The article gives the energy estimation of the efficiency of work of the main movers of the machines for repair and maintenance of pipelines – wheeled and walking. Discusses a private task of definition of efficiency – efficiency mover, which is the ratio between the thrust and power of resistance movement. For the first time shows the calculated dependence of this parameter for. The results obtained indicate that the newly proposed dependence allows to specify the instantaneous power to be used when milling the frozen ground at 40%, and the average effective capacity of milling by 5%. In addition, this dependence allows us to rationally arrange the cutter relative to slaughter to ensure lower costs of milling, which can be reduced by 5–10 %.
