FIELD OF THE INVENTION The invention relates to the timber and woodworking industry, in particular to the hauling devices of logging machines, intended for cutting fallen trees.

The aim of the invention is to increase the reliability of operation of the traction device of the device.

FIG. 1 shows a schematic drawing of a pulling device as part of a delimbing machine; FIG. 2 is a view A of FIG. i; in fig. 3 - the same, option.

A logging machine pulling device 1 (for example, a delimbing machine) comprises a carriage 3 moving along the guiding beams 2 with a trolley 3 with hooks A, controlled by the branches of the worker 5 and the idling 6 of the carriage 7 moving the carriage 7 mounted on it. The ends of the traction branches 7 are kinematically connected to a trolley over shoulder 8 of one of the grips 4

with another capture by the synchronization mechanism, which is implemented, for example, in the input of link 9 or the gear sector 10. Kinematic connection

the branches of his 5 and idle 6 strokes of the traction body 7 with the trolley 3 are made in the 3-hell

the last lever of the first 1 I or second 12 kind, pivotally connected by a thrust 13 with a shoulder B of the grip 4. At the same time, the axis of connection of the thrust 13 with the lever 1i of the first kind is placed between the axis of its rotation and the end of the connection of the lever - 40 through the connecting link 14, and the corresponding axis of the connecting rod 13 with the lever 12 of the second kind is placed at the free end of the lever 12, p from the opposite end, connected to the branches of the working and idling courses of the traction body 7. The end of the lever 1 or 12, connected to the branches of the working and idling t Body, can be made in the form of a two-strand sector 15 with a radius approximately equal to the distance from the axis of rotation of the lever on the trolley to the axial axis of symmetry of the guiding beams.

The device works as follows.

The operator turns on the drive of the pushing mechanism in the working direction.

branch tension occurs | 5, the stroke by which the lever 11 (or 12) is rotated counterclockwise is moved. t ha 13, turning the shoulder 8, and with it the grip 4. The second grip 4 is rotated by means of a fur. low 9 (or 10) sync. When this occurs, the closure of the grips on the treated tree. Upon further tension of the branch 5 of the working stroke, the cart 3 moves along the guides 2 and the tree is pulled through the delimbing machine organ, as a result of which the branches are trimmed. When the idling branch 6 is tensioned, the grippers 4 are opened and the processing tree is released, and the cart 3 returns to its original position and the cycle repeats.

At the same time, within the bogie, the branches of the worker.
