Abstract—An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations, such as digging, ground leveling, carrying loads, dumping loads and straight traction. Normally backhoe excavators are working under worst working conditions. Due to severe working conditions, excavator parts are subjected to high loads and must work reliably under unpredictable working conditions. Thus, it is necessary for the designers to provide not only a equipment of maximum reliability but also of minimum weight and cost, keeping design safe under all loading conditions. The force analysis and strength analysis are important steps in the design of excavator parts. Finite Element Analysis (FEA) is the most powerful technique used to evaluate strength of the structures working under high loads. This paper focuses on the solid modeling of the mini hydraulic backhoe excavator intended for light duty excavation task and its FE analysis for strength evaluation. It also includes the effect of the welding on the developed stresses in backhoe excavator parts.
