Doosan adds power to its 22-tonner

8 May 13 Doosan says that its new 22-tonne excavator is 13% more productive that the predecessor model and uses 18% less fuel.

The Stage IIIB-compliant DX225LC-3 is claimed to be faster and stronger than before, with an 8% improvement in traction force

The manufacturer says: “The DX225LC-3 excavator provides an optimum balance between displacement and engine power.”

It is powered by a six-cylinder, turbocharged Doosan DL06K water-cooled diesel engine with cooled exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) after-treatment technologies to meet the emission standard.

With a high-pressure common-rail design with direct fuel injection and electronic control, the engine has a power output of 124kW (167hp) at 1800 rpm.

Operating weight is 21.9 tonnes with the standard boom and arm and a 0.92m3 bucket.  Bucket breakout force is 15.2 tonnes (ISO), while the arm breakout force is 10.8 tonnes (ISO).  In the standard monobloc configuration, the maximum digging depth is 6.58m and maximum digging reach is 9.8m at ground level.  The latter figure rises to 10.1m in the articulated configuration and to 15.3m with super long-reach front equipment installed.
