         6 . The construction machine according to  claim 1 , wherein the support structure is mounted exclusively on the transverse guide, and that the support structure is mounted on the transverse guide exclusively in the working direction in front of the operator's seat. 
     
     
         7 . The construction machine according to  claim 6 , wherein the operator's seat has a seat index point, and that the support structure is mounted on the guide rail such that it can be swiveled about the swivel axis such that the operator's seat can be swiveled between a straight-ahead position and a side position, wherein a vertical plane through the seat index point and the swivel axis in the straight-ahead position and a vertical plane through the seat index point and the swivel axis in the side position form a swivel angle, and wherein the swivel angle is in particular at least up to 40°, preferably at least up to 50° or at least up to 60° or at least up to 70° or at least up to 80° or at least up to 90°. 
     
     
         8 . The construction machine according to  claim 7 , wherein the vertical plane through the seat index point and the swivel axis is oriented parallel to the working direction when the operator's seat is in the straight-ahead position. 
     
     
         9 . The construction machine according to  claim 7 , wherein the transverse guide runs transversely to the working direction and, at its ends spaced apart transversely to the working direction, in each case defines an end position for the operator's seat, wherein the operator's seat, when in one of these end positions and in the straight-ahead position, is arranged such that the seat index point is arranged at the level of the transverse guide in a direction transverse to the working direction, and that in these end positions the operator's seat can be swiveled away from the guide rail about the swivel axis such that the seat index point lies behind the transverse guide in a direction transverse to the working direction. 
     
     
         10 . The construction machine according to  claim 9 , wherein the seat index point of the operator's seat is adjustable transversely to the working direction beyond the outer contour of the construction machine by a distance, the distance being at least 5 cm, preferably at least 10 cm or at least 15 cm or at least 20 cm or at least 25 cm or at least 30 cm.
