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%.
Cummins used bauma to reveal the QSF3.8 – a four-cylinder engine platform delivering a power range of 63-89kW – which is ready to meet Stage IV/Tier 4 Final emissions regulations. Using only SCR for its exhaust after-treatment process, the QSF3.8 avoids the need for either DOC or DPF as a result of using a high-efficiency catalyst to convert oxides of nitrogen at lower exhaust temperatures while requiring only low doses of DEF, said the company.

Doosan’s new DX140LCR-5 15tonne reduced tail swing crawler excavator is powered by the Perkins 1204F engine, which combines reduced fuel consumption with the power and torque of larger engines with a smaller displacement.
The new Perkins 1204F engine provides a 6% increase in power with an output of 85.9kW at 2,000 rpm and a 3% increase in torque. Swing torque has also been boosted by 28%.
Trouble-free operation is guaranteed by meeting Stage IV emission regulations without the need for a diesel parti
Doosan Construction Equipment has shown a prototype of its 6tonne DX62R-3, a replacement for the DX60R. Due to be launched in the second half of the year, the machine delivers a 33% increase in hydraulic flow from a new load sensing system. Digging forces are said to be greatly improved, with bucket force now up to 4,400kg, and increase of 7%, while dipper arm force is up to 2.9tonnes. This improved performance has been combined with a longer arm for a larger working range. The machine uses the same cab tha
