Use Cases
Ideal for municipal dust control, highway and construction site cleaning, and landscape irrigation, this sprinkler truck (water bowser) handles both wide-area dust suppression and targeted high-pressure cleaning. Its self-priming and pressure-discharge functions make it equally useful for temporary water supply and emergency support on work sites.

Detailed Description
Built on the ZZ1257N4647B1 chassis, the Howo water truck features the WP10.380E22 380HP (National II) engine paired with an HW19710 gearbox and HW70 flange-type PTO for stable, high-torque transmission—great for sustained pump operation. The HW76 new-front-face cab with air conditioning provides operator comfort during long shifts, while Bosch steering and metal bumpers with lamp guards improve durability and safety. The vehicle comes with a 400L fuel tank and no ABS (built to spec).
The 20m³ tank is fabricated with 5mm shell and end plates and 3mm internal baffles to minimize liquid surge; it includes front spray, rear sprinkle, a high-pressure water gun, rear work platform and Hangzhou Weilong pump. The system supports self-priming, gravity flow and pressure discharge for flexible application as a sprinkler truck, water bowser or tanker — making it a practical choice for municipalities, contractors and rental fleets.
