5. With front sprinkling function, it can be used not only for daily sprinkling, for humidification and dust reduction operations, but also for pavement cleaning operations. Low-pressure front cleaning and rear watering functions are optional.
6. Equipped with left and right center column side punching device, the nozzle can be adjusted.
The pure electric cleaning truck is an electric high-efficiency sanitation truck integrating the functions of road sweeping and high-pressure cleaning. It is a special truck product that has been increasingly welcomed by sanitation users in recent years. The truck has various functions such as road sweeping, road washing, road surface cleaning, curb and curb stone facade scrubbing, and spray dust reduction. The application of the truck has been widely used in cities, roads, and factories across the country. Its working principle is to clean the road surface with high-pressure, low-flow water and to use a fan to suck the sewage and garbage back into the truck-mounted garbage can. It is especially suitable for the cleaning of urban squares, road pavements, and curbs.
Shenzhen Dongfeng, leveraging over ten years of design and development experience in cleaning trucks, has developed the EQTXSBEVS pure electric cleaning truck based on the pure electric cargo truck chassis produced by Dongfeng Commercial Vehicle Co., Ltd. The truck uses a permanent magnet synchronous motor controlled by automobile-grade CAN bus technology for the upper power. The operational functions and specifications meet the requirements for cleaning operation, while the continuous operation time and operational efficiency reach the advanced level of similar products in China. The CATL Lithium Iron Phosphate Batteries matched with the truck are the lithium battery products with the largest sales volume and the best user reputation in China. Lithium iron phosphate batteries not only have stable high and low temperature performance and high cycle charge times but also feature stable charge and discharge characteristics and are less likely to catch fire.
Function Overview
The front part of the truck is equipped with left and right corner sprays. The middle section features a cleaning mechanism, suction nozzle, and high-pressure spray rod. The rear section includes a rear spray device and a handheld spray gun. Additionally, a high-pressure cleaning spray rod is installed inside the tank. The truck offers various functions including road surface cleaning, washing, dry cleaning, left and right corner spray cleaning, rear spray dust reduction, handheld spray gun cleaning, and self-cleaning of the dustbin.
Application Scope of Pure Electric Sweeping Truck
It is mainly used for cleaning, washing, and sweeping urban road pavements, squares, and road edges.
