Sean, I also have come to that conclusion, at least what you can cover yourself. A crane came to a job once and when I checked out the wedge socket that holds the whole hook shabang to the cable, I saw that the bolt and nut that are part of the fastening system was so loose that I could spin it with my fingers. I think it was grounds for tearing the crane operator's head off. I don't know why, but i didn't say anything, just tightened it myself. No way, Jose.
