This paper discusses tipping mechanism for high dump level.Theconception of kinematical type-synthesis is deduced from mechanical skeleton,which is the source of idel design,based on neremberg scissors;then transformthe mechanical configuration to a dump-mechanism.Author indicate that thekey of dimension-synthesis and various technical specifications is how to dependupon the lenghth of bars of such mechanism.Otherwise,author proposes the CAD Software for calculation of the data,anddisplay sketch of the scheme in the screen for visual evaluation.
