Doosan’s new excavator offers increased performance
Bucket, arm and swing forces in the DX300LC-5 remain the same as the Stage IIIB model, but the drawbar pull has been sharply increased by 8%. The operating weight of the DX300LC-5 has increased 900kg, resulting in a lifting capacity increase of 1% over the front and 5% over the side.
The new machine’s styling allows increased driver comfort and vehicular controllability with new features to boost fuel efficiency, uptime and return on investment.
The new DX300LC-5 is powered by a
The engine also meets Stage IV emissions regulations without needing a diesel particulate filter (DPF). The unit has cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.
To help meet Stage IV regulations, Doosan added a mass airflow sensor and exhaust brake to the engine. The sensor allows the electronic control unit to optimise airflow provided by the variable geometry turbocharger. It also optimises fuel delivery to the combustion chamber based on air intake volume and rpm.
Other exclusive features of the Scania engines are the dual fuel filter and water separator systems. A full-flow paper fuel filter removes large particles with a centrifugal cleaner filtering out small particles, providing operating economy and lower environmental impact.
The water separator has a 10 micron primary filter connected directly to the fuel tank and a 3 micron pressure-type secondary filter. Both filters are equipped with a heating function as standard for better cold crank performance.
New for this model is a trip meter setting screen which allows operators to check fuel consumption daily or over a set period directly from the control panel.
