The Cat D7E bests the 2010 EPA emissions requirements (toughest in history), potentially provides up to a 20% reduction in fuel consumption, allows a 10% increase in material movement, includes 60% fewer parts and has up to a 50% longer service life. Caterpillar presented the keys of the first innovative AC electric drive track-type tractor in the industry to long-time customer, TJ Lambrecht. The revolutionary electric drive system developed for track-type tractors gives the D7E an unmatched combination of power, sustainability, control and maneuverability. “Our customers are being challenged to do their work more efficiently with less impact on the environment,” said Caterpillar Group President, Doug Oberhelman. “The D7E demonstrates Caterpillar’s commitment to the industry with a machine that does more work and consumes less fuel and parts, providing customers with lower owning and operating costs.” Oberhelman was recently named Caterpillar Vice Chairman effective January 1, 2010.
