New Doosan wheel loader
Doosan Infracore Europe has launched the new DL420-7 Stage 5 wheel loader, featuring a completely new design, providing higher performance, increased fuel efficiency and an improved environment for the operator compared to the previous Stage 4 model.
The DL420-7 introduces a fresh look for the Doosan wheel loader range, with a brand new spacious, ergonomic cab and innovative features for higher productivity, increased controllability and operator comfort. As with all Doosan wheel loaders, most of these features are standard on the DL420-7, unlike other machines on the market where they are options.
With an operating weight of 23,990kg, the DL420-7 has a higher standard bucket capacity of 4.5m3 and provides a 7% increase in productivity over the previous ‘-5’ model. Maximum breakout force is 171kN. The new model boasts an automatic five-speed powershift transmission and heavy duty HDL axles as standard, too. The DL420-7 is powered by the new Scania DC13 Stage 5 six-cylinder engine producing 345hp of power at 1,800rpm and providing an impressive maximum torque of 2196Nm at 1,100 rpm. Compared with the old motor, Doosan reckons the new engine reduces fuel consumption by 5%.
The new engine meets Stage 5 emission regulations without the need for exhaust gas recirculation (EGR), through the use of selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies. The ash cleaning cycle on the DPF has been improved to over 6,000 hours and the operator is fully informed about the status of the DPF via a soot level indicator on the new eight-inch touch screen display in the cab.
Using the new Doosan Smart Key system on the control panel in the cab, the operator can start the machine using a keyless device, helping to prevent machine theft. Up to six machines can be registered on each keyless device and the Smart Key system provides remote door control, door lock and unlock, door release, searching and other functions. The control panel also includes two USB sockets.
The new EMCV (Electric Main Control Valve) joystick fully integrated in the armrest is another standard feature in the cab, providing the operator with smoother and precise controllability of the wheel loader. The sensitivity of the joystick control can be set and altered according to operator preferences using the new eight-inch touch screen monitor.
The new cab offers a greatly improved field of vision for the operator, with blind spots around the cab minimised and a 14% larger glass window area compared to the previous DL420-5 model. The DL420-7 also offers the option of electrically adjustable rear view mirrors for added safety. Full LED working lights are installed on the cab (four on both the front and rear as standard, with the option of six at the front and rear). The LED lights on the rear bonnet have an automatic strobe function to indicate when the wheel loader is reversing.
The DL420-7 is factory-installed with the latest DoosanCONNECT TMS2.0 state-of-art wireless fleet monitoring system. The DoosanCONNECT system is a tool designed specifically for the Doosan range, providing comprehensive information about machine performance in a dual mode (satellite, Mobile network).
