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%.
Two new short radius excavators are being introduced by Case Construction Equipment at INTERMAT. The Japanese-built CX235C SR and a prototype CX145C SR use low emission Isuzu engines with cooled EGR and a DPF to meet stage IIIB emissions requirements, and Case reckoned the new engines provide a 17.5% fuel consumption improvement over previous models, while simultaneously delivering up to 7% cent faster cycle times.
The excavator and wheeled loader segments represent massive sales volumes for manufacturers, so new model development is prioritised - Mike Woof writes.
The crawler excavator segment accounts for a substantial portion of total sales of construction machines. With this in mind, it is no surprise that this is a market segment for which manufacturers prioritise a significant proportion of their research and development budgets. Wheeled loaders, while not selling in quite such large numbers as crawler excava
JCB says its Ecomax Stage 4/Tier 4 Final engine can be engineered into many existing machines without needing additional space by using a ‘one can’ selective catalytic reduction (SCR). According to the company’s chief technology officer, Tim Burnhope, in many cases the mini SCR on the Stage 4/Tier 4 Final Ecomax engine can be positioned in the same space occupied by the exhaust silencer on previous generations. He said, “Our engine is already so clean that we only need 2% to 3% of urea, which allows us to u
