Doosan launches new DX140LCR-3

13 Aug 13 Doosan Construction Equipment has launched the new Stage IIIB-compliant DX140LCR-3 excavator.

The 15.3t reduced-tail-swing crawler excavator is designed to meet an increasing demand for reduced-radius machines as an alternative to conventional models for work on urban, utility, highway, rail, bridge and other confined-space construction sites.

The DX140LCR-3 is powered by the Cummins QSB 4.5 common rail 4-cylinder turbocharged diesel engine featuring the latest evolution in diesel oxidation catalyst (DOC) after-treatment technology to meet Stage IIIB engine emission regulations.

The passive catalyst system is claimed to offer the simplest, most reliable after-treatment technology in this very competitive power band and the lowest cost of operation.

The engine runs at 2,200rpm and delivers 11% more power and 10% more torque than the previous model.

Arm and bucket forces have been increased by up to 8% along with the travel speed, which can now reach 3.2km/hand 5.3km/h in the low and high range, respectively.  Owing to the incorporation of a heavier counterweight, the lifting capacities have also been boosted by up to 7%.

The new cab offers more space for the operator and features such as direct control through the joysticks, which have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments.

The control console offers new functionality with an attachment control function as standard, allowing the operator to record and select hydraulic flow and pressures to operate up to 10 different attachments.

Standard features also include an adjustable air conditioning system plus a high quality heated air suspension seat.

The new DX140LCR-3 crawler excavator has a more robust undercarriage with reinforced components, such as track links, track springs and sprockets.  The boom and arm have also been strengthened by increasing the metal thickness at critical points and using reinforced bushings.
