![]() However, customers can choose custom colors for example, did you know that machines destined for landfills are often painted blue? That’s done in an attempt to fool birds into thinking they’re looking down at water. But somehow they still arrived at exactly the same paint scheme as before: uniform dull yellow. The company says the D7E project involved almost 500 engineers over the course of roughly a decade to produce this completely new dozer with the first-ever electric drivetrain. In Caterpillar’s lineup of dozers, the D7E fits roughly in the middle at the light end, there’s the 17,000-pound D3, which might be used for small commercial construction, and at the other end, there’s the mammoth D11, an intimidating 250,000-pound brute built for mining work, with a nine-foot-tall blade and nearly seven-foot-tall tracks. This 60,000-pound D7E-that’s as much pork as 10 Range Rovers-is about six inches longer than a Chevy Suburban (including the blade), but it’s more than nine feet wide. in 1925, and still produces one of the biggest chunks of revenue for the world’s largest maker of construction and mining equipment. uh, wait, what is it again? “We consider this a diesel-electric hybrid powertrain,” says senior project engineer Keith Heiar, “but we’re not labeling it with the ‘hybrid’ word on the side of the machine.” That’s because, although the company’s first-ever electric drivetrain is the greenest thing in the stable, it doesn’t have auxiliary battery storage and therefore doesn’t fit the category as defined by the automotive world.Īmong Caterpillar’s almost 30 different categories of machines, the D7E belongs to the rather clumsily alliterative and repetitive “track-type tractor” unit these are commonly referred to as “dozers.” This type has a long history, dating back to the formation of Caterpillar Tractor Co. In addition to machine protection against impacts and airborne debris, these specialty dozers can be ordered with an impact-resistant cab, application-specific undercarriage and a specialty blade.From the August 2010 issue of Car and Driver.Ĭaterpillar’s new D7E bulldozer is the world’s first hybrid-uh, electric. The D7 can also be ordered with specialized guarding to take on the challenges of Waste/Landfill work and Forestry/Land Clearing.The D7 is available in Standard or Low Ground Pressure (LGP) configurations, with a variety of blade and track shoe choices to optimize the machine for the intended application.Cat LINK telematics technology offers a range of security, accessibility and management features.Cat COMMAND for Dozing offers line-of-sight (LOS) control using an over-the-shoulder console, or a non-line-of-sight (NLOS) option using the Cat Command Station to run the machine remotely.Customers can also add factory-integrated Cat GRADE with 3D.ARO with Assist is a grade-ready technology option bundled with basic blade control and a new set of assist features that just work in the background to help operators get more done in less time. ![]() Standard High Definition rearview camera shows prominently in the main display.Easy-to-use 10-in (254-mm) touchscreen operator interface.Redesigned cab, common with the D5 and D6/D6 XE, improves comfort and productivity.Elevated sprocket undercarriage delivers better ride and balance, as well as increased penetration force.The D7 moves up to 8% more material per hour than the D7E, with about 6% more weight and 12% more horsepower.(29,776 kg), the new D7 dozer replaces the D7E At 265 hp (197 kW) and an operating weight of 65,644 lbs.A fully automatic 4-speed transmission offers optimal fuel and dozing efficiency, plus ease of operation.The new Cat® D7 dozer offers high drive undercarriage design, increased performance and an array of easy-to-use technology features to help operators get the most from their bulldozers.
