I gotta’ tell you ... looking at your ladder ‘crane’ made my stomach hurt ... imagining you climbing up that thing almost made me dizzy. I do not do heights at all! More power to you to be able to handle it & thus get your project done!
We have 11’ ceilings in part of the house including the kitchen. Mom has this huge, decorative clock hanging way up on the wall. Twice a year, when the time changes, I have to bring in a large step ladder, climb up there & get that clock down so we can change the time/battery. The clock is over a bookcase so I have to go up beside the bookcase & lean off the ladder a bit to reach the clock rather than a straight on approach. Getting it back on the hanger, since I can’t actually see anything, is the worst - I found if I take blue painter’s tape & mark on the wall the bottom & left side closest to the ladder, I have better luck because at least I am in the ‘neighborhood’, not moving the large (& getting heavier by the second) clock all over the wall. In the meanwhile, I am close to hyperventilating because I am so high (for me) up on that ladder. I haven’t changed the time on that stinkin’ clock yet this month, keep finding reasons to procrastinate.
I definitely wouldn't do that these days and was very focused and cautious today. I'm a little slender guy so my weight was not an issue.

Fireworks misfire 5-6 years ago. Big boom at ground level is not right. I forgot to flinch I guess.
Ok, I'm just crazy.
But it's so much fun.
