With an 8 cubic meter tank capacity and equipped with a 60 meter air duct fog cannon powered by a 50 KW diesel generator set, this model delivers reliable performance for municipal and industrial operations. The vehicle features advanced pneumatic valve controls for front flush and rear sprinkle functions, operable directly from the cab for enhanced convenience and water conservation.

II. Core Specifications

III. Dimensions, Materials, and Design Concept

Exterior Dimensions: Standard Dongfeng D7 Duolika configuration

Tank Volume: 8 cubic meters full load capacity

Tank Material: High strength carbon steel with internal epoxy glass flake anti corrosion treatment, providing two years corrosion protection warranty

Design Concept:

The design philosophy centers on operational efficiency, water conservation, and maintenance simplicity. The vehicle incorporates pneumatic ball valves for front flush and rear sprinkle functions, controlled from the cab. This innovative design offers three key advantages: convenient operation allowing timely avoidance of pedestrians and special situations, prevention of water waste when the vehicle is stationary, and simplified tank maintenance due to the low position of front and rear pipelines. The internal tank features advanced epoxy glass flake anti corrosion treatment, significantly extending tank service life.

IV. Detailed Structure and Component Advantages

Engine Options:

Customers can choose between two reliable Euro VI compliant engines. The Dongfeng Chaochai 163 HP engine delivers robust performance for demanding applications. The Kunming Yunnei 150 HP engine provides excellent fuel efficiency for standard operations. Both options meet stringent emission standards while delivering consistent torque for pump operation.

Transmission Options:

The Chaochai engine configuration pairs with appropriate transmission matching for optimal performance. The Yunnei engine option features the Wanliyang 6 speed manual gearbox, offering smooth gear transitions and reliable torque delivery for both highway travel and low speed spraying operations.

Chassis and Axles:

Built on the proven Dongfeng D7 Duolika chassis with 3800 mm wheelbase, the vehicle features a 2.7 ton front axle and 5.5 ton rear axle engineered for 12 ton total mass capacity. The 8.25R20 steel wire tires deliver excellent load capacity, puncture resistance, and traction across various terrain types.

Braking System:

The vehicle is equipped with spring brake chambers, commonly known as, providing reliable parking braking capability. The air brake system ensures responsive stopping power during all operating conditions, enhanced by standard ABS for improved safety.

Fluid Handling System:

The vehicle is equipped with a standard 50/110 high power specialized water pump featuring self priming and self draining capabilities. The main pipeline is enlarged to front and rear three way configuration, resulting in increased water output and improved working pressure for all spraying functions. This enhanced flow design ensures optimal performance for front flush, rear sprinkle, side spray, and water cannon operations.

Fog Cannon System:

The rear work platform accommodates the ZX-60A fog cannon powered by a dedicated 50 KW four cylinder diesel generator set. This advanced system includes a 7.5 KW water pump and an 18.5 KW fan motor with aluminum alloy fan blades. The integration of high quality components ensures exceptional product stability and extended service life.

V. Product Features and Manufacturer Advantages

Standard Operating Functions:

Front flush delivers high pressure forward jets for effective road washing. Rear sprinkle provides wide angle coverage for large area applications. Side spray enables targeted irrigation for绿化带 and roadside vegetation. The water cannon functions as an adjustable high pressure monitor for long range spraying.

Advanced Pneumatic Control System:

The front flush and rear sprinkle functions utilize pneumatic ball valves operated from the cab. This system provides convenient operation for timely pedestrian avoidance, prevents water waste when stationary, and simplifies maintenance through accessible pipeline positioning.

Fog Cannon Specifications:

The ZX-60A fog cannon delivers a 60 meter spray distance under indoor static wind conditions. Actual field range varies based on humidity, temperature, wind speed, and other weather factors, with some evaporation occurring in arid environments. The system can be operated via wireless remote control within 100 meters or manually. The fog cannon is designed for dual purpose use, effectively functioning for both pesticide application and dust suppression.

Operator Environment:

The cab includes factory installed air conditioning for comfortable operation in all climates. Power windows and central door locking add convenience. Automatic headlight adjustment and ABS enhance safety during all operating conditions. The spring brake system provides secure parking capability on gradients.
