| 摘要： | The optimised hydraulic system in the DX20Z-7 is powered by the Yanmar 3TNV70 three-cylinder Stage Ⅴ diesel, which provides 10.3kW.This results in fast cycle times combined with smooth control of breakout forces. In its standard configuration, the DX20Z-7 has an operating weight of 1.995kg. With the optional 1.1m long arm, the maximum digging depth of the DX20Z-7 is 2345mm, the maximum dump height is 2750mm and the maximum reach at ground level is 3975mm. When at its fully retracted width of 950mm, the retractable undercarriage on the DX20Z-7 allows the machine to go through narrow spaces. When fully expanded to a width of 1360mm, it provides stability, especially when working over the side. The use of highly durable materials ensures that the Doosan DX20Z-7 model offers hard-wearing and robust performance. All components and design features are tested under extreme conditions and the heavy steel gauge tailgate ensures extra durability and peace of mind while working. The cylinder guards and battery cover provide extra protection. The tailgate can be opened to provide access for daily maintenance and service points, reducing downtime to a minimum. |
