BRIEF

The HOWO 6×6 20,000 Liters Water Sprinkler Truck is a heavy-duty, all-terrain water transportation solution engineered for demanding water delivery, dust suppression, road washing, and firefighting applications. Built on the legendary SINOTRUK HOWO 6×6 all-wheel-drive chassis—a platform renowned for its outstanding durability and off-road capability—this truck delivers exceptional traction and stability on rough, uneven, and remote terrain where conventional 4×2 or 6×4 water trucks cannot operate. Equipped with a massive 20,000-liter water tank, it supports extended working hours with fewer refill stops, making it an ideal solution for mining operations, construction projects, agricultural irrigation, municipal dust control, and emergency firefighting throughout the Philippines and other developing markets.

Powering the truck is the proven SINOTRUK WD615.47 diesel engine, producing 371 HP (273 kW) and a peak torque of 1,500 N·m between 1,100–1,600 rpm, delivering strong low-speed pulling power for heavy loads and challenging off-road conditions. The 6×6 all-wheel-drive drivetrain, combined with generous ground clearance, enables confident operation across mud, sand, steep gradients, and rocky terrain. The HW19710 10-speed manual transmission (10F+2R) provides smooth and precise power delivery, while the robust STR front axle and ST16 rear axles ensure excellent load-carrying capability. Inside, the spacious HW76 cab features air conditioning, electric windows, and an air-suspension driver’s seat, providing superior comfort for long-distance transportation and demanding field operations.

A key highlight of this truck is its 20,000-liter elliptical water tank, manufactured from 5 mm carbon steel and treated with an anti-corrosion internal coating to ensure long-term durability and water quality. The tank is paired with a high-performance water pump, supporting front flushing, rear sprinkling, side spraying, and a rear-mounted high-pressure water cannon for versatile municipal and industrial applications. The complete water system also includes air-operated front and rear sprinkler valves, a 25-meter rear hose reel, self-priming water suction from open water sources, and a dedicated firefighting connection for emergency response. Fully equipped with PTO, manhole, hose boxes, suction pipes, and an access ladder, this water sprinkler truck is ready for immediate deployment in road cleaning, dust suppression, construction site watering, agricultural irrigation, municipal water supply, and disaster relief operations.
