The DX420LC-3 excavator has been upgraded with improved engine horsepower, lift capacity and cooling capabilities, according to Doosan. With an operating weight of 92,374 lbs., a maximum digging depth of 25 ft., 5 in., a dump height of 25 ft., 4 in. and maximum digging reach of 37 ft., the DX420LC-3 is capable of handling a variety of applications. A six-cylinder, 362-hp, water-cooled diesel engine powers the excavator. Doosan says the engine has been optimized for use with a cooled exhaust gas recirculation system, a diesel oxidation catalyst and a diesel particulate filter. The turbocharged engine features a high-pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder.
