The invention claimed is: 1. An undercarriage, preferably for a crawler-mounted crane, comprising a crawler track (14) which runs on a crawler carrier (12) and includes base plates (16) articulately connected to one another, with cams (18) being formed on the base plates (16) which laterally center the crawler track (14) under rollers (22), holding plates (26) mounted upon the base plates (16) of the crawler tracks (14), and two metal guide sheets (28) arranged to extend substantially over the length of the crawler carrier (12), and engage said holding plates (26), being laterally mounted upon a lower carriage of the crawler carrier (12) to extend therefrom and into a gap (30) defined by the respective holding plates (26) between the base plates (16) and holding plates (26). 2. An undercarriage, preferably for a crawler-mounted crane, comprising a crawler track which runs on a crawler carrier and which has base plates articulately connected to one another, with cams being formed on the base plates which laterally center the crawler track under the rollers, wherein two metal guide sheets which extend substantially over the length of the crawler carrier and which are engaged behind by holding plates arranged at the base plates of the crawler tracks are laterally arranged at the lower carriage of the crawler carrier, and screws bent at right angles are inserted into and held in holes molded at the upper side of the base plates and fix the holding plates on the base plate. 3. An undercarriage in accordance with claim 2, wherein two screws bent at right angles are connected to one another via a transverse web, which screws inserted into the base plates are supported on it. 4. An undercarriage in accordance with claim 1, wherein the holding plates are made as cast parts. 5. An undercarriage in accordance with claim 1, wherein the holding plates are made in trapezoidal form. 6. A crawler track for an undercarriage in accordance with claim 1. 7. A crawler-mounted crane having an undercarriage in accordance with claim 1. 8. An undercarriage in accordance with claim 3, wherein the holding plates are made as cast parts. 9. An undercarriage in accordance with claim 2, wherein the holding plates are made as cast parts. 10. An undercarriage in accordance with claim 9, wherein the holding plates are made in trapezoidal form. 11. An undercarriage in accordance with claim 2, wherein the holding plates are made in trapezoidal form. 12. An undercarriage in accordance with claim 3, wherein the holding plates are made in trapezoidal form. 13. An undercarriage in accordance with claim 4, wherein the holding plates are made in trapezoidal form. 14. An undercarriage in accordance with claim 8, wherein the holding plates are made in trapezoidal form. 15. An undercarriage in accordance with claim 1, comprising two said holding plates (26) latterally mounted upon a respective base plate (16), each said holding plate (26) arranged to receive a respective metal guide sheet (28) protruding into the respective gap (30) defined between the holding plate (26) and base plate (16). 16. An undercarriage in accordance with claim 15, wherein said respective gaps (30) are lower than height of the cams (18) on the base plates (16). 17. An undercarriage in accordance with claim 1, wherein said gap (30) is lower than height of the cams (18) on the base plates (16). 18. An undercarriage in accordance with claim 17, wherein said gap (30) is defined between said holding plates (26) and base plates (16) in a vertical direction. 19. An undercarriage in accordance with claim 1, wherein said gap (30) is defined between said holding plates (26) and base plates (16) in a vertical direction. 20. An undercarriage in accordance with claim 15, wherein said gaps (30) are defined between said holding plates (26) and base plates (16) in a vertical direction. 21. An undercarriage in accordance with claim 16, wherein said gaps (30) are defined between said holding plates (26) and base plates (16) in a vertical direction.
