The Acco Super Bulldozer is the largest and most powerful tracked bulldozer ever made. It was built in Italy by the Umberto ACCO company. The Acco super bulldozer was constructed mainly of Caterpillar parts, however many other components were specially adapted. The dozer blade, for example, is bigger than anything Caterpillar has ever made. This bulldozer has a gross weight of 183 tons and is powered by two 675 hp (503 kW) Caterpillar engines. The super bulldozer has a blade that is 23 feet (7.0 m) wide and 9 feet (2.7 m) high, whilst the total length of the Bulldozer is over 40 feet (12 m), from the tip of the blade to the ripper on the rear. The ripper alone is about 10 feet (3.0 m) tall, being powered by huge hydraulic rams.
This bulldozer was initially built to be exported to Libya in the early 1980s to help in land development. But at that time, the United Nations endorsed and sanctioned huge trade embargoes on that country. As a direct consequence of these trade restrictions, the completed Acco Dozer was never shipped to its intended destination, but remained in Italy where it was built. This bulldozer has never been put to any operational use and was put into storage.
Acco ceased its existence when both Umberto Acco (the founder) and soon after, his son, died. In 2008, the main and secondary shops slowly turned into a dump yard of any kind of earth moving machinery, including the super bulldozer and its brother, a 200-ton super grader.
By the end of May 2012 the dozer had been moved away from the abandoned ACCO facility and is now safely stored at a local gardening company in the same town to be preserved and eventually put on display. The ACCO Superdozer moved under its own power onto the trailer that took it to the new location.
