The Doosan DX300LC excavator is powered by a 213 hp, 6-cylinder Doosan DL08K water-cooled diesel engine that has been optimized for use with a cooled exhaust gas recirculation (CEGR) system, diesel oxidation catalyst (DOC) and diesel particulate filter (DPF). The engine in this configuration is optimized to reduce nitrogen oxides and after treatment is needed to reduce particulate matter to comply with interim Tier 4 (iT4) emission regulations. Moreover, the new intelligent boom float option allows the boom of the excavator to “float” up or down, allowing the operator to focus more on the task while decreasing the machine workload and increasing efficiency. The operator can choose when to engage intelligent boom float functionality via a switch on the control panel. With an operating weight of 66,782 lb., a maximum digging depth of 24 ft., dump height of 23 ft., 10 in. and maximum digging reach of 35 ft., 2 in., the DX300LC is designed for road building, site development and other construction applications.
