Caterpillar hybrid excavator

Caterpillar has done it again! The new machine is the first in an upcoming line of hybrid excavators and will be officially launched in April 2013 at the Bauma International Trade Fair in Munich Germany.  This excavator isn’t an electricity/fuel hybrid like the automobile industry has.  Cat developed a new hydraulic hybrid technology that it says allows the new 336EH to get up to 25 percent greater fuel efficiency.
