Doosan launch DL420-7 Stage V wheel loader
New machine offers higher performance, increased fuel efficiency and enhanced operator environment
DOOSAN Infracore Europe have launched the new DL420-7 Stage V wheel loader, featuring a completely new design and providing higher performance, increased fuel efficiency and a much-enhanced environment for the operator compared with the previous Stage IV 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.
The DL420-7 has a standard bucket capacity of 4.5 cubic metres, the largest in its class, and provides a 7% increase in productivity over the previous ‘dash-5’ model. With automatic five-speed powershift transmission and heavy-duty HDL axles as standard, the DL420-7 operates especially well in high-load environments.
The DL420-7 also has smooth and responsive hydraulics and auxiliary hydraulic connections, making it well suited as a material-handling solution for construction, demolition, waste, recycling, mining and quarrying.
The DL420-7 is powered by the new Scania DC13 Stage V 6-cylinder engine which produces 257kW (345hp) at 1,800 rev/min and provides a maximum torque of 2,196Nm at 1,100 rev/min.
The new engine meets Stage V 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 more than 6,000h and the operator is fully informed about the status of the DPF via a soot level indicator on the new 8in touchscreen display in the cab.
With no EGR needed and a new selection of power modes available – SAT2, Standard or Power – the Stage V 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 the engine’s output according to real-time analysis of the boom pressure, pump pressure and output shaft.
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 8in touch-screen monitor.
The touch-screen display offers an innovative all-in-one design, providing new graphics;
fully adjustable positioning; easy menu navigation, including ‘quick-menu’ function; machine settings and information; performance information; optional weighing system; rear-view camera; HVAC and A/C controls; and Help functions.
The new cab has a Grammer Actimo XXL seat with adjustable horizontal and vertical suspension settings, a pneumatic lumbar function and seat heating as standard. There is a three-point safety belt with alarm icons on the touchscreen monitor and on the gauge panel, which features a new layout and anti-reflective glass.
The new cab offers a greatly improved field of vision for the operator, with blind spots around the cab minimized and a 14% larger glass window area compared with 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.
To help meet machine requirements for the wide range of applications in construction, demolition, waste, recycling, mining and quarrying, an optional Doosan weighing system is available on the DL420-7. The new wheel loader can also be ordered with a choice of different counterweights – 300kg, 400kg or 500 kg – depending on the application.
The DL420-7 is factory-installed with the latest DoosanCONNECT TMS2.0 state-of-art wireless fleet-monitoring system, which offers a web-based solution for managing the performance and security of the machine and promoting preventative maintenance.
