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%.
Aimed at the 14tonne and 16tonne classes, the new Doosan DX140W-3 and DX160W-3 wheeled excavators are said to offer major performance gains over the models being replaced. As with the firm’s new crawler excavators, new cabs provide a more comfortable working environment, with improved controls and ergonomics and in-cab noise levels that are reduced by 5dBA. Both machines are powered by the proven Doosan DL06KB diesel, which delivers a 2% increase in power to 102kW and a 12% increase in torque over the previ
Doosan says its two new large Stage IIIB compliant crawler excavators in the 50tonne class offer the strength and productivity needed for heavy duty work such as large-scale earthmoving, moving rock, and secondary breaking projects found on quarrying and mining, highway, aggregate, demolition, and other construction projects. The 49 tonne DX490LC-3 and 52 tonne DX530LC-3 are said to have excellent fuel efficiency, while representing an excellent return on investment for civil engineering companies, major co
