The Dolica road sweeper is an urban road sweeping vehicle modified from the Dongfeng Dolica series light or medium-duty chassis.Its primary functions include dry and wet sweeping,dust removal,and garbage collection on urban roads.It is an indispensable auxiliary equipment for urban sanitation,road maintenance,industrial and mining parks,and other areas.
▲Structural Composition and Main Components
The Dolica road sweeper generally consists of the following main components:
Chassis
It utilizes a Dongfeng Dolica series chassis(such as the D6,D7,and D9)with appropriate load capacity,axles,transmission,and suspension system.The chassis provides basic functions such as power,driving support,steering,and braking.
Sweeping System(Top Mounted)
Includes the main brush,side brushes,dust suction blower,suction port,dust box,water pump,and spray system.
Main and Side Brushes:The main brush is located in the center of the vehicle's underbody,focusing on cleaning the center of the road.Side brushes are mounted on both sides of the vehicle to sweep roadside debris into the area covered by the main brush.Dust collection fan:Typically a high-flow centrifugal fan,it uses wind power to draw swept dust and debris into the dust bin.
Dust bin(trash bin):Temporarily stores collected trash and dust for removal or disposal.
Spraying system:In dry or dusty environments,it sprays water to reduce dust and prevent it from being raised during the sweeping process.
Water supply and spray system:Provides water for the spraying system to clean the road surface and moisten dust.It typically includes a water tank,water pump,piping,and nozzles.
Control system and operator interface:The operator has an operating console in the cab,which controls the main and side brush speeds,fan suction,water pump spray,lift control,sweeping speed,and more.Modern models may feature electro-hydraulic control,LCD display,automated,or remote monitoring capabilities.
▲Operating Principle
Doleka road sweepers typically operate using a combination of"suction+sweeping+washing":
The side brush sweeps roadside dust and debris into the main brush area;
The main brush concentrates and pushes debris toward the center;
The dust extraction fan generates airflow through the suction port,sucking these particles directly into the dust bin;
Simultaneously,the spray system sprays water onto the working surface to suppress dust;
The road surface can also be"flushed"during operation depending on the environment.
The entire process ensures road cleanliness while minimizing secondary dust.
▲Application Scenarios
Doleka road sweepers are suitable for the following main scenarios:
Urban road cleaning:Main and secondary urban roads,sidewalks,and ring roads;
Industrial parks/factories:Daily cleaning of internal factory roads and logistics corridors;
Residential communities/commercial plazas:Ground environment maintenance;
Municipal engineering/construction site roads:Dust removal on construction side roads and temporary roads;
Emergency cleaning:Emergency response(such as sandstorms,road sanding,and emergency pollution).
▲Advantages and Challenges
Advantages
Efficient Cleaning:The combined cleaning method of side brushes,main brushes,and dust collection quickly removes road debris and dust.
Excellent Dust Suppression:The water spray system effectively controls dust,enhancing cleaning performance.
Adaptability:The system can adapt to various road conditions and dust levels,offering high flexibility.
Environmental Protection:Modern models can adopt national emission standards or new energy upgrades to reduce pollution emissions.
Challenges and Considerations
Maintenance Cost:Components such as the brushes,dust collection blower,and spray system require regular maintenance and replacement.
Failure Risk:Components wear rapidly in complex road conditions and heavy dust;suction of large debris may cause blockage.
Water Source Dependence:The spray system requires a water source;insufficient water will hinder dust suppression.
Adaptability Issues:Operation efficiency may decrease in extreme weather conditions(such as cold winters,hot and dry weather).
Cost Investment:High-end configurations or intelligent upgrades are costly.Summary and Outlook
Overall,the Dolica road sweeper,with its mature chassis platform,comprehensive sweeping system,and excellent cost-effectiveness,has become a popular choice for urban sanitation and road cleaning in China.With the strengthening of environmental regulations and the advancement of smart sanitation systems,Dolica road sweepers are expected to continue to upgrade in the future with features such as new energy drive,remote monitoring,automated dispatching,and energy conservation and emission reduction,becoming a key component of cities'"clean image."

▲FAQ

Q. How do new energy garbage trucks work?
A. New energy garbage trucks operate similarly to traditional garbage trucks, using the vehicle's powertrain to drive the garbage bins for loading, unloading, and transporting garbage. However, new energy garbage trucks primarily rely on non-traditional power sources such as batteries, electric drive systems, or natural gas engines, reducing fuel consumption and exhaust emissions.

Q. What are the advantages over traditional fuel-powered road sweepers?
A. Zero emissions:No exhaust pollution,complying with national environmental protection policies.
Low noise:Suitable for nighttime operations or in crowded areas.
Low operating costs:Electricity costs are lower than fuel costs,resulting in lower maintenance costs.
High intelligence:Some new energy vehicles support features such as autonomous driving and intelligent dispatching.

Q. What's the difference between new energy road sweepers and traditional road sweepers?
A. The primary difference between new energy road sweepers lies in their power source.Traditional road sweepers typically use diesel or gasoline engines,while new energy vehicles utilize electric or hybrid systems.New energy vehicles offer the following benefits:
Lower emissions,meeting environmental standards;
Quieter operation,reducing noise pollution;
Energy efficiency,reducing fuel consumption.
