Doosan Launches New DL420-7 Stage V Wheel Loader

Higher productivity
The Doosan DL420-7 has a larger standard bucket capacity of 4.5 m3, the largest in its class. The wheel loader also delivers a productivity increase of 7% over the previous '-5' model. 5-speed automatic powershift transmission and heavy-duty HDL axles as standard ensure that the Doosan DL420-7 performs exceptionally, especially in high-load environments. The Doosan DL420-7 also features smooth and responsive hydraulics and auxiliary hydraulics, to provide the ideal material handling solution in construction, demolition, waste, recycling, mining and quarrying.

The Doosan DL420-7 is powered by the new Scania DC13 Stage V 6-cylinder engine. It has an output of 257 kW (345 hp) at 1800 rpm and an impressive peak torque of 2196 Nm at 1100 rpm. The new engine meets Stage V emissions regulations, without the need for exhaust gas recirculation (EGR). This through Selective Catalyst Reduction, Diesel Oxidation Catalyst and Diesel Particulate Filter (DPF) aftertreatment technologies. The ash cleaning cycle on the DPF has been improved to over 6000 hours and the operator is fully aware of the status of the DPF via a soot level indicator on the new 8” in-cab touchscreen.

Increased fuel efficiency
The Stage V engine delivers 5% fuel savings without the need for EGR. The new generation energy management system Situation Awareness Technology (SAT2) automatically scans machine activity and adjusts engine power according to 'real-time' analysis of boom pressure, pump pressure and output shaft.

New, spacious and ergonomic cab design
Using the new Doosan Smart Key system on the in-cab control panel, the operator can start the machine with a 'keyless' device. This helps prevent theft of the machine. 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 unlock, search and other functions. The control panel also contains two USB connections.

The new EMCV (Electric Main Control Valve) joystick is fully integrated into the armrest and one of the standard features in the cab. The EMCV joystick provides the operator with smoother and more accurate wheel loader control. Joystick control sensitivity can be set and changed according to operator preferences, using the new 8-inch touchscreen monitor.

330/5000
The touchscreen display offers an innovative all-in-one design:
- New graphics;
- Fully adjustable positioning;
- Simple menu navigation including 'quick menu' function;
- Machine settings and information;
- Performance information;
- Optional weighing system;
- Rear view camera;
- HVAC and A/C controls;
- 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. In addition, the cab features a 3-point seat belt with alarm icons on the touchscreen monitor and on the gauge panel with a new layout and anti-reflective glass.

Excellent operator visibility
The new cab provides the operator with a vastly improved field of vision, with minimal blind spots around the cab and a 14% larger glass window area compared to the previous Doosan DL420-5 model . Doosan The DL420-7 also offers electrically adjustable rear-view mirrors for added safety. Full LED work lights are installed on the cab (four at the front and rear as standard, with the option of six at the front and rear). The LED lights on the rear hood have an automatic strobe function to indicate when the wheel loader is backing up.

An air compressor with air blower is also available as an option: mounted in the cab for easy access. This is a powerful tool for cleaning the cabin when needed.

To 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 Doosan DL420-7. The new wheel loader can also be ordered with a choice of different counterweights. Options are 300, 400 or 500 kg, depending on the application.

DoosanCONNECT Fleet Monitoring System
The Doosan DL420-7 is factory installed with the latest DoosanCONNECT TMS2.0 state of the art wireless fleet monitoring system. The DoosanCONNECT system is a tool specially designed for the Doosan range and provides comprehensive information on machine performance in a dual mode (satellite, mobile network).

The DoosanCONNECT system provides an online fleet and asset management solution, which is very useful for managing the performance and security of machines and for promoting preventive maintenance.
