Liebherr 295000 hook failure

[Findork]

New guy here don't shoot. About two years ago liebherr 295000 hook broke. Now crane has been repaired. Crane hook looks bit different. The nut is a lot bigger than before.

My guess is that bearing broke and shockload broke the stem. And now maybe bearing is bigger. The old design hook bearing is over the dynamic load chart.
