Without seeing what it is you are talking about, and with the understanding
that I am not an expert at anything in the world, it seems that a couple of
2.5" pipes, 20 feet in length, are not going to hold much of anything,
before deflecting and turning into a pretzel.
Raising a boom is never a problem, assuming the lift point is above the
pivot point, even by a few inches. I have often marvelled at the very large
construction cranes that are transported into a city on flatbed trailers.
When they arrive and are assembled horizontally along the street, erecting
them is a quick job, because the hoisting cables are just a little higher
than the boom itself, and our friend Mr. Leverage is at work..
