Computational Model for Calculation Horizontal Forces on Crane Runway

During a motion of an overhead bridge crane horizontal forces between wheels of the crane and the crane runway occur. These forces can be caused by skewing, acceleration or braking of the crane. There are several procedures for determination of these forces. These procedures can be found in professional literature and also in present standards for check and designing of crane structures. However, when there is made a comparison of computational models presented in the literature and present standards, it turns out that the computational models are different even if they describe the same physical situation – for example skewing of the crane or the acceleration or braking of the crane. The aim of this paper is to create computational model which would describe real behaviour of the crane during its motion on the crane runway and which would also enable to calculate the horizontal transverse forces between the crane wheels and the crane runway. This model will be created by modifying of the model already created by another author by taking account influences affecting the crane motion on the crane runway
