It has been determined that under the combined action of the main mechanisms (lifting and thrust mechanism) and
implement mechanism, which are part of a gear of a power shovel, the modes of operation of lifting and thrust mechanisms
of engine change significantly. It has been shown that in the process of digging, changing of operating parameters is
conditioned on both shovel drag force (gravitational force of rock passing into the shovel, and friction force) and changing
of the relative position of links of the implement mechanism and, thereafter, arm of force. Values of operating parameters
of the main mechanisms have been determined (speed, lifting and thrust force) depending on the position of a shovel in
operating zone of the excavating machine under constant values of digging resistant force and digging speed. Operating
space of the excavating machine with main mechanisms with accelerated service have been detected under the shovel
shift along the steeply inclined trajectories, parallel to the slope of a bench. The analysis of the degree of the main
mechanisms driving gears interaction under the realization of the given energy-power parameters on the blade of shovel
will make it possible to substantiate the adaptive and self-organizing system of workflow control.
Key words: power shovel; main mechanisms; implement mechanism; engines workflows.
