Well Thomas, when do you start building a new crane?!?!
It's true the boom is much lighter with Beat's construction. But I think it
isn't as stiff as when you use technic beams as diagonals. It could have a
torsion, but Beat's boom isn't very wide so I think he solved that.
I haven't red Beat's respond. Let me guess about the turntable: a grey one
isn't it? Did you use wormscrew to make it turn?
Yes Thomas, me neither. I really can't get enough of cranes. I know a lot of
people with LEGO cranes. Believe me, it's amazing what these people do! When
you are in the Netherlands around 13th April, you really should take a visit
to the large Modelshow Europe. You will be amazed when seeing all those
great masterpieces!!
