Description

one

The invention relates to the logging industry and can be used for the development of cutting areas with a low carrying capacity of soils after the felling of trees with aggregate machines.

The purpose of the invention is to increase the reliability of the installation.

On; FIG. 1 schematically shows a mobile cable car in FIG. 2 of the logging carriage; fig.Z - the same, with the cable-system.

Cableway installation with a toit from a self-propelled winch 1, a rear mobile support 2, a skid carriage 3, a carrying rope 4 stored in it and a go-supporting rope 5. The mast 6 of the rear mobile support is provided with an emphasis 7, made with slot 8, into which the skid has been passed supporting cable 4. The stop is rigidly connected to the bracket 9 of the movable unit 10.

The logging carriage is equipped with a self-disengaging hook 11 and a conic 12 pivotally mounted on an axis 13 in a vertical plane and made in the form of an arc with a groove 14, the ends 15 of which have blocks 15 that interact with the assembled cable 16 in the process of unlocking the lug 17 from the slot 18 and skidding packs of trees 19

The cable installation works as follows.

After installing the self-propelled winch 1, the rear movable support 2 and the installation of the cable system, the logging carriage 3 with a fixed leg .17 in the slot 18 and freely suspended rope 16, previously passed through the groove 14 of one end of the conic 12, is fed cutting area.

In order to lift the carriage 3 in the process of lifting a pack of trees did not move and was in one place, the operator of the self-propelled winch 1 carrying cable 4 for the bracket 9 pushes the mobile unit 10 through the slot 8 to the stop 7 of the mast 6 of the rear mobile support 2. After installation skid carriage 3 over

choker pushes a collection rope 16 under a bundle of trees 19 (formed by a pile-packing machine or another machine) with a pack of trees, then through the groove 14 of the other end of conic 12 and puts a loop of assembly rope 16 on a self-disengaging hook 11. After that, the choker clears the lug 17 from slot 18 and commands the operator of the self-propelled winch 1 to push the packs of trees 19 towards the conic arc 12. The presence of blocks 15 at the ends of the conic arc 12 and. its pivotal suspension on the axis 13 allows to pull a pack of trees, not only from under the ropes, but also from the side. After pushing the pack of trees 19 to the conic 12 arc, the operator of the self-propelled winch 1 moves the skid carriage 3 with wood to the storage area. In the process of wood hauling, so that the vertical load from the load is evenly distributed to the carrier and heavy duty branches of the cable system, the mobile unit 10 is freed from the stop 7 by loosening the supporting cable 4. Adjusting the tension (weakening) of the entire cable system. The wood skidding is performed by a go-carrying rope 5. At the place of storage of wood, the logging carriage 3 stops, then the bracket 9 of the movable block I10 is pulled to the stop 7, then the skidder carriage 3 is moved to the side The logging area until the bobka 17 is fixed in the nest 18. Then the logging carriage 3 moves towards the self-propelled winch 1 until the collecting rope 16 is loosened. Simultaneously with the weakening of the last loop, the self-locking jib 1ms is automatically thrown out with a hook 11. Subsequently, the logging carriage 3 moves to the cutting area, this moment, the collecting rope 16 is pulled out of the groove 14 of the second end of the conic 12 and from under the bundle of trees 19. In this sequence, the wood skidding cycle is repeated.
