Who ever rigged this cutoff piece of concrete that is rigged so wrong. Thats about 2-1/2 yrds of concrete = 10.000lbs. The amount of stress on them chains being chocked like that almost horizontal on one side of the choke. Sling angle way past it working load rating
I'm not sure if you realized, but this was done on the other side of planet. The land of where safety precautions and measurements are lacking. Things are ran alot differently over there. What's sketchy AF to us, is an everyday thing for them. I work in a steel plant. Knowing my work's and country's safety regulations and laws, then seeing videos of Chinese steel plants, is literally black and white.
