A professional engineer inspects the crane with non-destructive methods (checking welds, wire ropes, etc.) before it's erected and then it gets inspected again after it's erected. I imagine if the block is down there might be a problem with the wire ropes, especially if it's an old crane. Maybe something got messed up when they reeved the wire rope and now they gotta put on new rope.
Interesting. I wonder to what extent the inspection goes for each set-up of the crane. I question if each and every weld is inspected, and if so, what NDT is used? UT, dye pen., or??
