Appreciation post: That random OSHA stat I found about crane tip-overs

So I was killing time on break the other day and stumbled on this OSHA page about crane accidents. Turns out like 80% of crane tip-overs happen because the outriggers aren't set right or the ground gives way. I always thought it was mostly overloading or wind but nope, it's the stupid ground. Found this stat buried in some 2022 report and it blew my mind. Has anyone else had a close call with soft ground or bad blocking? I nearly tipped a 50 ton once on a job in Houston because of rain soaked dirt.

Wow, wait - 80% from bad outriggers or ground? That's wild, I figured weather or operator error would be way higher up the list.

Yeah @bettywilson that stat surprised me too when I first saw it. Most people think weather or the operator messing up is the big danger but it's really the setup stuff that gets you. Those outriggers sink into soft ground or the pads give out and suddenly the whole rig tips over before you even lift a load. Weather is a factor but usually it's more about the operator not recognizing when conditions are bad enough to stop. And operator error often comes back to bad habits with the outriggers anyway so it all ties together. Just goes to show how much the boring prep work matters...
