✦ Synopsis

Intrinsic fatigue curves are applied to a fatigue life prediction problem of the metalwork of a travelling gantry crane[ A crane\ used in the forest industry\ was studied in working conditions at a log yard\ and strain measurements were made[ For the calculations of the number of loading cycles\ the rain~ow cycle counting technique is used[ The operations of a sample of such cranes were observed for a year for the average number of operation cycles to be obtained[ The fatigue failure analysis has shown that failures of some elements are systematic in nature and cannot be explained by random causes[
