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%.
Several new machines are being launched by Doosan and sister firm Bobcat at bauma China. A key launch for the Doosan Heavy display will be its new DX700LC, the top-of-the-range model in the Doosan excavator range. The 70tonne DX700LC excavator is designed and built to meet the needs of heavy duty quarrying applications as well as major infrastructure projects. It offers several features intended to boost productivity, comfort, reliability, durability and uptime. The DX700LC model will be shown alongside the
Bobcat, a division of Doosan, is showing a prototype of the E85 midi excavator, an 8.5tonne machine powered by a Yanmar 44.3kW Stage IIIB engine. The machine meets the emissions standard through the use of exhaust gas recirculation and a diesel particulate filter (DPF). The reduced tailswing excavator has 4% more power than the previous E80 model, yet is said to offer a 7% improvement in fuel economy. Bucket digging force is also up 7%, and 6,600kg.

2012 sees the start of a new wheeled excavator programme from Liebherr, and the A916 represents the first fruit from the project. Replacing the A316 Litronic, the new A916 has been developed to meet Stage IIIB emissions requirements and has an operating weight from 17-18.1 tonnes depending on specification. Power comes from a four-cylinder 110kW engine with common rail fuel injection, EGR and DOC – a DPF is available as an optional extra for those working inside buildings.
