3. The crash barrier section according to claim 1 , wherein the at least one traveling gear is pivotably or rotatably mounted.

4. The crash barrier section according to claim 3 , wherein the traveling gear is pivotable or rotatable simultaneously during at least one of extension or retraction.

5. The crash barrier section according to claim 3 , wherein the at least one traveling gear is pivotably or rotatably mounted about vertically oriented height axis.

6. The crash barrier section according to claim 5 , wherein the traveling gear is retractable into the standby position with a direction of travel in a longitudinal direction of the crash barrier section, and in the displacement position a direction of travel in a transverse direction of the crash barrier section is provided.

7. The crash barrier section according to claim 6 , wherein the traveling gear comprises at least two rollers arranged successively in the direction of travel, and an axial spacing of the at least two rollers, at least in the displacement position, is greater than a maximum cross-sectional width of the receptacle.

8. A crash barrier system comprising a plurality of adjustable crash barrier segments which can be connected to one another, at end faces thereof, so as to have high tensile strength,

wherein at least one movable crash barrier segment according to claim 1 , can be inserted between two adjustable crash barrier segments whereby the adjustable crash barrier segments are raisable and movable.

9. The crash barrier system according to claim 8 , wherein a plurality of traveling gears can be controlled sequentially or simultaneously.
