To most Australians a ACCO is something different a bit about this has appeared on the Mack truck forum so I thought I have never heard it mentioned on here so I best share it with you all


The Acco super bulldozer was constructed mainly of Caterpillar parts, however many other components were specially adapted. This bulldozer has a gross weight of 183 metric tons and is powered by two 675 hp Caterpillar engines placed horizontally opposed, which deliver a total combined output of 1,350 hp. The super bulldozer has a blade that is 23 feet wide and 9 feet high, whilst the total length of the Bulldozer is over 40 feet, from the tip of the blade to the ripper on the rear. The ripper alone is about 10 feet tall, being powered by huge hydraulic rams.

To add a bit more to this interesting story, here's some more info I had gathered up from the net about ACCO over the years. My understanding was the Italian entrepreneur Umberto Acco had secured a large pipe-laying contract with the Libyan Government pre-sanctions days and had modified mostly Cat equipment for the job including the dozer, several graders based on a 657 Tractor-unit and draft frame, back-fillers and other specialized equipment specifically for the said job. Here's some of those pics - these photos are not mine, just found on the world-wide web as mentioned, photo credits to the copyright owner if any.

so with all that horsepower, it looks like they had two final drives on each side, probably to split the tourque between two smaller final drives instead of making one massive one?

Hi, Folks.
As I understand it, the Acco dozer has never struck a 'blow in anger'. Both it and the 'real' Acco grader were apparently completed and about ready for delivery when a trade embargo was slapped on Libya over their part in international terrorism. Again as I understand it, they were built to an order from Libya's dictator, Colonel Ghadaffi, 'cos he wanted to do some major development of desert country for farming and irrigation.

I have been told that grader, which was even bigger and more powerful than the dozer at 1,700 horsepower and 200 tons, was used a for a couple of beach reclamation jobs in Italy before being mothballed and then eventually scrapped somewhere in the early 2000s.

What few people seem to be aware of is that Acco built a 'prototype' grader prior to building the 'real' grader. The 'prototype' was a mere 160 tons. I have heard that it too has been scrapped. I do have a photo of it but don't have it to hand at the moment as I am on a another computer.

Just my 0.02.

Hope I'm not stealing your thunder here Deas - this is the other pic I have of an ACCO grader now that you've mentioned another, maybe that's it?. Again from the net when I was doing a study on Acco- built machines. Appears to have an articulated steering arrangement in the rear similar to a Raygo Giant Leveler. And here also is another pic of the trench back-filler. Umberto Acco may have been Itay's answer to Buster Peterson, master designer of specialized purpose-built equipment incorporating major components from existing machines,

That trencher tractor appears to have been fitted with a V8. I guess Acco was fond of V8s

What I have heard was that the little dictator wanted them to quickly demo blocks of infidels as they were weeded out. The dozer was rescued and there is plans on tap to get it to public display. I seen a video a couple years ago off it getting loaded from under the bridge.

Here's a pic of the operator station and controls. Photo credits are attributed to the person/s who own the copyright if any, these were posted these on the world-wide web. I won't bother putting any more pics up, they can easily be found on the internet. Looking at the final drive arrangement, it appears there may be a chain-drive like a 16G chain box connecting the upper and lower sprockets. It would be good to see some engineering drawings of this thing to get some details of the mechanical side.
