In havy-duty material handling equipment, major concern is optimum utilization of material for equipment construction eithout sacrificing the design parameters. To understand this aspect and also to validate the design, as this kind of equipment are vital part of any manufacturing industry, finite element analysis is one of the best method that can be used extensively. The major advantage is that the equipment need not be manufactured and tested physicall to find out the drawbacks. Instead one can simulate the conditions through finite element analysis to obtain an optimum design, [3]. This paper work provides a modeling of the structural strength of a crane bridge, in operation for 15 years in the continuous casting department of a steel plant. Modeling will be done with the aid of a COSMOS/M software who has a 3-shell type advanced finite element, with three or four nodes per element and six degrees of freedom per node. Such software allows us modeling the current geometry very close to that of the crane bridge. The calculation pattern allows us to analyze the state of stress and deformation of the crane bridge strength structure while under the action of loads in mining stock. This paper work is meant for checking out the limit state of the structure subject to normal operation, which involved the evaluation of its reaction while under working in terms of quantity and quality. In quantitative terms, we have revealed that the structure had reserves of strength; qualitatively speaking it had confirmed the validity of modeling.
