Annotation: The article presents the results of long-term research of grab working bodies for earthworks. The branch of application of grabs for earthworks and the reasons for their insufficiently widespread use are determined. A new method for developing soil with a grapple in a closed power flow «working body – soil array – working body» is proposed. The theoretical substantiation of the efficiency of working processes of a grapple with a screw anchor in the development of strong soils is given. A working design of a grappling bucket with a drive screw anchor was made and tested. The results of field experimental studies of this working body are presented. The increase in the filling coefficient and reduction of the energy intensity of the digging process on solid soils, due to the use of a screw anchor, have been confirmed. It is noted that the parameters of mass and stability of the base machine are not the main determining parameters of the process of digging with a grapple with a screw anchor.
Keywords: grapple, earthwork, strong ground, screw anchor.
