Doosan has launched its first Stage V medium-sized crawler excavator: the new DX300LC-7 30 t model. This new ‘-7’ model combines high performance, operating features, fuel efficiency, reliability, and durability.
The 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. There is also a strong focus on fuel consumption, increased power, robustness, and versatility.
Spacious and ergonomic, the new cab offers improved operator comfort and ease of operation. As well as a high-quality seat, the cab also offers more features as standard than other machines on the market, ensuring controllability and high precision in applications.
New features in the cab include an 8 in. touch-enabled LCD gauge panel, providing more information via a 30% larger screen; a stereo system integrated in the gauge panel; the option for a smart keyless start system; improved interior cab design; the option for ultrasonic sonic detection of obstacles; the option for LED lights; the option for side protection; and the option for an air compressor.
As standard, 360° cameras provide full visibility around the excavator and allow the operator to see a top-down view of the area outside the machine. The camera array comprises a front camera, two side cameras, and a rear camera. The camera display is separated from the gauge panel.
To meet Stage V engine emission regulations, the new excavator is powered by the latest generation Doosan DL08 diesel engine, providing 202 kW power at 1800 RPM. The engine offers a new solution to exceed Stage V regulations without exhaust gas recirculation, which boosts the quantity of air available during combustion, increasing the temperature of the process and greatly reducing the amount of particulates produced. This is combined with efficient DOC/DPF+SCR after-treatment technology, to ensure minimal emissions.
As a result of new technology, maintenance of the diesel particulate filter has been greatly reduced, with no maintenance required until the machine has operated for 8000 hours.
With the DX300LC-7, Doosan has tried 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 Control, provides increased fuel saving (+7% in the S mode and +6% in the P+ mode) compared to the previous generation machine.
S and P+ are two in the range of power modes now available on the machine, which help to simplify the operation of the new excavator compared to the more complex choice of eight power modes and SPC combinations in the previous generation machine. 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 model is factory installed with a DoosanConnect wireless fleet monitoring system, which offers a web-based fleet management solution that is useful for monitoring the performance and security of machines, as well as promoting preventative maintenance. It is available as a standard feature on all new Doosan excavators (from 14 t), wheel loaders, and ADTs.
