Hire a wrecker to do it and be done!!!
building a gantry crane
I'm wanting to build a gantry crane. Needs to be 8' long and 8' high and capable of lifting 5,000 pounds.
The design is simple--two A-frames with an I beam between them and some type of winch.
I need to make sure the thing is tough enough to do what I'm asking--so, what size steel pipe to use?

If people here can help me figure that out, then I'll start considering whether or not it's too much trouble to install wheels or not...
Reason I want a crane is to be able to lift an object that is on a pallet, weighs about 2 tons, and get it on to my trailer. Trailer is 32" off the ground, object to be lifted is approximately 4' tall.
Any help?
Thanks

I just now remembered, we have one sitting in the yard, not sure of the exact dimensions but its going to be heavy duty. If your any where near Nebraska, I'd sell it to you would be cheaper and a lot less time spend on building one.
