I inferred the behavior of the cranes of Kobe Port at the Hyougo-Ken-Nanbu Earthquake from their damages. I guess the cranes have acted rocking motion along the cross direction of the rails from the foot-print etc. And the most of cranes' span were widened by widening of rails' span, but some of cranes' became narrow. I estimated its cause. And also I examinated the influence of the crane anchor to the damages.
