I'm curious as to why you went through all that fab to hoist it vertical? I see the guage of metal is thick, but is it that heavy that two people can't simply walk it up? My tower was a hinged 30'er and just two of us walked it up and then the long center mast post was pushed up manually, then pinned in place, to further raise the antennas. A crank-up tower of that guage should be able to be permanently anchored, and then you can climb that small height to install the antennas then raise it. Or am I missing something here?
