The research devoted to the kinematic mechanism for turning rope of ladle excavator, in the article considered the part of the trajectory of the work process: this process make the turning of the grip relatively to the arrow with the same time turning ladle relatively to the grip. The ladle turning is made because of additional kinematic connection between the ladle and grip and / jr the arrow and implementing internal forces due to the mutual position of the corresponding arrow and grip.

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.
