Furthermore, each eye-bolt connection 21 comprises a fork 24 with two pins 25, each pin 25 having a second eye 26, the fork 25 being arranged on the chassis 12. The holding means 22 is mounted between the two pins 25 of the fork 24 in the connected state of the cable plow 11 and the chassis 12 so that the first eye 23 and the two second eyes 26 form a common through opening 27, as shown in particular in FIG. 2b. Each eye-bolt connection 21 also comprises a bolt 28, the bolt 28 for connecting the chassis 12 and the cable plow 11 being guided into the through opening 27.

(12) FIG. 1 shows that each support 19 has a side adjustment device 29 for adjusting the angle of inclination of the support 19 in relation to a planned direction of travel F. The supports 19 can be moved away from and toward the driver's cab 17 in a plan view by means of the side adjustment device 29. The side adjustment device 29 is hydraulically adjustable, the side adjustment device 29 comprising a hydraulic cylinder which is arranged between the support 19 and the driver's cab 17.

(13) Furthermore, each support 19 has a height adjustment device 30 for adjusting the angle of inclination of the support 19 in relation to the ground surface 31. The height adjustment device 30 is hydraulically adjustable, the height adjustment device 30 comprising a hydraulic cylinder which is arranged between the support 19 and the driver's cab 17.

(14) The driver's cab 17 can be raised by means of the height adjustment devices 30 of the supports 19 relative to the ground surface 31 by a height that is greater than the height of the cable plow 11, so that the driver's cab 17 is movable or moved in order to connect the cable plow 11 and chassis 12 via the cable plow 11. In the embodiment in accordance with FIG. 1, the driver's cab 17 has moved to a height which is greater than the height of the cable plow 11.

(17) FIG. 1 shows that the chassis 12 has a carriage 34 and the cable plow 11 has a carriage mount 35, the carriage 34 being mounted with a precise fit into the carriage mount 35 in order to connect the chassis 12 to the cable plow 11, in that the carriage 34 is being moved or is moved through the chassis 12 into the carriage mount 35. The carriage 34 is preferably arranged at the front of the chassis 12 in an intended direction of travel F.

(18) The carriage 34 of the chassis 12 mounted in the carriage mount 35 of the cable plow 11 positions the cable plow 11 on the chassis in such a way that the holding means 22 of each eye-bolt connection 21 is arranged between the pin 25 of the associated fork 24.

(19) A number of line routing extensions (not shown in the figures) corresponding to the number of laying units 14 of the cable plow 11 can be arranged on the chassis 12, the line routing extensions being adjacent to the line routings 16 of the laying units 14 in a connected state of the chassis 12 and the cable plow 11 so that the line routings 16 are extended by the line routing extensions.

(20) The cable plow system 10 can further comprise one or more towing vehicles (not shown in the figures) for pulling the chassis 12 and the cable plow 11 through the ground.

(21) To connect the chassis 12 and the cable plow 11, the chassis 12 is first moved to a height that is greater than the height of the cable plow 11. The chassis 12 is then moved over the cable plow 11 and connected to the cable plow 11 by means of the coupling device 20. Now the chassis 12 can lift the cable plow 11 and move it to the desired operation site. The chassis 12 can also move the cable plow to a transport vehicle and set it down thereon. The coupling device 20 can then be released again and the cable plow 11 can be moved to the operation site by means of the transport vehicle. At the operation site, the chassis 12 can be quickly and easily reconnected to the cable plow 11 for unloading the cable plow 11. The cable plow 11 can then be unloaded by the transport vehicle by means of the chassis 12. Furthermore, the chassis 12 can set the cable plow 11 in a starting pit before the laying process of the lines 13 begins.
