ISUZU GIGA 4x2 12 CBM Water Sprinkler Truck for Sale – 12,000 L Road Watering Truck

★ A 12,000 L Isuzu GIGA 4x2 water bowser with front, side and rear spray plus a rear water cannon, built for road watering, dust control and landscaping.

Tank and Water System

▶ The tank is an elliptical carbon steel vessel with 4-5 mm shell, dished ends and internal anti-surge baffles. A large top manhole, a folding ladder and a top walkway with guard rails allow safe filling and inspection. The tank is painted inside and out with an anti-corrosion coating for long service in humid and coastal markets.

The water circuit uses a red-painted side pipe running along the tank, with two rear ball-valve outlets for hose connection and a drain valve at the lowest point. A level gauge on the tank and a low-water warning in the cab help the driver avoid running the pump dry during long watering runs.

Pump and Spray Equipment

▶ A PTO-driven centrifugal pump draws from the tank or self-primes from a pond, canal or hydrant. Typical flow is 800-1,200 L/min, enough for simultaneous front, side and rear spraying. The pump has a strainer, a relief valve and a priming system, and can be disengaged for road travel.

Spray equipment includes front and rear spray bars, side nozzles and a rear water cannon mounted on a swivelling pedestal. The cannon throws water 25-35 m for dust suppression and tree watering. The rear work platform, ladder and two ball-valve outlets let the operator connect hoses and control the spray from a safe position.

ISUZU GIGA Chassis

▶ The chassis is the ISUZU GIGA 4x2 heavy truck with the 6HK1 diesel engine, a manual gearbox and a single rear axle. The GIGA cab is wider and higher than the ELF, with air suspension seats, a tilt cab and a steel front bumper. The 4x2 layout keeps the truck simple and economical for municipal and depot work.

The cab seats three, with air conditioning, power windows and a car-style dashboard. Behind the cab, the chassis carries the tank, pump, toolbox and rear platform. The tank body is painted in a single bright color with reflective strips, side guards and rear warning lights for night work.

Applications and Export Options

▶ Typical work includes municipal road watering and washing, dust suppression at construction and mining sites, landscaping and park irrigation, tree and median watering, and fire-support water delivery. The 12,000 L capacity gives a long working range between refills, and the water cannon reaches high dust sources and tree crowns.

Options include a high-pressure washing bar, an independent engine-driven pump, a stainless steel tank, a water meter, a rotating beacon, a traffic arrow board and a rear sprinkler for dust roads. Left-hand drive is standard; right-hand drive, export packing and a spare-parts kit can be ordered. Production is quoted at 25-40 days.

Frequently Asked Questions

What is the tank capacity of this water sprinkler truck?

The tank is rated at 12 CBM, or 12,000 L. The elliptical shape keeps the centre of gravity low, and internal baffles reduce water surge during braking and turning.

How far does the water cannon reach?

The rear cannon throws water approximately 25-35 m, depending on pump flow, nozzle setting and wind. It is used for dust suppression, tree watering and washing high surfaces.

Can the pump fill the tank from a pond?

Yes. The self-priming centrifugal pump can draw from a pond, canal or hydrant with a suction lift of approximately 6-8 m. A strainer protects the pump from debris.
