The article devoted to the development of a conceptual desing methodology applied to the working parts of the rope excavator. As notation for the  representation of models used the Unified Modeling Language (UML). Integration method diagram of target classes (DTC), the diagram of class equipment (DCE)and the diagram of functional target classes (DFTC) obtained the model system of management of the work equipment. A result of the conceptual constructing developed a basic invariant of the object architecture, implemented in innovative desing of the woring body.
