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%.
Komatsu used INTERMAT to take the wraps off two new Dash 7 wheeled loaders, badged WA380-7 and WA500-7. With engine emissions being the main driver, the smaller 18-tonne WA380-7 packs 142kW from its EU Stage IIIb engine to deliver improved efficiency and lower fuel consumption. The machine also gets torque converter lock-up with the function operating in 2nd, 3rd and 4th gears, and gives the loader a 40 km/h forward speed.
One of the most strikingly apparent features of the new Tier 4 Interim/Stage IIIB rated construction machines is the noise, or rather the lack of it. With engines running at usual operating speed, these emissions compliant machines are noticeably quieter.
Hyundai Heavy Industries is showcasing its new Robex 9A series of excavators – six crawler excavators and three wheeled excavators – all of which have engines that meet the Tier 4 Interim/EU-Stage IIIB standards on engine emissions. Hyundai has elected to use exhaust gas recirculation (EGR) technology – rather than liquid urea – to meet the emissions targets. “We have full automatic DPF regeneration, which is a big advantage,” said Hyundai product engineer Joachim Van de Perre. “It means that all the items
