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%.
The wide array of crawler excavators on the global construction market has led to strong competition between suppliers, each of which is keen to stay ahead of its rivals. All the major international manufacturers are introducing new models in North America and Europe for 2014, with key performance upgrades.
From Doosan comes the 22.5tonne DX225LC-3, which is said to offer increased performance and lower engine emissions and is aimed at one of the most highly competitive segments of the market. The machine
Doosan’s new Stage IIIB-compliant DX300LC-3 and DX340LC-3 crawler excavators are said to offer 6% to 17% higher productivity, along with fuel saving and reduced costs. The 30 and 35tonne machines have a new ROPS and OPG-certified pressurised cab. A heated air suspension seat and a new cab suspension cut vibration by 20% and reduce the sound level in the cab to 71d(B)A.

Both machines are powered by Doosan’s DL06K ‘common rail’ six-cylinder turbocharged diesel engine, said to meet Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. The engine has a displacement of 5,890cm³ and is said to deliver 15% more power [82 kW @ 1850RPM] than previous Stage IIIA models. The engine also delivers 11% more torque (49.5kgf.m) in the DX160LC-3 model. Doosan said that factory tests had
