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%.
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.
Following its summer 2013 launch, Bobcat’s Conexpo debut-making E63 Compact Tail Swing excavator is said to have better joystick controls, lift capacity, arm and bucket forces, and drive performance than previous models.
Replacing the E60, the E63 is the second-largest machine in the company’s compact excavator family. The 6.3tonne excavator features a number of operator conveniences including a new blade float, multi-function joysticks, colour instrumentation panel and an auto-shift drive system.

Caterpillar has developed its 312D/D L Series 2 excavator as a durable machine with low operating costs for sale in developing markets. Power for the 312D/D L Series 2 excavator comes from a Cat 3054C diesel rated at 67kW that meets Tier 2 and EU Stage II emissions regulations. The new model is available in standard and/or long undercarriage configurations, with operating weights from 12.9-13.9tonnes depending on the specification.
