While I sometimes use the 2-step method described above, you can use a
proper mast to anchor the top of the tram line. With back-guying there's
little or no pull on the mast and you can go as big as you want. I've trammed
up full-sized HD 40M beams (250-300#) directly from the mast. It WAS a 4130
mast with 3/8" wall so it was industrial strength and it was back-guyed.
