![]() “It didn’t look like any traditional Cat dozer,” explains George Alexander. While initial testing proved the efficacy of the resilient undercarriage with elevated sprocket design, some remained sceptical about the new design. ![]() The elevated sprocket design was also better able to absorb ground shocks for longer life and greater operator comfort. “Our team generated 93 patents involving all systems of the concept,” adds Ron Krolak.īy separating the drive sprockets from the track roller frame and elevating them above the tracks, more track remained on the ground for improved traction. Two years of testing led to the first elevated sprocket patent application and ultimately building the first two D10 test models in August of 1973. ![]() The new resilient track with elevated sprocket design was thoroughly tested to verify its durability, and it showed significant potential for improving undercarriage durability for extreme tasks. “We worked on undercarriage geometry a lot, and within six months we had it operational,” George Alexander says. Engineers started by flipping the final drive for a D9G upside down. With management approval in 1970, a test bed was built for the new track. The challenge of beating the competition in our core product was a tremendous incentive.” “It was highly successful because of the total team effort. “The development and product introduction involved every discipline of the company,” recalls Ron Krolak, track-type tractor chief engineer, now retired. To address market needs, Caterpillar put its research and engineering team to work on a new, more powerful dozer. “It worked great for dirt operations, but interstate and heavy rock applications were hard on the solid bottom tracks that were a part of all dozer designs of that era.” “The D9 dozer was the best track-type tractor of the day,” says George Alexander. Power was supplied by the 522 kW (700 hp) D348, V12 diesel engine. It weighed more than 86 tonnes (190,000 lbs) and measured 4.6 metres (15 ft) tall and slightly more than 9.4 metres (31 ft) long. The D10 was 50% more productive than Caterpillar’s previous largest dozer of that era, the D9 dozer. “We bucked conventional wisdom with the D10 and tinkered with a centrepiece that was a part of the Caterpillar product line since the company was formed in 1925,” says George Alexander, a retired Caterpillar engineer who served on the D10 research team and one of four individuals named on the patent for Caterpillar’s elevated sprocket design. The Cat D10 dozer’s radical new design, high weight and horsepower, and resilient undercarriage answered the growing calls from large mining and big heavy construction operations for a more powerful dozer. It was September 1977, a month when David Soul wanted a Silver Lady to take his hand and Meri Wilson had an interesting visit from a Telephone Man, that Caterpillar rolled off of its production lines 10 pilot models of what was world’s largest, most powerful dozer. It weighed 180,000 pounds (82,000 kilograms). Later versions were weighed at 190,00 pounds (86,000 kg).Menu Fast Index My Account FREE Newsletters Construction Index Cat D10 FAQ How much horsepower does a D10 Cat have?Ĭat D10 engine produces a 700 hp (522 kw) How big is a Cat D10?Ĭat D10 Cat D10 could be ordered with up to 19 feet (5.8 meters) U-blade.
