Introduction.Questions of the maintenance of territories and road network in winter conditions are directly connected with timely and qualitative clearing of roads and territories of snow. Designing and creation effective milling and rotary snowblowers, which work includes some technological operations on snow cleaning, consist in a correct choice of geometrical and kinematic parameters of basic elements. At a design stage the technique, allowing to carry out a choice of the basic technological

The purpose of this paper is representation of dependences of the basic technological parameters of the milling and rotary snowblowers and sequence of their choosing.Materials and methods. The paper presents analytical equations connecting geometrical and kinematic characteristics of the feeder, the thrower of milling and rotary snowblower from conditions of maintenance of identical productivity. Moreover, the analysis of the received equations and dependences by choice milling and rotary snowblower parameters is presented. Sequences of the basic geometrical and kinematic parameters' influence on each other are revealed.Results.As a result, the comparative estimation of the offered and existing equations is made. The character of dependence of angular speed of the throwing device rotation on translational speed of the milling and rotary snowblower and width of the rotor blade is established. On the basis of the received dependences the algorithm of the basic technological parameters' choice on the milling and rotary snowblowers, proceeding from the minimization condition of the initial parameters' task are considered.Discussion and conclusion. The presented dependences allow to spend effectively outline designing of new constructions of milling and rotary snowblowers and to carry out optimisation of existing models of milling and rotary snowblowers.
