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 fordifferent designs of propellers. Defined boundary parameters movers and their relationship to each other, providing not damage the pipeline when creating traction. The analysis of surfaces movement cleaning machines for repair and maintenance of pipelines. It is shown that the maximum efficiency will have mover interacts with the completely purified steel surface of the pipe. The calculation for this case the movement of the machine, and identified the conditions for the rational use of any type of propulsion.
