New Holland Previews 7-Ton Hybrid Hydraulic Excavator

Fri February 09, 2007 - National Edition

New Holland has unveiled a prototype Hybrid 7-ton (6.3 t) class crawler excavator.

The Hybrid excavator was designed by Kobelco Construction Machinery America Co. Ltd., in partnership with New Holland. Both Kobelco and New Holland are brands of CNH Global N.V.

Featuring a diesel engine and a battery-powered motor, the Hybrid offers the operating performance capabilities of a traditional diesel-powered 7-ton class excavator. Fuel consumption and carbon dioxide emissions have been reduced by 40 percent on the Hybrid, as compared to New Holland’s current diesel engine base model, the E70 mid-size excavator.

“Over the next few years, engine technology will evolve drastically,” said Paul Golevicz, New Holland marketing manager.

“At New Holland, we are accelerating the development of environmentally friendly construction equipment with a focus on reducing carbon dioxide and greenhouse gas emissions.”

The Hybrid’s battery-powered motor enables the use of a smaller diesel engine, reducing noise levels and lowering emissions and fuel consumption — without sacrificing digging performance.

Serving as a power generator to charge the dedicated battery, the electric motor assists the diesel engine by driving the hydraulic pumps connected to the boom, arm and bucket cylinders, and travel motors. The battery supplies electricity to both the electric motor and the electric swing motor.

Before bringing the Hybrid crawler excavator — or any other environmentally friendly equipment — to market, Golevicz said New Holland will continue to refine the prototype’s performance, while scanning the horizon for future market trends and changes in operational requirements.
