The Dongfeng 8 m\u00b3 water tanker truck is a 4×2 water bowser that carries 8,000 litres of water and sprays it four ways: a front flush bar, a rear spray bar, side sprinklers and a rotating water cannon on the rear platform.<\/strong> It is built on a Dongfeng chassis with a 3,800 mm wheelbase, a choice of Cummins 125 hp, Cummins 140 hp or Yuchai 135 hp engines, and left-hand or right-hand drive. Typical jobs are road washing, dust control on construction and mining sites, watering parks and green belts, and emergency water supply.<\/p>\n

This guide covers the full specification, what each spraying system does, the options you can add, and how to order one for export.<\/p>\n

Tank Design: Why Baffles and Coating Matter<\/h2>\n

The tank is made from Q235 carbon steel, 4 mm thick. Inside, anti-surge baffles split the water into sections, so the load does not slam forward when the driver brakes or turns. This keeps the truck stable and reduces stress on the chassis frame.<\/p>\n

The tank is e-coated (electrophoresis) against rust inside and out, which matters when the truck carries water every day. A water level gauge on the front head shows how much is left. A rear ladder and a top guard rail give safe access to the manhole for cleaning and inspection.<\/p>\n

Four Ways to Spray Water<\/h2>\n

The truck has four outlets. Each one is meant for a different job, and you can run them separately.<\/p>\n

1. Front flush<\/h3>\n

A flush bar in front of the bumper washes the road surface and keeps dust down ahead of the truck. Some versions use an adjustable duckbill nozzle, so you can change the angle.<\/p>\n

2. Rear spray<\/h3>\n

The rear spray bar covers a width of at least 8 m. It is used for dust suppression, cooling road surfaces in hot weather and routine road maintenance.<\/p>\n

3. Side sprinklers<\/h3>\n

Sprinklers on both sides of the tank water green belts, roadside planting and lawns, covering a width of at least 14 m.<\/p>\n

4. Rotating water cannon<\/h3>\n

The cannon is mounted on the rear work platform and turns 360\u00b0. You can switch the spray pattern between a straight jet, heavy rain, light rain, drizzle and mist. Its range is 28 m or more, enough to reach trees, building walls and high billboards.<\/p>\n

Pump, Pipes and Valves<\/h2>\n

A dedicated high-flow sprinkler pump is standard. It is self-priming, so the truck can draw water from a river, pond or open tank with a suction lift of at least 7 m. A 40 or 50 fire pump can be fitted instead if you need higher pressure.<\/p>\n

The truck comes with two suction hoses, outlet piping, ball valves, a gravity-flow valve, a filter and a standard 65 mm fire hydrant inlet, so it can also fill directly from a hydrant. Longer hoses (3 m or 5 m) can be supplied.<\/p>\n
