Type: Usually a Vacuum Road Sweeper or a combined Sweep and Suck Type. Some models also incorporate a High-Pressure Washing/Sprinkler function for dust suppression and removing stubborn stains, making them multi-functional.

Chassis: Often built on a reliable Dongfeng truck chassis for the larger models.

Cleaning Mechanism: Typically uses a system of sweeper brushes (side brushes and main brush) to collect debris and a powerful vacuum suction device to lift the material into the garbage tank.

Power: Larger models use a main engine (Chassis engine) for driving and an auxiliary engine (often Cummins or similar) to power the sweeping and vacuum system. Mini-sweepers are often pure electric (battery-powered) for zero emissions and low noise.

Tanks: Equipped with a Dust/Garbage Tank (Hopper) and a Water Tank for dust suppression. Volumes vary widely (e.g., mini-sweepers might have a 150L dustbin, while truck models can have 3-8 m 3 dust tanks).

Operation: Modern models often feature a hydraulic system in the cab for controlling the brushes, suction nozzle, and tank dumping, sometimes with one-button operation.

Efficiency: Designed for high cleaning efficiency, often ≥95%.

Road sweeper truck is a new type of high efficient cleaning equipment which integrates road cleaning, garbage collection and transportation. it is widely used in city streets, road, station, square etc. Road sweeper 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 boxes and water tank produced by our company are made of stainless steel,the inside of the garbage box has filter nets, which can effectively prevent the leaves,plastic bags or other light objects to clog the tuyere. Water tank inside is anticorrosion, antirust and antitoxic. Road sweeper truck is equipped with 4 brushes, both sides of the brushes can be working together, or unilateral work independently. The operating system of road sweeping truck, rear dust absorption plate absorb the rubbish on the ground. The height can be adjust according to requirement.Road sweeper truck have an auxiliary engine which can offer power for fan and hydraulic oil pump. Fan supply suction power for the suction system, hydraulic oil pump complete the lift of van box and switching of rear door. The nozzle is installed at cleaning brushes and the rear and front of the truck to drop dust by spraying water. The control box is in the cab, all kinds of system electrical centralized to control, and easy to operate.

1. Imported high quality hydraulic motor.
2. Stainless steel garbage box with anticorrosion.
3. The cleaning brushes can avoid automatically and adjust the speed.
4. Both sides of the brushes can be working together, or unilateral work independently.

Sweeping Mechanism: Often features a central installation of 4 sweeping discs (brushes) or a similar configuration, with the right or left front brush often having independent control and an anti-collision avoidance function.

Vacuum System: Uses a powerful centrifugal fan to create high-speed airflow for efficient vacuuming, often with a large suction entrance diameter (e.g., 200mm).

Dust Suppression: Includes a spraying water system with an electric diaphragm pump, water filter, and nozzles, to wet the ground and suppress dust during sweeping.

Discharge: The garbage tank typically uses a hydraulic system to tilt and discharge collected waste (Discharge Angle ≥45 ∘ ).

Controls: Operations for the sweeping system (brushes, suction, tilting) are typically controlled by an electrical control system from the cabin.

These "mini" or small-to-medium-capacity Dongfeng road sweepers are primarily designed for cleaning tasks in:

• Urban streets and city roads.
• Narrow lanes, alleys, and residential areas (where maneuverability is key).
• Municipal squares and parks.
• Industrial areas and factory grounds.

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!

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.
2. Vacuum device and suction nozzle arrangement adopts "wide of suction nozzle by the main suction + left and right side suction nozzle structure arrangement. The suction cup device has the function of avoiding and resetting automatically when encountering obstacles.This function can effectively solve the problem of easily damaged dust collector. Full floating suction nozzle, with the characteristics of large vacuum width, high vacuum efficiency, and conducive to the adjustment and maintenance of suction nozzle.
3. The liner of dustbin adopts double structure, the inner layer is all stainless steel;The high efficiency filtration of 4 sets of polymer filter cylinders can effectively reduce the secondary pollution caused by dust.
4. The front part of the truck is equipped with an automatic emergency system of hand pump.The tail is equipped with an optional water spray dust removal device;Open and close the garbage box door and garbage dump can be operated in the driving room, which is safe, convenient and reliable.
5. The filter cylinder of the vacuum truck can effectively separate the dust absorbed by the vacuum truck so as to avoid secondary dust pollution. There are two cleaning methods for the filter cylinder of the vacuum truck, one is equipped with automatic pulsed dust cleaning, and the other is disassembled and cleaning. Both are easy to operate.
