Crane skewing analysis according to standards and according to a dynamic model

Bridge crane skewing analysis is needed for proper bridge crane design. Hannover dealt with the skewing of the bridge crane on a theoretical and experimental level. The results of his work are now included in the design standards for the design of bridge cranes and crane runway. The Hanover skewing analysis assumes two basic assumptions, and that is the uniform constant speed of the crane and the perfect rigidity of the crane structure. The author of this article created a dynamic model of a bridge crane, which solves the movement of a bridge crane in general as a dynamic task. It includes, among other things, considering the bridge crane as a flexible system and considering the uneven movement of the crane. This article deals with the comparison of both models for a specific selected crane.
