FIELD: forestry; machine building.
SUBSTANCE: invention relates to logging machines, namely to hydraulic systems of forest machines, for example forwarders. Logging machine contains a hinged-articulated frame, consisting of a motor half-frame with a cab mounted on it, behind which the hydraulic tank is located, and a technological half-frame on which the working equipment with hydraulic control drive is installed and a freight platform with racks for transportation of assortments. Hydraulic actuator for the control of the working equipment contains a hydraulic distributor, which is located in a niche inside the column directly under the manipulator with the ability to provide access for its maintenance and adjustments. In the column, there is an opening opposite the hydraulic tank, through which the high pressure sleeves pass, the lateral edges of which are made with overlays.
EFFECT: increase in the reliability of the operation of the hydraulic drive for controlling the working equipment of the logging machine and an increase in the service life of the high-pressure hoses.
