The choice in powertrain and dozer blade configurations allows customers to tailor the machine to the application, whether it’s a large fine-grading job to bulk earthmoving.Ī lot to love with the Large (D8-D11). Large Cat dozers are built to take on the world’s most demanding work. Next Generation models include factory-integrated Cat Grade technology plus, you’ll find the industry’s first high-drive electric drive in this size class. Another major feature? Versatility. Major features with the Medium (D4-D7). Medium Cat dozers deliver industry-leading fuel efficiency and easy maintenance features that reduce owning and operating costs. Plus, the new GRADE technology has really made the small dozer valuable on the jobsite! Plus, with a big selection of undercarriage, drive train and blade configurations, customers can customize their new dozers to accommodate virtually any job requirements.Īll about the Small (D1-D3). Quick to move from site to site, with the right combination of speed, power and accuracy, small Cat dozers are versatile construction workhorses. Whether the job is moving material or finish grading, there’s a Cat® dozer made for it - small, medium or large. It allows the operator to control the dozer remotely, from anywhere in the world.
Today’s operators can use our latest Command for Dozing. Eventually dozers progressed to having an onboard computer that could control the blade for the operator to produce a predetermined design. These were easier to use and could lift up or push down. It started with cable controls that could only lift up, then hydraulic controls came along. Operator In Mind From Lift Up to Remote ControlĪnother big change in dozers… how the operator uses the controls. Interstate Highway System, the Three Gorges Dam in China, and the widening of the Panama Canal, just to name a few. These machines worked on some of the modern world’s greatest engineering projects, including the U.S.
The Caterpillar track-type tractor quickly became known as a “dozer” and the legend was born. The performance of experimental and first-production models gave assurance that these new items of earthmoving equipment would sustain and enhance the high reputation of Caterpillar products.įirst shipments of Caterpillar track-type tractors with accompanying Caterpillar dozer blades were made later that year. Throughout 1945, engineers performed exhaustive tests on this new product at the company's proving grounds in Illinois and Arizona, and operators tested the attachments at various locations throughout the United States. The first Caterpillar tractor with the new dozer blade left Peoria, Illinois, in 1945. Dozer blades originally came in straight, angling, and "U" shapes, both cable- and hydraulically- controlled. In early 1945, Caterpillar began developing its own line of dozer blades that met Caterpillar specifications and quality standards. A Legend Is Bornīefore 1945, suppliers designed and sold earthmoving attachments designed specifically for Caterpillar tractors. They continued to make dozers in small quantities until they were discontinued after their merger with the C.L. In 1914 the Holt Manufacturing Company, one of Caterpillar’s predecessor companies, introduced a dozer blade in front of the machine that was controlled by a rope windlass fastened to the tractor’s main frame. Their main purpose was to spread loose dirt out over a fill as it accumulated. They were made of wood and affixed to the front end of a pole that was pulled by horses or oxen. But even as late as the 1800s, dozer blades were crude by any standards.
The origin of the dozer blade is buried in the past as deeply as the origin of the wheel. Hear the story of the dozer – from blade to machine – and find out why it’s a fan favorite. Today, the term also refers to the rugged machines built for tough jobs pushing dirt. Yep, the dozer part. The term “dozer” originally referred to a steel plate and an operating mechanism attached to the front of track-type tractors. Some say it may be the ultimate part provided by Caterpillar to its customers. This year we celebrate the 75th anniversary of the Cat® dozer blade.
