Machinery failure This
photograph shows an example of an overhead gantry crane failure. Examination
of the crane assembly revealed several tell-tale signs that described
the process in which the crane failed. The primary instigator of the
catastrophic failure was a fatigued weld. The weld involved had cracked
and then completely failed; subsequently, the fractured weld surfaces
were abraded to a smooth finish as shown in the image below.
