The Chengli municipal cleaning truck is a specialized sanitation vehicle designed for efficient street cleaning and urban environmental maintenance. It integrates sweeping, vacuuming, and dust suppression functions into a single compact unit, making it suitable for use on city roads, residential streets, industrial areas, and public squares. Its primary purpose is to remove dust, leaves, sand, litter, and other small debris from road surfaces, improving both cleanliness and air quality in urban environments.This cleaning truck is typically built on a reliable commercial vehicle chassis, with a reinforced frame to support sanitation equipment and water tanks. The sweeping system usually consists of side brushes and a central brush. The side brushes extend outward to reach the curb and pavement edges, while the central brush gathers debris toward the suction nozzle. All brushes are made from wear‑resistant materials to withstand continuous operation on rough road surfaces.A high‑performance vacuum system is installed behind the sweeping components. This system uses a powerful fan and an optimized air duct to create strong suction for lifting dust and debris into the hopper. The debris hopper is made of corrosion‑resistant steel and is designed for easy unloading at waste transfer stations or landfills. The capacity of the hopper is carefully matched to the vehicle size, allowing long operation times without frequent dumping.To control dust during sweeping, the vehicle is equipped with a water spraying system. Multiple nozzles are arranged near the brushes and suction mouth, spraying fine water mist to suppress flying dust. The water tank is usually made of anti‑corrosion material, and it can be filled from municipal hydrants or other clean water sources. Some models provide adjustable water flow to balance dust control with water conservation, depending on local conditions.The control system of the cleaning truck is centralized in the cab. The driver can operate the sweeping width, brush speed, water spray, suction strength, and dumping mechanism from an ergonomic control panel. Many vehicles are equipped with hydraulic systems for lifting the hopper and adjusting the position of the brushes. Safety devices such as backup alarms, work lights, and reflective markings improve visibility during nighttime or low‑light operation.In terms of power, the cleaning truck is commonly driven by a diesel engine that powers both the vehicle and the auxiliary cleaning systems through a power take‑off device. Some newer versions adopt low‑emission or alternative power solutions to meet stricter environmental regulations, reducing fuel consumption and exhaust emissions.Maintenance of the municipal cleaning truck is straightforward. Access doors and inspection hatches are provided for convenient cleaning of filters, ducts, and brushes. Regular servicing extends the life of key components and ensures stable performance. With its combination of mechanical sweeping, powerful suction, and effective dust suppression, this type of cleaning truck plays a vital role in modern urban sanitation, helping to maintain clean, safe, and attractive public spaces.
