The axles of my crane were supported as well. I put six black bricks under
the chassis. You nearly couldn’t trace them. Many people thought the crane
was supported only by it’s heavy support arms. But as LEGO-ist you know
that’s far from possible.

From experience I know that pieces breaks sometimes. Especially when you’re
building a large model like a crane. Gears will break because of the heavy
weights and the great forces. Technic beams will damage etc.
At the moment I’m almost finished with a new truck: a tri-axle tractor with
a self unloader on its fifth wheel. It’s my third conveyor belt trailer
since I’m building original vehicles. You can say that I already know how to
build such a vehicles but less is true. This time I made a whole new
concept. As probably expected some pieces damaged during the test. One time
a bush was turning into a hole of a technic brick. I was lucky to stop the
machine immediately. With my second self unloader I had the same problem,
but I traced it too late: many pieces where damaged and then a ½ bush was
pierced into a technic brick! I still have it as a reminder. I didn’t knew
that was possible. Hopefully it will work this time. Tomorrow I will finish
the model so I can show it and demontrate it during a local event (more than
15.000 visitors!).

Thanks. Who knows what you can build in the (near) future! Who isn't
interested in cranes? I know many interested people!!

I prefer building real working models. But they always must be like the real
ones. So I try to combine Technic with Model Team. I use the old technic
stuff, like 12V motors. These are much stronger than today’s crap. Nowadays
LEGO isn’t interesting anymore.
Hope to see some of your work soon.
