Doosan Construction Equipment has launched a Dash-3 version of its popular reduced-radius 15tonne excavator, the DX140LCR-3. Powered by a Cummins QSB4.5 Stage IIIB-compliant engine, with exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), the machine has 10% more power and 15% more torque than the previous model. Both main boom and dipper arm forces get an 8% boost, while travel speeds are increased to 5.3km/h, resulting in a claimed a 10% increase in productivity.
