Doosan Infracore Europe has launched the new DL420-7 Stage V wheel loader, featuring a completely new design.
The company said the new unit provided higher performance, increased fuel efficiency and a much enhanced environment for the operator compared to 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,” said Doosan.
“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.”
The DL420-7 has a higher standard bucket capacity of 4.5 m3, claimed to be the largest in its class, and provides a 7% increase in productivity over the previous ‘-5’ model.
“With automatic five-speed powershift transmission and heavy-duty HDL axles as standard, the DL420-7 operates exceptionally, especially in high-load environments,” the company continued. “The DL420-7 also has smooth and responsive hydraulics and auxiliary hydraulic connections, to provide the ideal 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 producing 257 kW (345 HP) of power at 1,800 rpm and providing maximum torque of 2196 Nm at 1100 rpm.
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 over 6000h and the operator is fully informed about the status of the DPF via a soot level indicator on the new 8 inch touch screen 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,” said Doosan. “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.”
The new machine also features a new spacious ergonomic cab design. “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,” said Doosan.
“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, designed to provide 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 8-inch touchscreen monitor,” said Doosan.
The touchscreen display offers an innovative all-in-one design, providing:
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 touch screen monitor and on the gauge panel, which features a new layout and anti-reflective glass.
