Doosan has extended its mini-excavator family, with the launch of the new two tonne DX20Z-7 micro excavator.
Providing a combination of high performance and compactness, the DX20Z-7 is a boon in confined space and indoor job sites, offering a zero tail swing and a detachable canopy for low height entrance.
The optimised hydraulic system in the DX20Z-7 takes advantage of the Yanmar 3TNV70 three-cylinder Stage V desel engine, providing an output of 10.3 kWat 2200rpm. This results in fast cycle times combined with smooth control of breakout forces, which include a digging force over the bucket of 1.55 tonnes.
In its standard configuration, the DX20Z-7 has an operating weight of 1995kg. With the optional 1.1m arm, the maximum digging depth is 2345 mm, 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 optimum stability, especially when working to the side.
The DX20Z-7 is built around the operator, with ample space for the feet, a flat floor for easy cleaning, ergonomic pedals and easy access to all controls. Visibility to the front is optimised by a high luminescent LED lamp on the boom.
The use of durable materials ensures that the DX20Z-7 offers hard-wearing and robust performance. All components and features are tested under extreme conditions, and the heavy gauge steel tailgate can be quickly opened, allowing immediate access to components such as coolers and other daily maintenance and service points.
