Dongfeng Road Washing Truck Mounted Vacuum Street Sweeping Truck

The Dongfeng washing and sweeping vacuum truck typically employs a "sweeping-scouring-suction" working method, driven by a dual-engine system for superior power and efficiency:

• Dual Engine System:
  • Main Engine (Chassis): Powers the truck for movement and transport (e.g., Dongfeng Cummins engine, 130-190 HP).
  • Auxiliary Engine: A dedicated, smaller engine (e.g., Cummins technology or JMC) powers the sweeping and vacuum system (fan, water pump, hydraulic system), ensuring the cleaning mechanism runs at optimal power independent of the vehicle's speed.
• Sweeping: Two vertical side brushes rotate to loosen debris and sweep it from the curb and edges into the center of the truck's path. These brushes often have an automatic avoidance function to prevent damage from obstacles.
• Washing/Scouring:
  • Dust Suppression: Water spray nozzles are positioned near the side brushes to wet the road surface and suppress dust, preventing it from becoming airborne during the sweeping process.
  • High-Pressure Scouring: High-pressure water spray rods (often centrally mounted or built into the suction nozzle) blast stubborn dirt, mud, and stains from the road surface.
• Vacuum Suction: A powerful, high-volume fan creates a vacuum at a central suction nozzle. This nozzle immediately sucks up the mixture of dirt, debris, and water (sewage) into the dedicated refuse/dust bin. This rapid suction prevents wastewater from remaining on the road surface.

Sweeper Truck is an efficient environmental sanitation truck equipped with functions of sweeping road and high pressure cleaning road. It is widely used in city streets, road, station, square etc. Road cleaning truck are mainly composed of chassis, box (garbage box and water tank), sweep system, auxiliary engine, fan system, cleaning system, suction system, dust system, hydraulic system and electrical control system. The garbage box and water tank are made of super thick stainless steel plate. In order to prevent the early damage of the water tank and the garbage box because of corrosion, all the parts of the tank and the garbage box are made of super thick stainless steel, which greatly prolongs the service life of the whole truck.

A large area filter net is set at the top of the box to to reduce the clogging and to ensure the fluency of suction, the top of the box is set with a flow guide slot, which improves the dust effect, makes the garbage accumulation even and improves the effective capacity. Road sweeper truck is equipped with 2 brushes, the cleaning device has the function of automatic barrier protection or automatic reset. Road cleaning truck uses a unique hand pressure pump emergency lifting system: when the auxiliary engine fails and can not start the auxiliary engine, the garbage box is raised to facilitate the maintenance of the worker. The hydraulic valve group adopts the famous leading brands: the test pressure can reach 35MPa and the flow rate is 300L/Min. The dynamic, static and fatigue life of various industrial hydraulic valves and walking mechanical hydraulic valves can be accurately tested.

Using ultra wide mouthpiece, inside have long row of high pressure water spray bar is near the ground, have a big water impact force, can be direct make the sewage to suction port, efficient.

• Urban Street Cleaning:
  • Thorough cleaning of city streets, main roads, and highways to remove litter, dirt, sand, leaves, debris, and fine dust.
  • Improving the aesthetics and overall sanitation of urban areas.
• Municipal and Public Spaces:
  • Sweeping and washing of municipal squares, plazas, and city centers.
  • Cleaning pedestrian streets, sidewalks, and residential area roads.
  • Sanitation in parks and recreational areas, including parking lots and pathways.
• Industrial and Specialized Environments:
  • Cleaning surfaces in industrial parks, factories, and construction sites to remove heavy debris, rubble, and industrial dust.
  • Maintaining cleanliness at large facilities like airports (runways and taxiways) and port facilities (docks and loading bays).
  • Used in areas with significant dust production, such as cement plants, coal plants, and iron-works.
• Multi-functional Cleaning Tasks:
  • Pavement Cleaning and Scrubbing: The washing and high-pressure features are used to clean old stains and sticky dirt.
  • Dust Control and Suppression: The water spray system is crucial for dampening the surface and preventing secondary dust from flying up during the sweeping and vacuum process.
  • Garbage and Debris Collection: It efficiently collects and stores a wide range of debris, from fine particles to larger litter and gravel, in its specialized dirt/garbage hopper.
  • Auxiliary Washing: High-pressure reels or spray guns can be used for cleaning car bodies, general equipment, or localized road areas.

The Vacuum Sweeper Truck is mainly used for road dust cleaning and suction. It is widely used in seaports, coal mining places, urban roads, highways, airports, docks, Bridges, squares, residential areas etc to make the places. A Road Suction Truck can largely save labor cost and working time. To use the Sweeper Truck one hour can match a person sweeping the road all day!

The Dongfeng Road Washing Truck Mounted Vacuum Street Sweeping Truck is a multi-functional sanitation vehicle that integrates the functions of a sweeper, sprinkler, and high-pressure washing truck. It is designed for efficient and comprehensive cleaning of urban roads and pavements.

Since Dongfeng manufactures a variety of models, the specifications can vary. Here are the common details and technical specifications, often based on a typical medium-to-large capacity model (e.g., 8 to 12 cubic meters total capacity):

Key Functions and Operational Features

• Multi-functional Cleaning: Combines sweeping, high-pressure water washing, and vacuuming for dust and debris removal.
• Sweeping Mechanism: Typically uses a central four-disc sweep system with a rear-mounted suction nozzle.
• Side Brushes: The brushes concentrate debris into the suction path. They often have an automatic obstacle avoidance function and can be independently controlled.
• Sweeping Width: Usually ranges from 2.5 to 3.5 meters.
• Sweeping Speed (Working Speed): Approximately 3 - 25 km/h.
• Cleaning Efficiency: Often stated as ≥95% or ≥98%.
• Vacuum Suction: Employs a powerful centrifugal fan and suction nozzle to collect debris, including large particles (up to about 110 mm in diameter).
• Dust Suppression & Washing:
  • Low-Pressure Spray: Water spray nozzles are positioned above the side brushes to suppress dust during sweeping, preventing secondary pollution.
  • High-Pressure Washing: Features a fan-shaped high-pressure spray bar, sometimes referred to as a "U-shaped water knife," to dislodge stubborn attachments and wash the pavement, curbs, and curb faces.
  • Manual High-Pressure Lance: Often includes an automatic winding reel with a high-pressure lance for manual cleaning of the truck itself or other objects.

1. With auxiliary engine. It is with JMC 64KW vice engine and supply enough power for the suction devices. The vice engine is connected to the fan adopts automatic centrifugal clutch, can guarantee the vice engine no-load start.
