How It Is Built

Manufacturing Process

Chassis is received from Sinotruk and inspected for correct wheelbase and drive configuration
Tank shell is cut, formed, and welded using automated and manual techniques to match specified shape and capacity
Internal clapboards are installed to reduce water surge during movement
Tank is pressure tested and leak tested before coating and final assembly
Anti-rust or non-toxic coating is applied inside the tank according to customer specification
Pump, piping, and spray systems are installed and aligned with the driveline
Front, rear, side, and green anti-aircraft gun nozzles are mounted and tested for flow and reach
Body is assembled onto the chassis with structural welding and final alignment
Truck is painted in customer-selected colour with logo applied free of charge
Final 100 percent test includes pump flow, spray reach, and system integrity before delivery

Comparison

How It Compares With the Alternatives

4x2 water truck with 10m³ tank	Lower load capacity and shorter range but better fuel efficiency and easier to drive in tight urban areas
Water truck with only rear sprinkler	Limited to cleaning only the back path; lacks front and side spray for full road coverage
Water truck with no high-pressure gun	Cannot reach tall trees or elevated green spaces; limited to ground-level watering

Operating Notes

Use Guide

Confirm tank capacity and material (carbon steel or stainless steel) before ordering based on water type
Use only the manhole or pump inlet for filling; keep air breather valve clear to prevent tank vacuum
Do not exceed 85 km/h to maintain stability and engine longevity under full load
Engage the pump only after the engine reaches operating temperature to avoid damage
Drain the tank and flush the system after use in freezing conditions to prevent ice damage
Free technical training is available at the factory before shipment for operators and maintenance staff
