically heated rearview mirrors, and a multi-function steering wheel with cruise control. Safety systems include WABCO brake valves, ABS anti-lock braking system, automatic adjust arms, and a reversing camera with MP5 display. A remote control unit is also available for convenient external operation.

5. Product Features & Chengli Group Advantages

• Operational Efficiency Features: The interconnected tank design allows the fresh water and sludge compartments to share resources through ball valves when needed, maximizing operational flexibility. The rear hydraulic hose reel is both foldable and extendable, equipped with 100 meters of 25mm high-pressure hose for extended reach into pipeline systems.

• Advanced Configuration Options: This model supports multiple specialized configurations including the Pinfl 620 high-pressure pump, Weichai secondary engine options, various grouting pump sets, and complete remote control systems. These options make the vehicle adaptable to diverse municipal sanitation needs and industrial cleaning requirements.
