Abstract
Double box girder overhead cranes are used for heavy duty
applications of the industry. Steel price in recent trend is going upwards, that
clearly demanding consumption of steel should be minimized to lower the
cost of crane. In this research a detailed parametric design optimization of the
main girder of box type is performed for a 10Ton capacity and 23m long
span crane, after its basic design using available design rules. In the initial
phase of the study, conventional design calculations proposed by Indian
Standard Rules were performed. Indian standards were used in this work
because of its availability and clearness rather than that the compared
previous works are using it. The crane design was modeled on solid works,
loads and boundary conditions were applied to the solid model, then material
was assigned to the solid model. Finite Element meshes were generated from
the solid model after a comparison of the finite element analysis, and the
conventional calculations stress, deflection, safety and camber are manually
calculated in order not to exceed its allowable values. After that, a
comparison between results of different sections was held so that the
optimum design of minimum weight and cost obtained using decision matrix
technique. The analysis was found to give the most realistic results. The
researcher analyzed the content of the computer aided design course Through
the design of overhead crane, a list of proposed concepts and skills for the
computer aided design, planning for the proposed course and proposed units
