The pure electric road maintenance vehicle is developed in response to market demands as a vehicle for road and urban appearance cleaning. It is suitable for sanitation work on urban roads, residential communities and other areas. Capable of high-pressure cleaning roads and sidewalks, it can effectively clean hard-to-reach sanitary areas and ground advertisements.
The water tank features a single-layer structure and is made of high-quality steel plates with anti-corrosion treatment on the inner wall. The auxiliary motor adopts stepless speed regulation, allowing the flow rate and pressure of the cleaning operation to be adjusted at any time.
Both high and low-pressure water pumps are electrically driven, and the flushing pressure is steplessly adjustable. The fixed-point cleaning device can swing in all directions, and the high-pressure resistant hand-held spray gun effectively cleans heavily soiled floors with oil stains. The front water spray boom is controlled by electric push rods, enabling a 15-degree left-rightrotation and a height adjustment range of 100 millimeters up and down, with a maximum cleaning width of 1.55 meters.
This road maintenance vehicle is built on a Class II pure electric chassis, retrofitted with a high-pressure water system, electrical system, front spraying mechanism, clean water tank and other components. The vehicle features a high degree of electrification. Multiple industrial linear actuators and rotary motors are deployed to execute cleaning operation movements. It is easy to operate and runs stably and reliably.
