Construction of buildings and structures is a complex process, one of the components of which are the processing of digging. The cost structure constructed earthworks, depending on the types of buildings and structures, ranging from three to sixty percent. Currently, excavation work on 98% mechanized. Machines for the production of excavation, are one of the main vehicles by which the comprehensive mechanization of construction. Equipment construction vehicle with high, fast replacement of obsolete equipment with new, highly productive - one of the main ways of increasing the efficiency of excavation in construction. Intensification excavation mainly ensured by improving the organizational and technological measures to ensure efficient use of earthmoving equipment fleet. The current structure of the fleet, each of which can perform only one operation of the production cycle, resulting in the fact that for the implementation of the entire set of works on creation of earthworks necessary to form a set of machines capable to realize them. An alternative is to use a set of machines earth-moving equipment, multi-purpose equipped with 5-10 kinds of changeable working equipment with 20-40 working bodies, which provides all kinds of earthworks single machine. The purpose of the article. Develop a mechanism for technical and economic assessment of the effectiveness of the set of specialized earth-moving machines as compared to earth-moving machines, multi-purpose allows, under specified production parameters, to establish the limits of their effective application. To determine the efficiency of each unit of the considered earth-moving equipment, and further, to form a rational set of machines that can run on time given the amount of work at minimum cost. Conclusions. Systematic approach to the design of complete production process of digging it possible to establish the relationship between technology and feasibility pokzaatelyami characterizing zemlerony machine and the amount of work they do. The resulting dependence of the volume of excavation and earthmoving equipment performance provided the opportunity to establish the boundaries of efficiency, multi-purpose machines.
