Actually if you look at the whole of the crane you see several others of the poles with that stuff on it. I don't think it's human "bits-N-pieces" of meaty stuff, I think it's old worn off paint, like an orange rust-proofing paint. Mystery remains
Totally agree,on my phone the pic was small and looked like human parts.now looking on a regular screen,its chipped paint.
Now I'm completely stumped.
