G9220 is a high-speed, high-efficiency, high-precision and multi-purpose product developed by SDLG on the basis of absorbing European advanced technology. It can achieve ground leveling and trenching, slope scraping, earth moving, snow removal, loosening, compaction, and cloth distribution. , Mixing and other work, widely used in highways, airports, defense engineering, mining construction, road construction, water conservancy construction and farmland improvement and other construction conditions.
1. Equipped with Dalian Deutz electronically controlled single-pump engine that meets the national III emission standard. The Deutz engine platform is adopted, which has high fuel injection pressure, energy saving and environmental protection, and has strong oil adaptability, suitable for harsh working conditions. Three power curves, perfectly matched with ZF gearbox, can choose the corresponding power mode according to the load, to achieve better performance and fuel efficiency, energy saving and high efficiency.
2. The electrical equipment of the whole machine adopts centralized control, three-level alarm electronic monitoring system, digital step-type instrument display, high human-machine interaction, convenient detection and maintenance; the whole machine control has an automatic cruise function, so that the engine works at the set speed. Reduce operator labor intensity.
3. The double-cylinder drive tray-type working device adopting European advanced technology adopts double-rotary oil cylinder and rotary valve structure, which has large driving force and can rotate under load.
4. The swing frame adopts lubrication-free and maintenance-free composite bearings, with small friction coefficient, impact resistance, wear resistance and high reliability; it is positioned by hydraulic locking cylinder, which is easy to operate.
5. Optimized arrangement of the blade structure and the oil cylinder, the operation flatness is high.
6. Optional accessories such as front bulldozing plate, middle ripper, rear ripper, etc., can meet the diverse needs of customers.
7. Equipped with anti-rollover (FOPS / ROPS) cab, it has good airtightness, safety and reliability; wide field of vision, it is helpful to observe the status of the two ends of the blade when turning, crabbing and leveling work, and the operation accuracy is high.
