Crane runway girders are subjected to different loading conditions by its using objects, even if the used cranes are all the same with the rated load and the type. This study was to attempt the classification of overhead travelling cranes according to working condition based on measured stress range histograms. The measured crane runway girders were those of the heavy plate mill yard of iron work, steel fabricater and heat treatment yard of steel bar. The classification method of cranes conformed to the principle of JIS B8821 in which was classified into four groups of I, II, III and IV by combination of two factors of the rate of working hours and rate of loading. The results of classification of cranes in those different works showed that the group of crane in heavy plate mill yard was III, in the steel fabricater was II ,and in the heat treatment yard was II〜III.
