Germany This was a first for me. A Mobile Tower crane collapsed. It landed on a number of cars. I can't say that I know enough about truck mounted tower cranes. They are common in Europe but in the US we generally haven't had them. I've often heard of axel weight issues but I think that those issues are fixed at this time. Will someone give me 2 million dollars so that I can buy one and go to work with it? This particular one is a Liebherr and the truck frame was horizontal and on it's outriggers.
