FIELD: mining and construction, particularly construction machines, namely drilling rigs characterized by means for land transport, for example skid mounting or wheel mounting.
SUBSTANCE: construction machine comprises chassis, pole member and rotary device having hinged connection. Pole member is installed on chassis and may rotate about hinged connection in direction transversal to longitudinal chassis plane. Hinged connection is attached to pole member in area spaced from pole member base. To urge pole member into rotation device comprises at least one linear rotation drive, particularly hydraulic rotation cylinder pivotally connected to pole member at pole member base by the first cylinder side and pivotally connected to chassis by another side thereof. Linear rotation drive is substantially parallel to pole member.
EFFECT: increased structural reliability.
