Mini-excavator launch marks a Doosan double

DOOSAN has launched the first of the company’s next generation mini-excavator range with new shared global styling.

The DX50Z-7 5.4-tonne and DX55R-7 5.7-tonne Stage V-compliant models are described as ‘ideal’ for work in confined spaces thanks to the zero tail swing and reduced radius design of the models, respectively.

Both machines are powered by the Doosan D18 diesel engine providing 36.4 kW (48.8 HP) of power at 2200 RPM.

The manufacturer explained that a ‘novel’ platform design featuring new upper structures has increased durability/robustness, which is complemented by a larger working range than other equivalent machines on the market, coupled with higher lifting capacities and digging forces.

The mini-diggers offer a high auxiliary flow of 80 l/min to enhance work with attachments. Newly designed cast counterweights are said to ensure ‘excellent’ machine balance and stability, while an additional 200 kg bolt-mounted counterweight option is available for the DX55R-7.

The new cab has a full glass entry door to maximise visibility. The high luminance LED work lamps further enhance visibility and additional LED lamps are available as an option.

Key features of the new cab include: an enhanced heating and air conditioning (HVAC) system; DAB audio; sunglasses case; eight inch touchscreen; air suspension seat with heating; thumbwheel joystick; A/C control panel keypad; USB charger & 12V socket; foldable pedals; and dozer control.

The DX50Z-7 and DX55R-7 machines contain Doosan’s latest telematics management system DoosanCONNECT installed as standard.
