III. Dimensions, Materials & Design Concept

External Dimensions (Box Size): The integrated debris bin and water tank are designed with a compact footprint of approximately 4,200 mm × 2,100 mm × 1,800 mm (13.8ft × 6.9ft × 5.9ft) to maximize maneuverability.
Material Quality: The debris bin is constructed from high-strength Q235 carbon steel and stainless steel, featuring reinforced bending resistance and thicknesses of up to 4 mm (0.16 inches) to withstand heavy abrasion.
Design Philosophy: Adhering to the principles of "Intelligent Control & Green Environmental Protection," the design focuses on negative pressure pure suction. It utilizes a vertical filter cartridge structure and a rear-mounted rolling brush suction port to ensure deep cleaning of roads without raising dust, adapting to complex working conditions with both dry and wet materials.

IV. Detailed Structure & Component Advantages

Engine & Transmission: The vehicle features a dual-engine configuration. The main Yunnei 150 HP engine ensures fuel-efficient driving, while the dedicated Cummins 140 HP auxiliary engine independently powers the operation system, ensuring powerful suction regardless of driving speed. The system integrates a heavy-duty continuously variable automatic clutch (with manual pump emergency system) to protect the auxiliary engine during start-stop cycles, reducing maintenance needs。
Front & Rear Axles (Chassis): Built on a reinforced Dongfeng double-layer frame, the front axle is rated at 2.5 tons and the rear axle at 6 tons, ensuring stable load-bearing even when the 1,320-gallon debris bin is full. The inclusion of oil-water separation and cut-off brakes (Spring Brakes) enhances safety on slopes.
Vacuum & Suction Structure: The core suction system uses a maintenance-free centrifugal fan (high negative pressure) combined with an advanced filtration unit. It features 8 large-capacity dust filter cartridges and imported pulse valves for automatic reverse pulse dust cleaning. This prevents filter clogging and maintains stable suction power during long hours of operation.
Hydraulic & Control System: Utilizing Schneider control switches and Hydreforce solenoid valve groups, the system supports (stepless speed regulation) for the sweeping brushes. The hydraulic system is finely tuned to operate the front two sweeping brushes and the rear rolling brush suction port smoothly.

V. Product Features & Chengli Group Advantages

Dual-Mode Operation (Dry & Wet):
- Dry Mode: Perfect for northern winters or water-scarce areas. It uses negative pressure and an 8-filter cartridge pulse system to collect dust without using water, preventing frozen roads。
- Wet Mode: Activated for summer use. The GTM high-pressure water pump forces water through (built-in high-pressure spray rods) inside the rear suction port to wash sticky mud and debris, functioning like a traditional street sweeper。
User-Oriented Design: The cabin is equipped with an original air conditioner, power steering, and a 6-speed gearbox for driver comfort. The rear features an LED arrow light for traffic safety, and a wireless remote control system allows for easy dumping of waste.
