Failure of a structural or mechanical component of cranes usually can be associated with materials-related problems and/or design-related, as well as the fabrication-related problems or inadequate structural maintenance. Also, crane components and structure experience a spectrum of stresses while operating. Therefore, about ten percent of material handling high-performance machines failures can be attributed to fatigue failure. In most cases these failures were unexpected and lead to catastrophic consequences. This paper discusses some aspects in failure analysis of cranes, particularly high-performance ones, gives the background for failure analysis and presents some typical examples of failure. The aim of this article is to encourage practitioners in the failure investigation process to look beyond the metallurgical issues and to also examine the loads and stresses.
