Introduction.Construction in Kazakhstan is one of the leading sectors that has a significant impact on the development of a large number of related industries of the Republic of Kazakhstan. No construction is complete without road construction equipment. Despite the positive developments in the industry including the park of the main construction machinery, things are still more difficult than that. The acquisition of new machine base, with working bodies’ equipment is very expensive. It is economically expedient to develop hinged working bodies on the basic machines existing in Kazakhstan enterprises. Materials and methods.According to the demonstrated problem, the article considers the method of morphological analysis to identify new types of working bodies of digging machines. Moreover, the main classification features of the working bodies of excavating machines are determined in the research and the number of trajectories of the working element’s movement is established. Results.The constructed morphological tree is presented and as a result of such method, the 484 possible and existing designs of working bodies of excavating machines are revealed. A set of conditions for excluding the unacceptable options for hydro mechanical and mechanical working bodies from the hypothetical working bodies is formulated. Discussion and conclusions. Suspended tunneling equipment could be used for both trenching and well drilling, and such processes are evidenced by the patent for the design.
