Doosan Infracore Construction Equipment has launched its new Stage IIIB compliant DX300LC-3 crawler excavator.

The company says that its highlights include operator comfort with a special jog/shuttle control; very high performance and fuel efficiency; outstanding drawbar pull and digging forces; enhanced controllability and serviceability, and many other features as standard.

The new ROPS and OPG-certified cab offers 6% more space for the operator and features including direct control through the joysticks, which have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments. The new cab suspension system helps to cut vibration by 20% and reduce the sound level in the cab to 71dBA.

The DX300LC-3 excavator is powered by the Doosan DL08K common rail six-cylinder turbocharged diesel engine meeting Stage IIIB emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies.

At 159kW, the engine delivers 2% more power at a lower speed of 1,800rpm than the existing DX300LC Stage IIIA model, and factory tests are said to show a 5-10% reduction in fuel consumption, depending on the operating mode selected and the work being done.
