Abstract

Over head crane is one of the essential industrial equipments for material handling job. In recent years a little attention has been paid to optimal design of heavy over head cranes. The motive might be, but not limited to the availability of prevailing FEM, DIN, ISO, CMAA, BS, Korea and now KS standards for the design of cranes. Most of the crane manufacturers have standardized the single dimensioned box section for multiple spans and duties of crane bridges for manufacturing simplicity. Owing to the recent upward trend in the price of structural materials not to mention the demanding dimensions of heavy duty crane box girders, utilization of modern design optimization tools is inevitable. Optimal design of over head crane is an important factor on the saving of a material and reduction of the manufacture cost in the economic aspect. A lightweight optimized design is the essential subject as to the industrial crane. This is because of fatigue strength and on functional side has many advantages. Therefore, the over head crane girder wish reduced a material and satisfied the buckling strength and fatigue strength of the design standards through the optimized design was studied by structural analysis by using CATIA V5. The main results obtained from this analysis one as follows.
