The state of loading for cranes is investigated quantitatively and practically as the spectrum factor K_P defined by ISO 4301, using the measured values in the operation of the various cranes. Approximation by the beta distribution, which is advantageous for K_P estimation, can be performed on the basis of the hoisting load distribution. A hoisting load distribution to be used for the design of grab-bucket unloaders is presented as a function of the beta distribution. The estimation procedure of stress range distribution of the crane structure members is also investigated from the viewpoint of design. Since the stress range is determined by the random variables of multivariate functions, the first-order approximation can be a useful method at the design stage.
