Doosan has launched the company’s first Stage V medium size crawler excavator, the new DX300LC-7. This new 30t model offers a combination of performance, operating features, fuel efficiency, reliability and durability.

The new DX300LC-7 Stage V excavator builds on the design of the previous Stage IV machine. It introduces enhancements in operator comfort, machine controllability, productivity, uptime and return on investment, with a focus on low fuel consumption, increased power, robustness and versatility.  Key new features include a new touch enabled colour LCD gauge panel, providing more information via a larger screen, a stereo system integrated in the gauge panel, smart keyless start system (optional), improved interior cab design, and a variety of optional extras. As standard, 360° cameras provide full visibility around the excavator. The camera array comprises of a front camera, two side cameras and a rear camera. 

To meet Stage V engine emission regulations, the new DX300LC-7 excavator is powered by the latest generation Doosan DL08 diesel engine, providing 202kW of power at 1,800 RPM.  The DL08 engine offers a new solution to exceed Stage V regulations without exhaust gas recirculation, with this being combined with after treatment technology to ensure minimal emissions. Thanks to the new technology, maintenance of the diesel particulate filter has been reduced, with no maintenance required until the machine has operated for 8,000h.

With the DX300LC-7, Doosan has attempted to ensure that productivity and environmental protection are compatible. The enhanced fuel efficiency of the engine in combination with a new hydraulic main valve and the new generation SPC3 smart power controls, provides increased fuel saving in the ‘S’ mode and ‘P+’ modes when compared to the previous generation machine. These features are two in a range of four power modes now available on the DX300LC-7, which help to simplify the operation of the new excavator. The operator is able to set the power mode (P+, P, S or E) in both one way and two way working modes.

The new DX300LC-7 model is factory installed with DoosanConnect wireless fleet monitoring system, which offers a web based fleet management solution for monitoring the performance and security of machines and promoting preventative maintenance. It is available as a standard feature on all new Doosan excavators (from 14t), all new Doosan wheel loaders and Doosan ADTs.
