Mobile harbor crane wheel hub fatigue failure

Peer Reviewed Articles


Failure analysis of a mobile harbor crane wheel hub demonstrated that the mechanism of failure was fatigue. The wheel hub was a ductile cast iron component that had been subjected to cyclic loading during a ten-year service period. The fracture surface of the fatigue failure also contained corrosion deposit, suggesting that cracking occurred over a period of time sufficient to allow corrosion of the cracked surfaces. Replacement and alignment of the failed wheel hub is recommended along with inspection of the nonfailed wheel hubs that remain on the crane.
