Lifting equipment’s have a wide range of use in all commercial and industrial area from small to large. The machine that enables the lifting of a substance and transporting it from one place to another under conditions where human power is not enough is called a crane. Overhead cranes are frequently used in workshops and construction sites. Overhead cranes are a bridge construction that travels between two runway girders that form the high-rise crane running path. Initial investment cost in facilities is very important. High-weight equipment, such as bridge cranes, must both work efficiently without any security weakness and be of optimum weight. For this, optimum system design should be made. The aim of this study is to optimize the cross-section values of the girder in order to bring the unit weight to the most reasonable level. In this study, analytical calculations based on FEM and DIN standards were used for calculations. Practical Design Optimization steps were determined for optimization by using analytical solutions. Optimization has been performed on the cross sectional values of girders so as to reduce the unit weight which is the main cause of production costs. Results indicate that the unit weight of girder decreased 32.16% after comprehensive optimization process was performed.
