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%.
Caterpillar is introducing a revised line-up of 20-24 tonne E Series crawler excavators at Intermat 2012. The 320E, 323E and the reduced radius 320E RR adopt the EU Stage IIIB Cat C6.6 ACERTTM engine, providing reduced emissions and fuel consumption savings of up to 11% compared to other D Series models. A wider range of cab seating, including heating and cooling options, comes with the new E Series crawler excavators. Time delay lighting, additional safety handrails and improved serviceability are also sai
With an operating weight of 83.8 – 86tonnes, Hitachi’s giant ZX870LCH-5 excavator is said to be built to operate on the most demanding job sites, such as large-scale construction projects and in busy quarries. The model incorporates the HIOS IIIB hydraulic system, said to allow for faster operation with lower fuel consumption and increased front speed. The ZX870LCH-5 is claimed to have 6% more productivity in H/P mode compared to the previous Zaxis model. Swing torque is also said to have increased by 9% an
The new Stage IIIB compliant DX420LC-3 large crawler excavator has been unveiled by Doosan Construction Equipment. Compared to the model it replaces, the new excavator is said to offer several improvements, including a substantial boost in power, resulting in significant increases in performance specifications such as drawbar pull, arm and bucket digging forces and lifting capacities to provide a much higher overall productivity. The DX420LC-3 excavator is designed to handle a broad range of applications s
Komatsu America’s new compact hydraulic excavator is designed for increased versatility and, ultimately, lower operating costs.
Applications for the PC55MR include a variety of construction, utility and landscaping applications.
The compact excavator has an operating rate between 5150-5795kg. A 28.3kW SAA4D88E-7 engine, featuring auto decelerator and economy mode, helps reduce operating costs.
The SAA4D88E-7 Tier 4 Final engine uses Exhaust Gas Recirculation (EGR), and a high-pressure common rail fuel in
