LOGGING MACHINE Russian patent published in 2011 - IPC A01G23/81 

FIELD: agriculture.

SUBSTANCE: logging machine comprises tracked powered chassis with front and rear lever-centerpoint suspensions, which connect crawler-mounted movers and chassis frame. In front part of chassis, on its frame, the operator's cabin is mounted, as well as bulldoser equipment that rotates in vertical plane, and an external support joined to chassis spars in specified part of chassis, where a hydraulic manipulator is installed with a rotary working head. Axis of rotation of the manipulator column is installed in longitudinal-vertical plane passing through longitudinal axis of chassis symmetry. In the rear part of chassis, behind the operator's cabin, a loading platform is installed for assortments, the longitudinal-vertical plane of symmetry of which passes through the longitudinal axis of chassis. Loading platform comprises a base, vertical side stands, a thrust-end shield. The loading platform is installed on the chassis frame with the possibility of rotation in horizontal plane by means of a rotary facility arranged between spars and the platform base, and the vertical axis of its rotation is located between the axis of levers rotation and axes of beams in the rear lever-centerpoint suspension. The thrust-end shield is arranged in front part of the loading platform.

EFFECT: invention realisation provides for full cycle of lumbering operations on weak soils of wood cutting areas, and for wide spectrum of technological operations of trees felling and processing, while at the same time machine operational reliability and its ergonomic characteristics improve.
