Just read that a 1% grade on a 200 foot crane pad can put you 2 feet out of level. Found it in an old NCCCO study guide.

Wow, that's a wild little fact. I remember a crane operator telling me once that even a tiny slope you can barely feel with your feet gets massively amplified by the height. He said they use these precise laser levels to check the pad before setup because eyeballing it just doesn't cut it. Makes you realize how critical that initial leveling really is.

Ever wonder how they level the crane itself?
