My first real attempt to build 'big'. The boom and hook were fully motorised. I soon learned that the turn table for the crane was no were near strong enough for a crane this size.
Ezekiel, many thanks. I have seen the droid wheels you mean, I just haven't bought any yet. I have made a different stlye noe using 1x4 plate hinges and 1x4 technic beams for my new dragline.
I've got an idea... Use droid wheels as a turntable.. if you've seen the turn table of a real abraham tank, or other tanks for that matter, you should roughly know how ~
