First Doosan DL420-7 wheel loaders in Germany
Ottenbüttler Sand Gesellschaft mbH of Dammfleth has taken delivery of the first two Doosan DL420-7 wheel loaders in Germany. The two new DL420-7s are currently in use in the company’s sand pits at Ottenbühl and Peissen, where they are used to extract fill sand and process it into different grain size groups by dry screening.
The two wheel loaders are in operation in the sand pits for around ten hours a day. Their main tasks involve removal of material direct from the walls of the pits, feeding the screening plant and then loading the graded sand onto the trucks. The machines are also used in construction waste recycling.
The DL420-7 is powered by the new Scania DC13 6-cylinder engine producing 345hp of power at 1,800rpm and providing an impressive maximum torque of 2,196Nm at 1,100rpm. The new engine meets Stage 5 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 6,000 hours 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.
A major feature of Doosan DL-7 wheel loaders is the completely redesigned cab. The latter offers greatly improved visibility, the use of touchscreen displays and much more space for the driver. In addition, 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 wheel loaders at Ottenbüttler Sand are also equipped with a full light package and a compressor for cleaning the cab.
