TSSA does elevators and roller coasters (and other things) but I don't think they inspect and certify cranes. 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.
