Doosan has extended its new-generation mini excavator range with the launch of the 2t class DX20Z-7 model.
“Providing a unique combination of high performance and compactness, the new DX20Z-7 is 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 company said.
“The DX20Z-7 ensures increased productivity, excellent operator comfort in an easily accessed operator station and maximum durability and serviceability.”
The optimised hydraulic system in the DX20Z-7 mini excavator is designed to make the best possible use of the engine power available from the Yanmar 3TNV70 3-cylinder Stage V diesel engine providing an output of 10.3 kW (13.8 HP)at 2,200 RPM.
“These result in fast cycle times combined with smooth control of breakout forces, which include a digging force over the bucket (ISO) of 1.55t,” said Doosan.
In its standard configuration, the DX20Z-7 has an operating weight of 1,995 kg. 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 maximum performance and versatility in operating a wide range of attachments,” said Doosan.
“The high lifting capacity and superior dumping height offered by the DX20Z-7 ensure that loading trucks is an easy process, while the reach at ground level reduces the need to keep repositioning when digging,” it added.
“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 for the excavator, especially when working over the side. Expansion and retraction are simple and easy via as witch on the control panel.”
The company emphasised that 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,” it stated.
