The object of the study: the process of soil development by the chain working body of a trench excavator of continuous action; the working process of planetary gearboxes, which are used in drives of working bodies and mechanisms for moving road construction machines; the process of destruction of structural materials during the formation of cracks as a result of increasing loads. The value of the coefficient of dynamism in the power transmission of the earthmoving machine in the resonant mode and in the non-resonant mode was established; the confidence interval of the mathematical expectation of the maximum values of the load distribution unevenness coefficient between satellites was determined experimentally; recommendations have been developed to remove or stop the occurrence of bifurcation points in the details of machine mechanisms.
