Didn't seem to load, but from the title, that's a falling derrick, which
I like. it doesn't have anyone under the tower as it goes up. Unlike the
"walk it up".
I'm sort of OK with a one person "walk it up" because that one person
can jump left or right and control things, but when you get a group
together, and the guy on the right jumps left and the guy on the left
jumps right, it's a recipe for disaster. All it takes is one of the
people stepping in a hole or rock as they're raising it up
That said, a team that has done it a bunch of times together probably is
reasonably safe.. but why not use something like a falling derrick, to
pull from the uphill side.
