Any clue what it may weigh?

thanks

Since these things are predominantly made of standard structural
steel
components, a bit of measuring and comparing to specs in a
structural
steel chart should tell you the weight per foot for the
materials and a
bit of calculating for the total.

Thanks. It makes sense. The problem is this. It is 2.5 hours away
from
me. I have to tell my driver how much of it to pick up without
ending
up overweight.

Look at this picture to get an idea. You can kind of figure out
the
size, the main bridge (top part of the picture) is exactly 50 feet
long and about 48" high.

I assume you have actually seen the crane in person. So you are
wanting people that have never seen the crane to give you a better
estimate than you can generate.

I have not seen it.

That's the problem.

I also want to be able to estimate weights of cranes that are still
up
in the air.

However I understand that portable truck scales are made ( just
like
the ones the highway patrol will have ) and they might be something
that you could use. Sorry I have no idea of the cost or the
manufacturer.

Yes, good point.

I don't do anywhere near the heavy rigging that you do, so this very
portable 10,000 Lb hydraulic load cell is enough to weigh anything I
might want to lift. I paid $60 for it
