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%.
Hyundai is introducing a new top end excavator in the 100tonne-plus sector. The company says this endorses its commitment to large-scale investment in developing new products and new market opportunities. “Building on Hyundai’s experience with the successful 50-80tonne high capacity models, the all-new 120tonne R1200-9 has been conceived with an eye on the expanding worldwide mining and quarrying sector, where the demand for efficient, large-scale mass excavation in minerals extraction and overburden remova
Engine manufacturers have had to jump through regulatory hoops in recent years, meeting requirements for diesels with ever cleaner exhaust emissions. When this programme was first proposed, many believed the final aims could not be achieved. However on January 1st 2011, the Tier 4 Interim/Stage IIIB emissions regulations will come into force in North America and Europe and all the major diesel manufacturers will have suitable products at the ready. The Tier 4 Interim/Stage IIIB emissions regulations require
Ideal for quarry-based applications, the new Doosan 40-50 tonne DX420LC-5, DX490LC-5 and DX530LC-5 are the company’s largest Stage IV/Tier 4 Final compliant crawler excavators.
The operating weights of the DX420LC-5 and DX490LC-5 have increased by 700kg and 500kg respectively compared to the previous LC-3 models. Lifting capacities have increased by an average of 5% on all three models, except for the DX530LC-5, where the lifting capacity over the side has also increased by 12%.
