Calculate Tractor Boom Load Capacity
Budget: $30 – $250 USD
I have built several tractor-mounted boom extensions and now I want solid, engineer-backed numbers on exactly how much weight each point along the boom can safely handle. The boom is welded from a 3/8" side-steer plate and a 2-1/2" × 2-1/2" × 3/16" square tube. From the plate it runs straight for 10 ft, then kicks up at a 30° angle and continues another 2 ft, giving a total length of 11 ft 10 in.
Its primary job is lifting pole-barn trusses, so the working load will sit in the 500–1,000 lb range. I don’t have to satisfy OSHA, ISO, or any other formal standard, but I do want a clear, defensible safety factor.
What I need from you is a straightforward structural analysis—hand calculations, FEA, or a mix—that tells me:
• Maximum safe load at the hook point and at 1-ft increments back toward the tractor
• The controlling failure mode (yield, buckling, weld shear, etc.) and calculated safety factor
• Any quick-hit design adjustments that would increase capacity without major re-fabrication
Please keep the math transparent enough that I can follow it, and flag any assumptions you make about material grades or weld strength so I can confirm they match what I used. A concise PDF report is perfect; native files from SolidWorks, Fusion 360, or ANSYS are a bonus but not mandatory.
