The known technical solutions do not provide reliability during vehicle operation; moreover, they do not provide a stable position due to the possibility of the vehicle overturning when working with large trees, in addition, the location of the cab close to the manipulator impairs the view, not allowing a full turn around its axis.

The problem to be solved by the claimed technical solution is to ensure reliability during the operation of the logging machine.

The problem is solved by the fact that a logging machine, including a self-propelled chassis, containing an articulated bearing system, including a front frame, a rear frame and an articulation unit, front and rear axles, an internal combustion engine located at the rear of the rear frame, a cab with a swing mechanism , a manipulator consisting of a stand, a boom and a working body with a feller delimbing head, the cabin is located on the rear frame with the possibility of full rotation around its axis, and the manipulator is in the middle part of the chassis, while the roll cylinders are additionally installed on the articulated supporting system, one end connected to the rear frame, and the other to the articulation unit.

The set of distinctive features, consisting in the fact that the cab of the forestry machine is located on the rear frame with the possibility of full rotation around its axis, and the manipulator in the middle part of the chassis, while the roll cylinders are additionally installed on the articulated supporting system, one end connected to the rear frame , and the other - with the articulation unit, allows to ensure reliability during operation.

The utility model is illustrated by the following drawings:

fig. 1 - logging machine, general view (rotated in isometric view);

fig. 2 - the same, general side view (isometric).

The forestry machine includes a self-propelled chassis, which contains an articulated supporting system 1, which contains a front frame 2, a rear frame 3, articulated through a joint assembly 4, which rotates the frames relative to each other around the vertical and longitudinal axes. A front tandem axle 5 is rigidly mounted on the front frame 2, and a rear tandem axle 6 is rigidly mounted on the rear frame 3. The chassis also contains an internal combustion engine 7, a cab 8 with a swing mechanism, a manipulator 9, consisting of a rack 10, a boom 11 with a hydraulic cylinder drive 12 and a handle 13, at the end of which there is a working mechanism with a feller-delimbing head 14. At the same time, hydraulic cylinders 15 for turning the frames are installed on the articulated supporting system to rotate the front and rear frames about the vertical axis, and for turning around the longitudinal axis - hydraulic cylinders 16 roll ... Moreover, the hydraulic cylinders 15 for turning the frames at one end are connected to the front frame 2, and the other to the joint 4, and the roll cylinders 16 are connected at one end to the rear frame 3, and the other to the joint 4. The use of 16 roll hydraulic cylinders allows the frame to turn at a large angle, block the roll, providing a more stable position, thereby increasing operational reliability when the forest machine overcomes difficult-to-pass places. In addition, the internal combustion engine 7 is located in the rear part of the rear frame 3, and the cab 8 with a pivot mechanism on the rear frame 3 is fully rotatable around its axis on the pivot device 17. The manipulator 9 is located in the middle part of the chassis and is mounted on the support -turning device 18, which is connected to the swinging table 19, secured through the hydraulic cylinders 20 to the front frame 2.

The simultaneous use of tandem axles on the front frame and rear frame provides equalization of reactions on the wheels, increasing maneuverability and flotation, overcoming hard-to-reach places, as well as the location of the manipulator with the feller delimbing head in the middle part reduces the likelihood of the forest machine tipping over, thereby increasing reliability.

Thus, the proposed technical solution allows to ensure the reliability of the structure during operation by ensuring the stability of the vehicle in difficult-to-pass places.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using previously mastered technologies.

The claimed technical solution was developed as part of the work under the Agreement dated November 22, 2019 No. 075-11-2019-030 between the Ministry of Science and Higher Education of the Russian Federation and Public Joint Stock Company KAMAZ.
