  • Patent number: 11060259
    Abstract: A mobile device for the underground laying of a flexible line, a cable, a cable-pulling empty pipe or fluid transport tube. A front vehicle has a rear support frame, a lateral ejection unit, a milling unit with a milling wheel and a drag formwork or cable laying unit following the wheel. The milling unit is connected to the front vehicle for lateral pivoting up to ±25°, in particular up to ±20°, is laterally offset towards the outside with respect to the front vehicle, and can be positioned to laterally protrude over the contour of the front vehicle, by a primary articulation or a swivel joint on the lateral ejection unit having a substantially vertical axis of rotation. The drag formwork, cable laying and cable introducing unit follows the milling unit and the cable introducing unit are also laterally pivotable about a second swivel joint.
