Применение трубопроводного транспорта для перемещения углеводородного сырья, нефтепродуктов является основной стратегической системой России с огромным объемом грузооборота. Доля трубопроводного транспорта в грузообороте транспортной системы России составляет свыше 48%. Проведение сервисных работ трубопроводной системы невозможно без использования средств механизации и специального оборудования. Так, для восстановления ее работоспособного состояния используют различные варианты комплектов машин.Реализация методики. В результате проведенных исследований подобран комплект машин для выполнения технологических операций капитального ремонта участка стального магистрального трубопровода. Рассчитаны основные технико-экономические показатели, с учетом которых обоснована эффективность и целесообразность использования комплекта машин.Результаты. Определена экономическая эффективность комплекта ремонтно-строительной колонны, включающей гидравлический экскаватор с разработанным фрезерным рабочим оборудованием, новизна которого подтверждена патентами на полезную модель РФ.Обсуждение и заключение. Направлениями дальнейших исследований является расчет и обоснование необходимых режимных параметров для внедрения в эксплуатацию фрезерного рабочего оборудования гидравлического экскаватора.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The use of pipeline transport for the movement of hydrocarbons and petroleum products is the main strategic system of Russia with a huge volume of cargo turnover. The share of pipeline transport in the freight turnover of the Russian transport system is over 48 %. Maintenance of the pipeline system is impossible without the use of mechanization and special equipment. So, to restore its working condition, various options for sets of machines are used.Implementation of the methodology. As a result of the research carried out, a set of machines was selected for performing the technological operations of the overhaul of a section of the steel main pipeline. The main technical and economic indicators are calculated, taking into account the efficiency and expediency of using a set of machines.Results. The economic efficiency of a set of machines, including a hydraulic excavator with a developed milling working equipment, the novelty of which is confirmed by patents for a useful model of the Russian Federation, has been determined.Discussion and conclusions. The directions of further research are the calculation and substantiation of the necessary operating parameters for the introduction into operation of the milling working equipment of a hydraulic excavator.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экскаватор гидравлический</kwd><kwd>оборудование рабочее</kwd><kwd>фреза роторная</kwd><kwd>трубопровод</kwd><kwd>ремонт</kwd><kwd>подкоп</kwd><kwd>эффективность экономическая</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydraulic excavator</kwd><kwd>working equipment</kwd><kwd>rotary cutter</kwd><kwd>pipeline</kwd><kwd>repair</kwd><kwd>digging</kwd><kwd>economic efficiency</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Аладинский В.В., Малков А.Г., Ушаков A.B.
