The road maintenance vehicle is a special operation vehicle newly developed by our company for the cleaning and maintenance of urban pedestrian roads, as well as the cleaning of stall roads and small advertisements. It has many functions, such as linear high-pressure water curtain cleaning, cylindrical single point cleaning, manual spray gun cleaning, manual push nozzle cleaning, etc. The vehicle has the advantages of full electric automatic control, small working radius, good accessibility, clean cleaning, etc., so it is widely used in the cleaning and maintenance of narrow streets, sidewalks, pedestrian streets, squares and other places that are difficult for medium and large vehicles to enter. Small road maintenance vehicles have a wide range of functions in urban cleaning and maintenance. Their functions are mainly used to clean all kinds of corners of the city that are not easy to clean. They effectively fill the gap left by medium and large cleaning equipment and are a useful supplement to medium and large cleaning equipment.

The working principle of the road maintenance vehicle is: use the high-pressure water generated by the high-pressure water pump to spray out through the high-pressure nozzle of the water spray frame, use the kinetic energy of the high-pressure water flow to clean in the way of high pressure and low flow, strong decontamination, efficient water saving, and can clean the old stains on the road surface; Or spray high-pressure water through the left (right) corner to clean the kerb, sidewalk and guardrail isolation area; High pressure spray gun can also be used to clean road signs, billboards, elevated roads, etc; The spray system has powerful functions of spray dust reduction, spraying air disinfectant and adjusting air humidity. The high-pressure water pump is driven by auxiliary engine → reducer → coupling; The low-pressure waterway system adopts a two-stage impeller centrifugal pump, which has high efficiency, large watering width and long range of water gun. It can also be equipped with greening irrigation and self-priming functions. The low-pressure water pump is directly driven by the chassis transmission power take-off through the transmission shaft.
