Mechanical Failure Analysis of a Rake Unloading System using FTA and FMECA

Iron and Steel industries, raw materials are mostly transported, through the railway rakes. The railway provides some stipulated free time, for unloading the rakes and charges a penalty for the delay beyond the free time. This penalty charge increases the cost of the final products. This paper discusses the mechanical failure problem, which is the major cause of the delay in the unloading process, using Fault Tree Analysis (FTA) and Failure Mode Effect and Criticality Analysis (FMECA), to find the critical component of the failure, which helps the management to minimize the breakdowns.
