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. The Acco Superdozer moved under its own power onto the trailer that took it to the new location.This year we celebrate the 75th anniversary of the Cat® dozer blade. īy the end of May 2012 the dozer had been moved away from the abandoned Acco facility and is now safely stored at a gardening company in the same town, to be preserved and eventually put on display. Beginning in 2008, Acco's former main and secondary shops slowly turned into a dumping ground for surplus earth moving machinery, including the super bulldozer and its brother, a 200-ton super grader. They left no legacy for managing the Acco company.

Īcco ceased to exist when its founder Umberto Acco died and his son died shortly afterward. This bulldozer has never been put to any operational use and was put into storage where it was built. As a direct consequence of these trade restrictions, the completed Acco Dozer was never shipped to its intended destination. As the Leader of Libya, Colonel Gaddafi, was heavily involved with international terrorism at that time, the United States imposed a trade embargo on that country in 1986. This bulldozer was initially built to be exported to Libya in the early 1980s to help in land development.

The ripper alone is about 10 feet (3.0 m) tall, being powered by huge hydraulic rams. The super bulldozer has a blade that is 23 feet (7.0 m) wide and 9 feet (2.7 m) high, whilе the total length of the bulldozer is over 40 feet (12 m), from the tip of the blade to the ripper on the rear.

This bulldozer has a gross weight of 183 tonnes and is powered by two 675 hp (503 kW) Caterpillar engines placed horizontally opposed, which deliver a total combined output of 1,350 hp (1,010 kW). The dozer blade, for example, is bigger than anything Caterpillar has ever made. The Acco super bulldozer was constructed mainly of Caterpillar parts however, many other components were specially adapted. It was built in Portogruaro in northern Italy by the Umberto Acco company. The Acco Super Bulldozer is the largest and most powerful tracked bulldozer ever made.
