Doosan Infracore Expands Development on Hybrid Excavator

Doosan Infracore America, Suwanee, Ga., has expanded development on its hybrid excavator with enhanced energy efficiency and lower exhaust emissions, according to a company press release.

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 company says.

The 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.

Doosan Infracore’s first hybrid excavator will be a 22-ton model with an approximate 35 percent reduction in CO2 and fuel consumption when compared with the DX225 standard hydraulic excavator, the company says.

“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.”
