Rumors have been flying around, but now it's official. Caterpillar will offer an industry-first track-type tractor. This thing is AWESOME, and is another example of Caterpillar leading the construction equipment industry in technology and innovation.
Caterpillar Announces the First-of-Its-Kind Electric Drive
Track-Type Tractor
"PEORIA, IL— In a move that further positions it as the world’s leading manufacturer of earthmoving equipment, Caterpillar Inc. (NYSE: CAT) is unveiling the first innovative AC electric drive track-type tractor in the industry. The revolutionary electric drive system developed for track-type tractors gives the D7E an unmatched balance of power, efficiency, control and maneuverability. The machine will be showcased at CONEXPO/CON-AGG 2008 March 11-15 in Las Vegas, Nevada.
“The D7E offers a quantum leap in customer value through significant productivity increases and reduced owning and operating costs,” said Mark Pflederer, vice president of Caterpillar’s Heavy Construction & Mining Division. “This is another example of Caterpillar’s global technology leadership and commitment to sustainable innovation which is not only good for our customers economics, but the environment as well.”
From a performance standpoint, this new product demonstrates Caterpillar’s commitment to the industry with a machine that does more work and consumes less fuel and parts while providing customers with lower operating costs. Caterpillar plans to commercially introduce the D7E in select markets during 2009.
“From an environmental sustainability perspective, the D7E uses substantially less fuel per hour – dramatically reducing the amount of carbon dioxide emissions,” said Caterpillar Group President Stu Levenick. “This revolutionary design consumes fewer resources over its working life than any other track-type tractor in its class. All major components are engineered to be rebuilt or reused in the future.”
The D7E is in the 60,000-pound (27 000-kilogram) weight range and is powered by a Cat® C9 engine producing 235 horsepower (175 kilowatts). A traditional mechanical transmission is not needed, because the variable speed electric motors serve the function of a continuously variable transmission. The electric drive train has 60 percent fewer moving parts compared to previous D7s. The electric system also provides power to auxiliary components so that no engine belts are needed. The C9 engine, complete with ACERT® Technology, meets U.S. Tier 3 emissions standards, and the tractor has been designed with Tier 4 in mind. The new D7E has other innovative new features including an exclusive center-post cab, beltless engine and SystemOneTM undercarriage."
