Doosan’s DX140LCR-3 excavator
695 Doosan says that its new DX140LCR-3 excavator meets an increasing demand for reduced radius machines. This versatile unit can be used on urban, utility, highway, rail, bridge and other confined space construction sites. The firm claims the machine is designed to offer productivity, comfort, reliability, durability and reduced operating costs. The new DX140LCR-3 excavator is powered by the 196 Cummins QSB 4.5 common rail, four cylinder turbocharged diesel engine featuring the latest evolution in maintenance-free Diesel Oxidation Catalyst (DOC) after-treatment technology to meet Stage IIIB engine emission regulations. The engine runs at 2200 RPM and delivers 11% more power, with 81kW and 10% more torque (compared to the previous Stage IIIA compliant DX140LCR model, delivering up to a 5% increase in the productivity to fuel consumption ratio, depending on the operating mode selected and the work being undertaken. Arm and bucket forces have been increased by up to 8% along with the travel speed which can now reach 3.2 and 5.3 km/h in the low and high range, respectively. With the counterweight increased by 400kg to 3.5tonnes, the lifting capacities for the new DX140LCR-3 excavator have also been boosted by up to 7%.
Weighing in at 42-43.3tonnes depending on specification, the new Doosan DX420LC-3 excavator is Stage IIIB/Tier 4 Interim compliant and offers significant benefits over the model it replaces. Improvements include an increase in power, boosting overall productivity and the machine can be used in heavy-duty applications such as earthmoving, demolition and quarrying. avators offer increased performance
Doosan unveiled a new Stage IIIB-compliant DX140W-3 wheeled excavator on the opening day of INTERMAT.
The 14-16tonne machine’s 101kW DL06K 6-cylinder common rail diesel engine is fitted with exhaust gas recirculation and a diesel particulate filter to meet the emissions regulations. Productivity has been increased by an average of 5% while a new Lifting mode boosts lifting capacity by 15%. Hydraulic flow is 4% higher, increasing swing torque by an equal amount and bucket/arm forces by 7%.
