![]() ![]() “Our team generated 93 patents involving all systems of the concept,” adds 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 tested thoroughly in multiple demanding applications 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,” says Alexander. 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. It quickly became evident that a new track design and improved undercarriage were needed to meet the production and durability goals for the new dozer. The D10 research team established a set of design goals for the new dozer: high productivity modular design simplified maintenance operator efficiency and transportability. The challenge of beating the competition in our core product was a tremendous incentive,” recalls Ron Krolak, track-type tractor chief engineer, retired. It was highly successful because of the total team effort. “The development and product introduction involved every discipline of the company. To address the market’s needs, Caterpillar tapped a team of Research and Engineering personnel to develop a new, more powerful dozer, the D10. “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,” adds Alexander. Contractors working in predominantly hard rock applications also demanded a design that improved track longevity and durability. Power was supplied by the 700 hp (522 kW) D348, V12 diesel engine.Ī changing industry in the late 1960s and early 1970s stretched the D9 to its productivity limits, and the mining industry led the charge for a dozer with more and more horsepower. Offering 50 percent higher productivity than Caterpillar’s largest dozer of that era, the D9 dozer, the D10 weighed over 190,000 lb (86 180 kg) and measured 15 ft (4,6 m) tall, 12 ft (3,7 m) wide and slightly more than 31 ft (9,4) long. The result of the team’s out-of-the-box thinking was a machine with no rival for weight, power or productivity. “We bucked conventional wisdom with the D10 and tinkered with a centerpiece 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 radically different 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. After looking at the size and weight of a crawler tractor, our professional specialists are able to recommend the best trailer for transport.Forty years ago, Caterpillar rolled off of its production lines 10 pilot models of the world’s largest, most powerful dozer, destined to leave a lasting legacy on the industry. Ensure the size and weight of the crawler tractor you get can fit on a trailer for easy transport. A used crawler tractor might end up being a mistake if it's poorly maintained. This way, you are able to check if its performance will meet your needs or now. When buying a crawler tractor, thorough inspection is important. The specs and dimensions of the crawler tractor you buy should offer you efficiency, high production, comfort and ease of operation. For tough terrains, a powerful crawler tractor with high stability should be ideal. If your job site is congested for example, you need to look for a crawler tractor that can access it without a problem. What is a Caterpillar Crawler Tractor Used For? After looking at the dimensions and specs of crawler tractors, you’re able to buy a new or used one with confidence. You can find specs, length, width and height of any crawler tractor by searching for its manufacturer, model or industry. This way, the crawler tractor specs and dimensions you look for, will be in reference to your job site needs. ![]() Before you start looking at the specs, weight and dimensions of a crawler tractor, you should know where it will be used and the job size. ![]() When looking for a new or used crawler tractor, finding one with specs and size that meet the requirements of your job is important.
