Bucket excavator directly to the executive condition of the vulnerable component, so digging bucket bucket type, strength, welding, sheet metal, and so on parameters directly determine the life; our according to the original bucket shaped or customer requirements, using 2D AutoCAD structure design, 3D SolidWorks stress analysis, condition simulation, through the automatic NC flame cutting material, then the CO2 shielded arc welding and ambush welding, an increase of plate thickness, wrap angle of weld and welding anti chain plate mill, using automatic sandblasting, painting equipment to eliminate welding stress, improve the comprehensive quality of products, thereby greatly prolonging the service life of the product
