Sdlg 22t-RS8220 heavy-duty self-propelled vibratory roller for high-grade highways
The RS8220 mechanical single-drum vibratory roller is a heavy-duty self-propelled vibratory roller, which can effectively compact various soil layers and rock fills. The machine is at the leading level in the industry in terms of compaction performance, driving performance, handling performance, reliability, maintenance and repair performance. This machine is an ideal compaction equipment for high-grade highways, airports, ports, railways, dams and industrial sites.
1. It adopts Weichai's electronically controlled high-pressure common rail engine that meets the national III emission standards, with multi-stage fuel injection, high combustion efficiency, torque increase by 12%, and strong power.
2. Equipped with Lingong's new reinforced drive axle, with strong bearing capacity and high reliability.
3. The synchronizer gearbox is adopted, with three gears in the front and two in the rear. It has the functions of neutral start and reverse gear warning, smooth shifting, light and comfortable operation.
4. The front and rear frames are hinged with slewing support, which is convenient for disassembly and assembly, maintenance-free, and reliable performance.
5. Adopting the excitation mechanism, the amplitude consistency on both sides of the vibrating wheel is high, and the compaction effect is good; the international well-known brand vibrating bearing is adopted, which has large carrying capacity, stability and reliability.
6. It adopts a fully enclosed cab newly optimized and designed according to ergonomics, which is spacious and bright, has a wide view, good sealing effect, and comfortable driving environment.
7. The electrical system of the whole machine adopts centralized control, which is convenient for inspection and maintenance; it adopts step-by-step combined instrument panel, which has high human-computer interaction and can monitor the running status of the whole machine at any time.
8. It adopts electronically controlled linear actuator device, which can be opened with one button, with large opening angle, reasonable layout of maintenance parts, and convenient maintenance.
9. Engineering tires and bump wheels are optional to meet the diverse needs of customers.
