Well, I definitely do not plan on jumping onto my own petard; not as crazy as I was growing up. I have a pretty good track record of 'knowing when to hold them, knowing when to fold them; knowing when to walk away'. Sorry, I had to; that damn song has been stuck in my head this morning for some reason.

The Gambler is a favorite.
Concrete is witchy.
It can last from thousands of years or become unstable in a few decades or less depending on many factors.
Fasteners anchored into concrete are complete wild cards, lol load test to determine their integrity
So any ladders, catwalks, structures etc anchored to concrete can be solid or just waiting for that extra 20 pounds of loading to snap loose.
Rarely do you get any warning other than subtle visual clues... if any.
The concrete in the pic looks in good shape.
The fasteners and their anchors may or may not be.
I see a lot of surface rust and the structure has had prolonged/repeated exposures to water and freezing cycles, not good.
Be extremely careful if you attempt to climb it... bug out if not sure! https://www.concre.../concrete-history/
