With operating weights of 49,600 and 56,700 pounds, respectively, the new mid-size Doosan DX225LC-3 and DX255LC-3 excavators feature significant design enhancements, including Tier 4 Interim engines with cooling-system improvements, selectable power and work modes, new cab-mounting system, and an optional floating boom.

Both new models are powered by the Doosan DL06K diesel engine, rated at 167 horsepower for the DX225LC-3 and 185 for the DX255LC-3. The new Tier 4 Interim engine uses an electronically controlled, high-pressure, common-rail fuel system and a variable-geometry turbocharger in conjunction with a cooled-exhaust-gas-recirculation system, diesel oxidation catalyst, and diesel particulate filter. A new electronic fan clutch is designed to improve cooling-system efficiency, while reducing fuel consumption and sound levels.
