4. Создание новой конструкции исполнительного органа

Для снижения большой динамической нагружённости отстающего шнека в новой конструкции в кутковой и забойной части установленны резца типа РО 65, потому как они имеют относительно невысокие показатели неравномерности нагрузок на исполнительные органы при работе, минимальный расход энергии при выемке и обеспечивают минимальную потребляемую мощность машины [1. стр. 46].
