Fixin' to put together my gantry crane. I got a couple of beams to choose from for the main beam. My hoist weighs about 300# (electric chainfall), and is on a trolley. Max load I plan on is 2000#. That should cover anything I do. Call it 2300#.

Beam I want to use is a 10"x22# S shape (tapered flanges). 5-3/4" flange width, web measures .255 (paint and all). Figure it's A36.

Span is 14' between the uprights, but I am coming in on each side with 4x4x1/4 square tube diagonal braces...out 24" and down 24" from the intersection of the crossbeam with the upright, so effective span should be more like 10'.

This is in my personal workshop, not for hire, so no osha or liability to worry about if you give an opinion.

I do have an 8x8x35# I could use...rather use the 10x22 though (less weight up top, fits my trolley, etc).

Any opinions?
 
I use this little tool. called beamboy its free and has common beams in its small db, or you can define others. It can do some simple load calculations where you define the load and brace points. Download it and give it a shot,

Thanks, Mike...finally got a chance to download it and run things thru...lots easier on my brain with this.

Now, all I gotta do is some cutting and welding...and find a crane to stand it up.
