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%.
With the Tier 4 interim/Stage IIIB emissions requirements due next year, further upgrades will be required for all wheeled loaders sold in Europe and North America.
In the mean time manufacturers are focussing on improvements that cut cycle times, boost productivity and reduce downtime for example.
From Doosan comes the DL420 wheeled loader, which takes over from the previous DL400 and is aimed at use in a range of materials-handling work. The DL420 features a 4m3 bucket and is a 22.3tonne machine that
Yanmar’s industrial engines division used Conexpo to show off its latest compact diesel engine equipped with a diesel particulate filter (DPF). Offering a power rating of 53.7kW at 2500rpm, the 3.3litre 4TNV98CT combines common rail electronic injection and cooled exhaust gas recirculation with the DPF system.
