The Portable Water Tank Trailer is an integrated, mobile water storage and operation unit consisting of a heavy-duty PE water tank, an independent diesel-powered water pump assembly, a swiveling high-pressure water cannon, and a dual-wheel towable chassis; it can be towed by tractors, pickup trucks, or SUVs. Combining multiple functions—such as water storage, dust suppression spraying, landscape irrigation, emergency firefighting, and site cleaning—it serves as a versatile mobile water supply solution for construction sites, forestry operations, farms, and rural communities.

Water Tank Trailer Overall Structure: 

Large-capacity PE water tank: One-piece rotationally molded white polyethylene water tank, corrosion-resistant, anti-aging, rust-free, resistant to high and low temperatures and not easy to crack; multiple capacity options available (1-5 tons), large-diameter top water inlet, bottom drain valve, drains accumulated water to prevent freezing, easy to clean.

Independent Diesel-Powered Pump Unit

Front-mounted diesel engine and high-pressure centrifugal pump assembly with a dedicated control panel. Operates independently of the towing vehicle, ensuring stable water supply whether stationary or in motion; features adjustable pressure and high flow rates.

360° Universal Fire Monitor

Adjustable vertical high-pressure water monitor capable of 360° horizontal rotation and free vertical tilting. Offers switchable spray modes (concentrated jet vs. mist spray), long-range projection, and wide coverage.

Dual-Wheel Towing Chassis

Heavy-duty, powder-coated carbon steel load-bearing frame with dual automotive-grade tubeless tires for smooth, shock-absorbing travel. Equipped with a standard tow hitch compatible with various towing vehicles and an optional parking brake; ensures stable operation on both rugged dirt tracks and paved roads.

Complete High-Pressure Water System

Features stainless steel high-pressure piping, flow control valves, and quick-connect hose fittings. Supports both wide-area spraying via the water monitor and targeted cleaning or irrigation/disinfection via an externally connected handheld spray gun.

Features of the Water Tank Trailer

1. Highly mobile and unrestricted access

Featuring a lightweight, towable design, it can be pulled by small vehicles. It accesses narrow roads, construction sites, and mountainous orchards where large water trucks cannot go, solving water supply challenges in remote areas.

2. Independent power for unrestricted operation

Powered by a self-contained diesel engine, it does not drain the towing vehicle's power and allows for immediate start/stop operation. It offers long-range high-pressure spraying and uniform atomization, ensuring high efficiency in dust suppression and irrigation.

3. Versatile, multi-scenario application

Construction: Dust suppression on site roads, watering spoil sites, and dust control in mining areas.

Agriculture & Forestry: Drought-relief irrigation for orchards and nurseries, pasture watering, and pest control.

Rural Safety: Basic emergency firefighting for villages and forest fire prevention/spraying.

Sanitation & Livestock: Cleaning factory roads, and washing, cooling, and disinfecting livestock facilities.

4. Durable, low-cost, and easy to maintain

The PE water tank is corrosion-free for its entire lifespan; diesel engine parts are widely available and easy to service. The unit boasts a low failure rate and economical fuel consumption, offering excellent long-term value.

5. User-friendly safety design

A single operator can adjust the water cannon's spray angle. The chassis features a stable center of gravity and a dual-wheel structure to prevent rollover. A bottom drain valve allows for complete emptying to prevent freezing damage in winter. High-pressure hoses are explosion-proof and durable, while the inlet allows for rapid refilling.

6. Customizable with direct-from-factory advantages

As a Chinese manufacturer, we offer customization options including tank capacity, single or dual-wheel chassis, diesel or electric pumps, optional mist cannons, and body color. We provide significant price advantages and support both domestic and international trade.
