III. Key Features & Benefits

1. Heavy-Duty HOWO 6×6 Chassis

Built on a SINOTRUK HOWO 6×6 all-wheel-drive chassis, this vehicle supports a gross vehicle weight of 30,000 kg, providing robust load capacity for water transportation and spraying operations in demanding environments. The all-wheel-drive configuration with balanced axle load distribution ensures superior driving stability across off-road terrains, muddy job sites, and during high-speed road travel.

2. High-Power Powertrain System

The WP12.400E32 inline 6-cylinder turbocharged inter-cooled diesel engine delivers 400 HP (294 kW) output, meets Euro III emission standards, and features a displacement of 11,596 ml. The FAST 12-speed manual transmission (12F+2R), combined with a 6×6 all-wheel-drive system and 4,325+1,350 mm wheelbase, ensures reliable power delivery for heavy-duty water transport and high-pressure spraying operations across diverse terrains.

3. High-Strength Tank Structure

Constructed using  Stainless Steel /Aluminum Alloy, the elliptical tank offers 20 CBM capacity (adjustable from 15 to 20 CBM) and is reinforced with internal baffles for surge suppression during transport. The elliptical design lowers the center of gravity, improving vehicle stability on uneven roads.

4. Core Pumping & Spraying System

The integrated WLOONG dual-function pump delivers a 90 m³/h flow rate with electro-hydraulic control, supporting front/rear sprinklers, side spraying, and a high-pressure water cannon with a 28 m range. Adjustable spray patterns include jet, mist, heavy rain, light rain, and drizzle, making it versatile for multiple applications.

5. Bottom Water Valve Assembly

· Four-Way Three-Position Ball Valve: Enables instant switching between suction, sprinkling, and firefighting modes — eliminating the need for multiple valves and simplifying operation.

· Flanged Ball Valves: Large-diameter design ensures minimal flow resistance, delivering high-efficiency water output during sprinkling and discharge operations.

· Fire Hose Couplings: Standard quick-connect fittings allow direct hydrant connection for ultra-fast tank filling and emergency fire response, significantly reducing setup time.

6. Front Spray Nozzle Assembly

· Dual Nozzle Design: Duckbill-shaped nozzles on both sides deliver high-pressure water in a fan or jet pattern, covering the full lane width for efficient road washing and dust suppression.

· Flow Control Valve: Central-mounted ball valve provides instant on/off control, allowing the operator to activate the front spray independently without affecting other watering functions.

7. Operational & Safety Features

· Self-priming capability with vertical suction height > 7 m for direct water intake from rivers, ponds, or natural sources

· Sprinkling width > 14 m for full-lane coverage in a single pass

· Rear work platform with 360° rotating water cannon

· Safety equipment includes fire hose couplings, gravity valve, and water level gauge

· Optional fire-fighting pump with 50 m range for emergency response applications

IV. Operating Principle

Front-Mounted Spray Bar

· Dual Nozzle Design: Duckbill-shaped nozzles on both sides deliver high-pressure water in a fan or jet pattern, spray width ≥ 14 m, flow rate 90 m³/h, for efficient road washing and dust suppression.

· Flow Control Valve: Central-mounted ball valve provides instant on/off control, enabling independent front spray operation without affecting rear sprinkling or water cannon functions.

· Protective Guard: Metal grille above nozzles shields radiator and underbody components from debris impact, ensuring durability in rugged working environments.

· Operational Efficiency: Wide-coverage design minimizes passes per lane, significantly improving cleaning productivity for municipal road maintenance.

Operating Features

· Self-Priming & Self-Discharging: Vertical suction height > 7 m for direct water intake from rivers, ponds, or other natural sources.

· Side & Rear Spraying: Side sprinklers plus rear work platform enable comprehensive coverage for dust suppression and road washing.

· High-Power Spray Pump: Equipped with WLOONG dual-function pump, fire hose couplings, gravity valve, and self-priming capability; supports pressurized discharge.

· Optional Fire Pump: Fire-fighting pump available with extended range up to 50 m for emergency response applications.

V. Applications

Municipal Street Cleaning & Dust Suppression

The HOWO 6×6 water wagon is ideal for municipal street washing and urban dust control. With a sprinkling width of over 14 m and a 90 m³/h flow rate, it covers full lanes in a single pass, reducing operation time and water consumption for city road maintenance departments.

Farmland Irrigation & Agricultural Water Transport

For agricultural applications, this 20 CBM water bowser efficiently transports irrigation water to farmland, orchards, and plantations. The self-priming system allows direct water intake from rivers and ponds, while the adjustable spray patterns support both broad irrigation and targeted watering.

Landscape Maintenance & Greening

The 360° rotating water cannon with adjustable mist-to-jet patterns makes this water tanker truck perfect for landscape maintenance, park greening, and highway median watering. The rear work platform provides a stable position for precise operator control.

Factory & Mining Dust Control

In industrial and mining environments where dust suppression is critical, the HOWO 6×6 off-road water truck delivers reliable performance on unpaved roads and rough terrain. The all-wheel-drive system ensures access to remote work sites, while the high-pressure cannon effectively settles airborne dust particles.

Emergency Firefighting

Equipped with fire hose couplings and an optional fire-fighting pump (50 m range), this water sprinkler truck doubles as an emergency firefighting vehicle, making it a valuable asset for industrial parks, mining camps, and remote communities without dedicated fire stations.

Main Applications

1. Fire-Fighting & Emergency Water Supply

The water tanker truck serves as a critical mobile water source for fire-fighting operations. In areas without fire hydrants or during large-scale emergencies, it rapidly delivers large volumes of water to the scene, supporting both initial attack and sustained firefighting efforts. Optional high-pressure water cannons enable long-range spraying for effective fire suppression.

2. Road Construction & Dust Suppression

On road construction and demolition sites, the water tanker truck humidifies the working surface to suppress airborne dust. This not only creates a cleaner and safer working environment but also helps meet environmental regulations and improves visibility for workers and equipment operators.

3. Agricultural Irrigation

For farmland and plantation areas lacking fixed irrigation infrastructure, the water tanker truck transports and distributes water directly to crops. Equipped with sprinkler bars or drip-irrigation connections, it provides targeted watering to support healthy crop growth and mitigate drought conditions.

4. Herbicide & Disinfectant Spraying

The tanker can be configured to spray herbicides, pesticides, or disinfectant solutions over designated areas. Its precise spray control ensures even coverage, helping farmers and municipalities control weeds, pests, and disease vectors while minimizing chemical waste.

5. Municipal & Environmental Services

Beyond the above, water tanker trucks are widely used for street cleaning, greenbelt watering, construction site water supply, and temporary water distribution during pipeline maintenance or natural disasters.
