SDLG E690f 9 ton Small multi-working small excavator for underground mining
E690F is a 9-ton multi-working small excavator. Mainly engaged in the excavation, loading and unloading of materials such as soil, sand, coal, garbage and other materials, crushing, and leveling operations. It is widely used in mines, construction sites, underground mining, gardens, municipal administration and urban construction.
1. The original imported Yanmar 4TNV98T turbocharged engine meets the T3 emission requirements. It has strong power, high reliability, automatic idling function, low emission, low noise and low fuel consumption.
2. Load sensing hydraulic system, pilot control, high efficiency and energy saving, light operation, better coordination of compound actions.
3. It adopts reinforced upper and lower frame, with strong carrying capacity, reasonable load distribution of the whole machine, and good stability. X-type off-frame, high stability of the whole machine; standard enhanced working device, the whole machine has a strong ability to adapt to harsh working conditions.
4. Optimized design of the cab, spacious and bright, wide vision, good sealing effect, high-end shock-absorbing seats, dual-stage filter heating and cooling air-conditioning, silicone oil rubber three-stage shock absorber, good shock absorption effect, comfortable driving environment.
5. The electrical system of the whole machine adopts centralized control, which has high reliability and convenient maintenance and inspection; the intelligent monitoring system can monitor the working status of the whole machine in real time, and has good man-machine interaction.
6. It can realize quick change and a variety of accessory configurations, and try to meet the needs of users with one machine and multiple working conditions.
