FIELD: agriculture.
SUBSTANCE: invention relates to mining combines and can be used during driving of mine workings mines, pits. Tunnelling machine actuator comprises frame, cutting bit, reduction gear, electric motors, boom with reduction gear, arranged with possibility to turn relative to frame along its axis at required angle and fixed relative to frame by means of flange with retainers. Reduction gear has two drive shafts. Reduction gear turn relative to frame is driven by electric motors at boom reducer unfixing relative to frame by means of said retainers.
EFFECT: technical result consists in increase of efficiency of machine due to involvement in process of destruction of second cutting bit.
