Doosan has launched the new DX800LC-7 Stage V compliant 80 tonne crawler excavator, the largest excavator model ever manufactured by the company. Coinciding with the launch, Doosan has announced the sale of the first DX800LC-7 in Europe to a customer in Finland.

The DX800LC-7 excavator is powered by the new stage V version of the well-proven Perkins 2506J diesel engine, providing a high power output of 403 kW (548 HP), more than any other machine in this class. The engine meets Stage V emission regulations by utilising exhaust gas recirculation, selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies.

The DPF automatically regenerates every 25 hours and the excavator continues to work unaffected during this regeneration phase. The operator can check the status of the DPF via the display on the gauge panel in the cab.
