Cranes and their crane runway girder are essential components of various industrial operations and other segments. Each crane and its crane runway girder form a mechanical structural system of material handling. Although the equipment is widely used in industrial buildings, there are very few papers and researches in the sizing phase of beams. In order to assist professionals and students in the area of steel structures to carry out the verification of the dimensioning of the crane runway girder with bracing between supports, this paper presents the following criteria of the project according to NBR 8800 (ABNT, 2008). The objectives of this very research include the procedure for determining project loading demand and project resistances, a verification of the ultimate limit state and the serviceability limit state, localized and fatigue strength checks, and the design of stiffeners welded to the web of the profile of the crane runway beams. In the end, a spreadsheet was developed for didactic and academic purposes through Excel, a commercial applet (Microsoft Corporation), with a calculation methodology addressed. For a calibration of the applet, four examples among the specific literature were considered, beware of this, the concept of crane runway girder dimensioned by NBR 8800 (ABNT, 2008) was also evaluated.
