Doosan Infracore Europe has launched the company’s next generation mini-excavator range, the DX50Z-7 5.4 tonne and the DX55R-7 5.7 tonne.
Both models are powered by the Doosan D18 Stage V compliant diesel engine, providing 36.4 kW (48.8 HP) of power at 2200rpm. As a result, the new range offers high power and torque, to cover a range of applications including heavy duty work, while the zero-tail swing and reduced radius design of the DX50Z-7 and DX55R-7, respectively, is ideal for work in confined spaces on construction, landscaping and utility projects.
These machines also offer a high auxiliary flow of 80 l/min to enhance work with attachments. Newly designed cast counterweights ensure excellent machine balance and stability when working. An additional 200 kg bolt-mounted counterweight option is available for the DX55R-7.
The mini excavators’ cab also hosts new key features: an enhanced heating and air conditioning (HVAC) system, DAB audio, eight-inch touch screen, air suspension seat with heating, thumbwheel joystick, A/C control panel keypad, dozer lever, a full glass entry door and high luminance LED work lamps.
The dozer control provides a new blade floating function – pushing the dozer lever all the way forward puts the lever into the detent position and leaves the dozer blade in a ‘float’ position. Customers can also choose the optional dozer lock function, which prevents dozer blade creep.
