      <abstract xml:lang="ru">
        <p>В предлагаемой статье приводятся результаты исследований взаимодействия сил при работе скрепера в период зачерпывания материала и устанавливаются основные технические параметры канатных скреперов. В качестве исходной, характеризующей процесс копания грунтов (или процесс зачерпывания насыпных материалов) ковшами землеройных машин, принимаем известную формулу Н. Г Домбровского (см. статью).</p>

        <p>The proposed article presents the results of research on the interaction of forces during the operation of the scraper during the period of scooping the material and establishes the main technical parameters of rope scrapers. As an initial, characterizing the process of digging of soils (or the process of scooping of bulk materials) by buckets of earthmoving machines, we take the well-known formula of N. G. Dombrovsky (see the article).</p>
