DESIGN AND FABRICATION OF A LIGHT WEIGHT ALUMINIUM GANTRY CRANE

Nowadays mostly in shipbuilding, gantry cranes are needed in many areas. With evolving technology the sizes of the structures are growing too. Generally in the construction of these structures gantry cranes are preferred for lifting heavy loads. In this study Main Component of gantry crane is beam which transfers load to structural member. Gantry crane beam is designed with CREO parametric 2.0. And Analysis is performed with finite element method. The working load acting on the beam is 5000N. In the analysis of the beam construction the self-weight of the beam working loads static and dynamic loads arising due to the crane movement are considered. The beam is modeled as a three dimensional design and the analysis of the construction is performed using finite element method with the help of an analyses program. The analysis is performed for three cases. In the first case the analysis is performed by considering only self-weight of the beam. In the second case the analysis performed under the influence of working load (while two trolleys on the beam are in various positions) and in the third case, both the working loads static and dynamic loads. In this study, the stress values obtained from the analysis are examined and the results obtained from theoretical calculations are compared with the results obtained with the finite element method. As a result, using finite element method in the analysis is appropriate and this method provides great convenience in the calculations..
