well to elaborate , my crew was in a customers plant repairing the
threaded platen holes on a 3300 ton injection molding press{ read pretty
big] and the companies die setters were moving a 35 ton ford trim
molding die across the aisle to another area , did not have anything to
do with our guys or the machine we were working on at the time . I just
happened to be doing a little proactive pocket management while watching
the thing move.

their first error was they had the die hanging at an odd angle using
unequal length chains to the four corners from the main hook .

second problem was this plant has a mix of American and metric dies

and a mix of American and metric lifting eye bolts , you know the
really fancy swiveling kind .

wrong bolt , wrong hole , load broke free on one end , swung to vertical
and yanked the whole dam crane down on the floor , i can still close my
eyes and see it , then i have to pee real bad !!!

nobody was hurt real bad , but it took 12 riggers to clean the mess up
and put the crane back up , the carriage was a total loss , replaced it
outright
