Dongfeng Duolika D7 dry road sweeper
Dongfeng Duolika D7 Dry Road Sweeper Truck
The Dongfeng Duolika D7 dry road sweeper is designed for efficient mechanical street cleaning in urban roads, industrial parks, factories, and public areas. Featuring a pure mechanical sweeping and vacuum suction system without a high-pressure washing unit, it offers a simple structure, reliable performance, and lower maintenance costs for daily cleaning operations.
Efficient Mechanical Sweeping System
The vehicle adopts a four-center brush configuration with a rear floating suction nozzle to achieve effective debris collection across a sweeping width of up to 3 meters. The maintenance-free centrifugal fan delivers a maximum air volume of 12,000 m³/h, while the vacuum system efficiently collects sand, leaves, gravel, plastic bags, and other common road debris with a collection efficiency of up to 98%.
Independent Auxiliary Power System
An independent auxiliary diesel engine powers the hydraulic system and vacuum fan, allowing the sweeping equipment to operate at a stable speed regardless of the chassis engine. This design improves sweeping consistency, reduces wear on the main powertrain, and provides dependable performance during long working hours. Customers can also choose an optional Cummins auxiliary engine for more demanding operating conditions.
Durable Structure with Low Maintenance Requirements
The integrated refuse hopper and clean water tank are manufactured from corrosion-resistant SUS304 stainless steel for extended service life. A hydraulic rear tipping hopper simplifies refuse unloading, while the low-pressure water mist system effectively suppresses dust during sweeping without the complexity of a high-pressure washing system, reducing maintenance requirements and operating costs.
Reliable Chassis for Daily Municipal Service
Built on the Dongfeng Duolika D7 sanitation chassis, the sweeper is powered by a 165 HP Euro III diesel engine that operates without an SCR or AdBlue system, making routine maintenance easier in many export markets. The reinforced chassis, six-speed manual transmission, heavy-duty suspension, and ABS braking system provide dependable performance for continuous municipal sanitation work.
Suitable for Various Cleaning Applications
The Dongfeng Duolika D7 dry road sweeper is suitable for municipal streets, industrial facilities, logistics parks, residential communities, airports, ports, and factory roads. Its combination of efficient mechanical sweeping, reliable vacuum collection, straightforward maintenance, and practical operating costs makes it an effective solution for customers seeking dependable daily road cleaning equipment.
