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%.
A combination of engine and driveline technologies will reduce fuel consumption and increase performance in new generation, low emission machines
A wide array of new engine and driveline technologies being developed will help reduce emissions and fuel consumption, while increasing performance in the
latest machines coming to market. With engine manufacturers focussing on the Tier 4 Interim/ Stage IIIB and following Tier 4 Final/Stage IV emissions requirements for North America and Europe, sophisticated
Like its fellow new 9A series hydraulic excavators with engines above 130kW, the engine on the Robex R380NLC-9A hydraulic crawler excavator from Hyundai Heavy Industries (HI) comes with an EGR and diesel particulate filter (DPF). The DPF is said to be automatically or manually regenerated, ensuring compliance with all NOx and PM values. According to Hyundai HI, DPF filters only need to be cleaned after 5,000 to 6,000 hours in operation.
