Doosan Launches New DL420CVT-7 Wheel Loader
As part of the company’s award-winning DL-7 series, Doosan has launched the new DL420CVT-7 Stage V compliant wheel loader equipped with a Continuously Variable Transmission (CVT) and offering a maximum bucket capacity of 4.5 m3.
The CVT design combines the benefits of a hydraulic mechanical transmission and a hydrostatic transmission in the same machine, ensuring high loads can be carried at low engine speeds with high dynamics for an optimum wheel loader operating cycle. The DL420CVT-7 therefore provides an increase in machine performance for operators working in digging, loading and lifting applications.
The complete driving range, forwards and in reverse, is controlled by the CVT system. Low engine speeds ensure a high efficiency and the highest driving comfort irrespective of the traction speed. The power splitting continuously variable technology facilitates moving off softly and hydraulically. Furthermore, with the CVT, a fuel saving of up to 15% can be achieved.
With an output of 240 kW (326 HP) of power at 1800 RPM, the Scania DC09 engine in the DL420CVT-7 provides generous torque at low RPM and 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.
