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%.
The Kohler/Lombardini group will use Bauma to update its range of air-cooled single cylinder diesel engines, unveiling the new 8kW KD15-440 engine which the manufacturer says will strengthen and improve the current 15LD series - elevating it to the top of the class within its power range. The KD15-440 is an air-cooled single cylinder diesel engine with a displacement of 441cc and an air filter that can offer, Lombardini claims, an operating life five times greater than the current version via its new high-e
Doosan Infracore Construction Equipment has launched its new Stage IIIB compliant DX380LC-3 large crawler excavator. In addition to offering what Doosan says is outstanding performance levels and exceptional fuel efficiency compared to other machines in the 34 to 42tonne market, the new DX380LC-3 excavator is said to offer improved visibility, comfort, controlability and ease of operation. A new joggle/shuttle control is said to be an exclusive feature on new generation Doosan excavators. The new DX380LC-3
LiuGong Machinery is exhibiting two of its key excavators at Conexpo, the 922D and 950E. The 950E model is aimed at the 50tonne excavator class of particular importance as it takes LiuGong’s range into a new segment for large earthmoving duties. The 950E can be configured for mass excavation applications such as truck loading and the standard model features a 3.2m3 bucket although other application-specific buckets are also offered.
