Said to provide a unique combination of high performance and compactness, the new DX20Z-7 is designed to be an ideal solution for confined space and indoor job sites, offering a zero tail swing design and a detachable canopy for low height entrance. The DX20Z-7 has been developed to provide increased productivity, excellent operator comfort in an easily accessed operator.

Increased productivity

The optimised hydraulic system in the DX20Z-7 mini excavator has been developed to make the best possible use of the engine power available from the Yanmar 3TNV70 three cylinder Stage V diesel engine providing an output of 10.3kW at 2,200rpm. This results in fast cycle times combined with smooth control of breakout forces, which include a digging force over the bucket (ISO) of 1.55t. 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 2,345mm, the maximum dump height is 2,750mm and the maximum reach at ground level is 3,975mm. This working range provides performance and versatility in operating a wide range of attachments.

The high lifting capacity and dumping height offered by the DX20Z-7 ensure that loading a trucks is an easy process, while the reach at ground level reduces the need to keep repositioning when digging.  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 1,360mm, it provides stability for the excavator, especially when working over the side. Expansion and retraction are simple and easy via a switch on the control panel.

Comfort and robust performance

The DX20Z-7 is built around the operator and provides optimal ergonomics. There is ample space for the feet with a flat floor for easy cleaning, ergonomic pedals and easy access to all controls. Visibility to the front is optimised by the high luminescent LED lamp on the boom. 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 quickly opened to provide immediate access to conveniently located components such as easily cleaned coolers and other daily maintenance and service points thereby reducing downtime.
