Abstract
Scientifically based technical solutions are proposed to increase the efficiency of sampling crab trap rows using wedge-shaped disks. Modeling of extraction processes and stresses in the mainlines with different diameters and design features of the mainline extraction winches was carried out, where it was shown that the modern foreign-made winches used do not take into account the working conditions in the economic zone of Russia. The wear process of a crab-type backbone is described. Recommendations are substantiated for the modernization of line extraction winches by increasing the diameter of the wedge-shaped disk and moving the guide rollers with a cutter, which speeds up the extraction process and reduces line line wear, as well as using four-strand line lines, which will reduce line line wear by an additional 18%.
