The article analyzes the effectiveness of the use of multifunctional machines when performing work in the field of urban planning and environmental design. It has been established that unification ensures a reduction in the cost of equipment operation and allows to increase the rationality of using the working bodies according to their functional characteristics. The authors evaluated the typical nomenclature rows of quick couplers. It has been revealed that the variety of quick couplers offered by manufacturers does not allow to determine a common design feature, and to use it for unification for various classes of machines. In this regard, the authors take its weight to the mass of the base machine during the unification of standard-size series, as a main parameter. The paper develops a technique for unification of quick couplers. Then, the authors modify the mathematical model for estimating the cost of standard sizes of quick couplers according to the exponents and proportionality coefficients. They propose a parametric unification for 14 rows of the main parameter of the quick coupler. Finally, the paper develops a model for estimating the range of parametric applicability of various quick coupler constructions.
