Wow, I am being reminded of why I don't like car forums... So much to say on such a boring topic. I figured I'd be getting ripped for the alcohol and no PPE in my pictures around grinding, spray paint, and other organic vapors. To each their own, I guess.
For s***s and gigs, here are some "heavy lifting" related pictures from where I work. Picture 1 is a hydraulic shovel during a swing bearing replacement. The "House" is being lifted by screw jacks that double as the jack stand when depressurized via the screw being jammed. The lift is ~160,000lb, or 80k tons. We have done this job 3x in the past 2 years without incident.... although we can experience catastrophic failure of one of the four jacks and still maintain the lift.
At the other end of the spectrum is picture 2; the cert placard on an i-beam trolley we routinely use to pick 1500lb pumps or motors, without incident. Yes, that is 75% of rated capacity.
