After a long surch finally managed to track down all the Colossus 6000 cranes but the story is not finished yet
One crane that Coles built has a strong fascination for lovers of cranes, an oddity that probably should never have been built The Colossus 6000.
Well after alot of detective work we have managed to put together an PDF E-Book about the largest crane that Coles ever built the Colossus 6000, and managed to get photographs of all of them. Sounds like a big project however there were only six ever built and this is the story about them.
The Book can be viewed or downloaded by clicking on the cover picture to the Left. -- It will open in a new window displaying in Google viewer, you can read it here (not as good in quality as Acrobat) or use the file menu on the viewer to download a copy onto your computer then read in Acrobat (the downloaded file is better quality viewed in Acrobat)
