This is kind of a long shot, but is anyone in the market for an adjustable-height 10' span gantry crane? Reason I'm asking is because I want to build one for myself, but the steel supply places I've found only sell full lengths, meaning I'll have enough steel to produce two gantry cranes if I buy new. Would be looking to split cost of the steel, which looks like it's going to be around $1900 total.
I am using plans from this pirate thread, calcs suggest 4.5t rating with a factor of safety of ~3. I've rendered in sketchup as well.
If you're interested, reach out to me! Looking to build soon, intend to use it to break down a parts truck.

Person in the render is 5'10". This is full height of the gantry crane, a little bit over 11' depending on the casters used.
