description: The research was based on a prototype of an existing excavator that meets modern requirements for the operation of earthmoving and construction machines. A new node model has been developed using the initial data of the actual model and loads by the parametric method. The purpose of the work was to develop a methodology for calculating the box structure of the "arrow-arm" excavator. It was necessary to choose the optimal calculation method, having received an optimized way of designing this component. The method was based on the principle of "from simple to complex", the following were considered: a beam model, a constant crossâsection model and a variable cross-section model. The work consisted of studying the components of the node, numerical and analytical calculations. The development of a new method of calculation and research of this component helps to optimize the design process of typical excavator components. Since the device of modern earthmoving machines is quite universal, using the example of a certain prototype, it is possible to use this technique in the design of such systems. The scale of modern building justifies further developments in this direction and confirms the relevance of the research topic.
