Abstract

The invention relates to cable skidding installations and can be used in forestry in the development of forests on mountain slopes, in lowland and marshy conditions. The purpose of the invention is to increase the productivity of the installation by mechanically feeding a load hook to the attachment point for a rough load. The cable installation contains a self-propelled chassis 1, carrying a vertical mast 6, with the top 7 of which is pivotally connected to the post 7, mounted with the possibility of rotation of the vertical plane along the self-propelled chassis 1. The supporting cable 4 is attached to the rear support 9 and stocked through the block 10 at the end of the rack 7 , the additional block 11 of the carriage 12, the block 13 at the end of the stand 7 and is wound on its drum. The cable 3 (or return rope) is connected to the load hook 14 of the carriage 12 and through the corner blocks 15, 16 and 17, through block 18 on the rack 7, is wound onto its drum 2. In this case, the winding drum of the carrying cable 4 is located in the alignment with the drum 2, their axes are parallel and are located along the longitudinal axis of the self-propelled chassis 1. 1 Il. sl jz. .l .j- ;.

Description

25

The invention relates to cable skidders and can be used in the forest industry in the development of forests on mountain slopes, in lowland and marshy conditions. five

The purpose of the invention is to increase the productivity of the installation by means of a mechanized unloading of the load hook to the place of attachment of the load.

The drawing shows a schematic diagram of the cable installation (dash-dotted line I shows the transport position of the turntable)

The cable installation contains a self-propelled chassis 1, for example, an MTZ-80 tractor, from whose power take-off shaft (through a reversible gearbox, drive shaft, open gear drive, clutch — conventionally not shown) the torque transmitted to the drum 2 of the winding pulley of the rope 3 and the drum of the winding of the carrier cable 4. The drum of the winding of the carrier rope 4 is located in alignment with the drum 2, their axes are parallel and located along the longitudinal axis of the self-propelled chassis 1 o Both drums are located at the base 5 of the vertical part of the mast 6. From the top in the main part of the mast 6, the rack 7 is pivotally connected in a vertical plane along the self-propelled chassis 1 by means of a hydraulic cylinder 8. The carrier cable 4 is attached to the rear support 9 and stocked through block 10 at the end of the mast 6, additional block 11 of the carriage 12, block 13 on the end of the mast 6 and is wound on its drum (not shown), located along the longitudinal axis of the self-propelled chassis 1. The pivot cable 3 (or return cable) is connected to the load hook 14 of the carriage 12 and through the corner blocks 15, 16 and 17, through block 1B on the mast 6 winding are on a drum 2. Pozi- qi 19 and 20 denote brace the mast 6 and the rear support 9, and 21 - an unloading platform corner blocks are arranged in the order of supplying the load hook 14 to place the load slinging.

The installation works as follows.

In the transport position of the ropes 3

logging area. The ropes 3 and 4 are assembled and stocked (as shown in the drawing) by placing rack 7 in the upright working position. Pull-outs 19 and 20 are placed on the mast 6 and the rear support 9. Rotate the drum 2 to pull the rope 3 onto it, and the drum of the carrier rope 4 is braked and the carriage 12 moves up to the cutting area. To deliver the cargo hook 14 with the carriage 12 to the load attachment point, brake the load-bearing cable 4 smoothly smoothly, and the return cable 3 direct the hook 14 to the Corner unit 15 and hook the load. Next, the carrier cable 4 is wound on its drum, and the traction cable 3 is braked, the load is lifted, moved and becomes along the line of the carrier cable 4. With further winding of the carrier cable 4, the carriage 12c moves downward to the unloading platform 21, where, the load bearing cable 4, the load is lowered onto the unloading platform 21, where it is uncoupled from the hook 14 and the carriage 12 is again moved upwards and to the cutting area. After the entire load at the corner unit 15 has been moved to the unloading platform 21, the corner unit 15 is removed and the load hook 14 will now be supplied to the corner unit 16.
