Новый тип рабочего оборудования карьерного экскаватора

Abstract

It is shown that with the increase in the unit capacity of the mining excavators, the ratio between the excavating and excavating functions changes, which is determined by the limited dimensions (length) of the boom. the lever working equipment of a mining excavator has been developed, which provides both an increase in the excavating function due to the increase in the dimensions of the working zone with the constant mass of the excavator, and the neces sary ratio between the excavating and excavating functions of the excavator. © A.P.
