The article presents a method of calculating the parameters of the scraper working equipment of a trench excavator that performs critical depth cutting: critical depth for its cutters, number of cutting lines, pitch of cutters, height of scrapers, cutting speed, working speed, length of plowshares of cutters, necessary effort of cutting of soil, power to drive the working equipment and movement, power selection of the base machine. Methodology/approach. To solve these problems, analytical methods were used to study the parameters of multi-scraper excavators that perform critical depth cutting of soils. Findings. The developed technique allows to create energy-efficient working equipment and to determine its critical-depth modes of operation, which make it possible to increase productivity and reduce the energy consumption of multi-scraper chain trench excavators that carry out blocked cutting of soils. Research limitations/implication. The initial data for the calculation are: the width of the cutters, their cutting angle, the maximum depth of the trench, the width of the trench, the physical and mechanical characteristics of the soil. Originality/value. Managed to achieve the prerequisites for reducing the energy intensity of soil development scraper chain excavators based on critical depth cutting of soils.
