I understand the replies about safety and how it would become unstable
with
the load able to swing outside the wheel area and cause the crane to tip
over, etc. But, since this is a metalworking newsgroup, and most cranes
that I know of, including the 60 ton crane we have at work, are
constructed
using metalworking, I don't agree with the replies that say I shouldn't do
it.

I don't want to hear from your estate's lawyer about how you killed yourself
by following my advice. We gave you some general guidelines and problems to
watch out for, the specific details and liability are your responsibility.

Examine commercial products and try to reconstruct and understand their
engineering decisions, including the dimensions, stresses and factor of
safety. I did before designing my bucket loader. A textbook on Statics helps
enormously. If that's too much effort, at least film the project for reality
TV.
