Pipe spreader bar for cranes
(OP)
I'm currently an engineering intern at a crane company. We use schedule 40 steel pipes for our spreader bars. I have already rated 4 and 8 inch piping for spreader bars and how much load they could lift at various lengths and with various length slings. I am now faced with rating some homemade adjustable spreader bars that consist of one 2 and 3/4 inch bar inside of a 3 and 1/2 inch bar. I was curious if anyone knew of any software that could simulate this and allow me to see how much they could handle before they failed? I need to look at the pipe expanded from 8 to 12 feet and with slings at 10-50 feet.

Follow the same approach with your new designs.

Whatever computer/pencil result you come up with, I would probably additionally want to see a proof loading as a final check.

In designing items which are critical to the safety of the public (including your workers), it is necessary to use established standards and design methods.

I strongly recommend you NEVER assume load or strength factors for a "below the hook" design using ANY "roadside-leftover-scrap-pipeline" material of ANY capacity!
