DOOSAN has added the new DL420-7 Stage V wheel loader to its portfolio, boasting a new design, increased fuel efficiency and a more comfortable operating environment.
The machine has a standard bucket capacity of 4.5 m3 and provides a 7% increase in productivity over the previous ‘-5’ model, according to the manufacturer. With automatic 5-speed powershift transmission and heavy duty HDL axles as standard, the DL420-7 is said to excel in high-load environments.
The model is powered by the new Scania DC13 Stage V 6-cylinder engine, producing 257 kW (345 HP) of power at 1800 rpm. The new engine meets Stage V 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.
With no EGR needed and a new selection of power modes available, Doosan revealed the engine provides a 5% reduction in fuel consumption. The new generation Situation Awareness Technology (SAT2) power management system automatically scans the machine’s activity and adjusts engine output according to real time analysis of the boom pressure, pump pressure and output shaft.
Using the new Doosan Smart Key system in the cab’s control panel, 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 functions such as remote door control, door lock and unlock, and door release.
The new EMCV (Electric Main Control Valve) joystick is fully integrated in the armrest, which Doosan said provides ‘smoother and precise’ controllability. The sensitivity of the joystick control can be altered according to preference using the new eight inch touchscreen monitor.
The cab features a Grammer Actimo XXL seat with adjustable horizontal and vertical suspension settings, a pneumatic lumbar function and seat heating as standard. There is a 3-point safety belt with alarm icons on the monitor and on the gauge panel.
There is 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. Full LED working lights are installed. An air compressor with air blower is available as an option.
The machine is factory-installed with the latest DoosanCONNECT TMS2.0 wireless fleet monitoring system.
