Environmentally Friendly, High-Efficiency Hybrid Excavator

Atlanta, GA, April 6, 2009 – Doosan Infracore has expanded its development on its hybrid excavator with enhanced energy efficiency and lower exhaust emissions.  The Doosan hybrid excavator, slated for launch by 2012 in North America, will provide significantly reduced fuel consumption and is designed to reduce the environmental impact of CO2.  The innovative Doosan hybrid excavator will be equipped with a diesel engine, electric swing motor, electric converter and an ultra-capacitor that will store excess energy during turning and light-duty operations.  The reserve electricity will then be used to assist the power of the engine during heavier work; allowing the engine to maintain low revolutions and high efficiency combustion during acceleration.  Such a system will save fuel and reduce exhaust emissions; thus creating additional value for Doosan customers.


Doosan Infracore™s first hybrid excavator will be a 22-ton model with an approximate 35% reduction in CO2 and fuel consumption when compared with the DX225 standard hydraulic excavator.  The increase of fuel efficiency will save approximately $10,000 in fuel cost per machine each year*.


We are committed to bringing the most competitive and innovative technology to market, and Doosan is focused on developing a fast, fuel efficient and reliable hybrid for its customers, said Michael Stanley, President/COO, Doosan Infracore America Construction Equipment.  Our hybrid machine will provide best-in-class support with innovative technology.


Doosan Infracore has shown consistent commitment to its global presence in the construction industry through its acquisitions of Bobcat and Moxy Trucks in 2007 and 2008 respectively.  The development of the 22-ton hybrid excavator is yet another step in offering the North American market a full solution for its construction equipment needs.
