3. Dimensions, Material & Design Concept

• External Dimensions (L×W×H): Approximately 10,000mm × 2,550mm × 3,350mm (customizable based on configuration)

• Tank Dimensions: The tank features an elliptical cross-section design to lower the vehicle's center of gravity, ensuring stability during cornering on fully loaded operations.

• Material: The tank body is constructed from standard Q235 carbon steel with automated welding technology. The enhanced welding process ensures seamless joints, preventing leaks and extending service life.

• Design Concept: The D530-VR cab combines functionality with driver comfort. The semi-sleeper design allows for long-distance operation without driver fatigue, while the standard roof maintains low overall height for urban clearance requirements.

4. Detailed Structure & Component Advantages

• Engine & Drivetrain: Equipped with the DDi260HP diesel engine, this vehicle delivers exceptional torque output while maintaining fuel efficiency through advanced common rail technology. The engine is specifically tuned for heavy-duty applications, providing reliable power for both road transport and stationary spraying operations.

• Transmission System: The Dachi 7-speed manual transmission (DC7J120TA) features optimized gear ratios for both highway cruising and low-speed spraying operations. The integrated PTO allows the engine to power the water pump without vehicle movement.

• Chassis & Suspension: The 4350+1350mm wheelbase provides excellent stability for the 22-ton water tank. The combination of a 4.5-ton front axle and dual 10-ton rear axles ensures even weight distribution and superior load capacity, while the 280x80x(4+4)mm double-layer frame offers exceptional structural rigidity for heavy-duty applications.

• Braking System: Equipped with an advanced air braking system, ensuring safe operation even under maximum load conditions.

5. Product Features & Chengli Group Advantages

• Superior Water System: The vehicle is fitted with a heavy-duty special sprinkler pump, supporting both self-priming and self-discharge functions. The fully equipped spraying system includes front flushing, rear sprinkling, side spraying, and high-position flower sprinklers for versatile applications.

• Enhanced Pipeline Design: The main pipeline has been intentionally thickened to ensure consistent water pressure across all spraying functions. Large-diameter ball valves throughout the system provide reliable flow control, while the straight-through ball valve type fire interface enables emergency firefighting connections.

• Advanced Spraying Capabilities: The rear large working platform integrates a 30-meter mist cannon for atomized dust suppression and a high-pressure water cannon for long-distance jet stream applications. The mist cannon features adjustable spray angles and particle size for different dust control requirements.

• Operator Convenience: The cab comes standard with factory-installed air conditioning, central door locking, and a driving recorder. While featuring a mechanical seat, the cabin layout prioritizes ergonomics for reduced operator fatigue during extended shifts.

• Manufacturer Advantage (Chengli Group): As a leading special purpose vehicle manufacturer in China, Chengli Group implements strict quality control measures throughout the production process. Each vehicle undergoes comprehensive testing before delivery, ensuring reliability and performance. Our extensive service network provides prompt after-sales support and readily available spare parts.

• Fuel System: The 280L large steel fuel tank enables extended operation without frequent refueling, improving work efficiency for remote job sites.

• Customization Options: While this model features a 22-ton tank with 30-meter mist cannon, various customizations are available, including extended cannon ranges (up to 80 meters), anti-corrosion tank lining for chemical applications, and additional monitoring systems for precise spraying control.
