I got lucky enough to build concrete stave silos as a youth. We built from 12′ in diameter by 50′ high all the way up to 24′ x 80′. On that biggest silo, I did get to help stack staves (6 man crew) and spent the whole job in the air with two other guys.
While finishing the job, once the staves had been stacked we would have to hang extra steel around the silo 45′ into the air and that was done by hanging on the side and attaching and tightening steel with hand ratchets w/ 1 1/4″ openings.
Also once that was done the roof, ladder and pipe had to be hung on the silo. I was the guy who stood in the crow’s nest (a 2’x2′ board) and held the top side of the rood sheets. Then once the roof was finished and cap in place I ran the ladder and pipe. That meant I had to hook j-bolts to the ladder and attach to the steel hoops, then if there was a second or third section of ladder and get it attached. The pipe was all together but would need to have the clamps attached and then both the ladder and pipe would need to be straightened. All of this was done with a safety belt on the side of the silo.
On the four man crews, I worked on the ground and in between hooking staves to stack the silo, on the ground we got all that stuff ready by putting it together all the while hauling staves around the silo to be stacked. Each stave weighed 90#. It was a great job, but I think I was a weekend alcoholic!!!
