The Worlds Biggest Grader
|
The Worlds biggest earth moving grader is the Acco-Grader. It is a custom made 'one-off' built in Italy by the Umberto Acco Company in 1980.
The Acco Grader was powered by 2 engines. A 1000hp engine was in the rear part of the Grader whilst a 700hp engine was at the front giving a combined power output of 1700hp! 1700hp was required too, when considering the Acco Grader weighs in at 160 Tons ! The Grader was initially built for export to Libya similar to the Acco Dozer of the same company, but due to trading restrictions with Libya at that time, the Grader was never shipped out and remains in Italy to this day.
The Acco Grader has twelve big tyres all round, doubled up on each wheel hub, this was a measure taken to distribute some of the weight of the grader. With its 33 foot long 'grading' blade it was designed for some serious earth moving capabilities. The function of the Grader is to even and level the ground out and make it as flat as possible for the construction of highways or building development.
The size of this grader can be appreciated a bit better when photographed with a person standing on it. The Grader is now unfortunately just a redundant piece of machinery having never been put to work but just sits in a huge shed. More information about this vehicle will be posted when available. Special Thanks to 'Herrman' in Italy for suggesting this vehicle for inclusion onto my site.
