The dipper is one of basic parts for electric rope shovel ,the performance ,shape and geometrical parameters of dipper are reasonable or not directly affects the digging resistance and coefficient .According to the mining performance requirements ,the shape and geometry parameters of dipper are determined ;Through the analysis of the mechanical properties of dipper ,the body of dipper is simplified to a simply supported overhanging beam .The relevant hinge point distances at the directions of dipper width and length are respectively obtained ,and compared with the results coming from practical calculation ;By use of impact theory ,the reasonable impact point is put forward ,to make the force on the dipper bushing bearing minimized .This work may provide effective help for preliminary design of dipper .
