Abstract: Specifics of functioning for the drives of main (lifting and thrusting) mech-anisms in an open-pit excavator were determined for their joint action during the process of excavation. It was shown that the operation forms a two-crank lever-age transmission mechanism (connecting the main mechanisms and the excavator bucket) and a common transmission mechanism of the drives (consisting of the main mechanisms and the leverage). It was also established that an initial link of the common transmission mechanism would be a stick-bucket link whose co-ordinates determine positions of every other link in the mechanism in relation to the stand (a boom). Dependencies were derived for finding kinematic transfer functions of the leverage, that is relations between lifting and thrusting velocities and an excavation velocity when the bucket (its cutting edge) is moved along a given trajectory in the process of pit development. The results of the research could be used for the purposes of designing a control system for the main drives of an excavator. © Published under licence by IOP Publishing Ltd.
