Annotation:
In the article the results of studies on the productivity of dragline excavators applied for overburden loading into transport vehicle are given. The analytical dependence of the dragline performance on the width of cut during loading into heavy dump trucks is presented. The influence of this parameter on change of the angle of rotation of the excavator to unload, the time spent on its movement, making slopes ledges, etc. is investigated in detail.
