A locking mechanism is provided for a tarping system having a flexible cover deployable from a roller assembly for covering a container and a mechanism for extending and retracting the cover from the roller assembly. The locking mechanism includes a locking element, such as a taut cable, mounted to the roller assembly and spanning the width of the cover. The locking element is arranged on the roller assembly with a portion of the length of the cover less than the entire length of the cover wound around the locking element. This portion of the cover corresponds to an extended length of the cover. The locking mechanism prevents further advancement of the cover from the roller assembly once the locking mechanism is uncovered when the cover is unwound.

1. A locking mechanism for a cover system covering a container, the cover system having a flexible cover deployable from a roller assembly with a rotatable roller carrying the cover wound thereon and a mechanism for extending and retracting the cover from the roller assembly, the locking mechanism comprising a locking element mounted to the roller assembly for rotation with the roller and spanning a substantial portion of the width of the cover, said element arranged on the roller assembly such that a portion of the length of said cover is wound over said element when the cover is wound onto the roller assembly, wherein the portion of the length is less than the entire length of the cover. 2. The locking mechanism of claim 1, wherein said element is a cable spanning the entire width of the flexible cover. 3. The locking mechanism of claim 1, wherein said locking element is a generally rigid rod spanning the entire width of the flexible cover. 4. The locking mechanism of claim 1, wherein said locking element is removably mounted to the roller assembly. 5. The locking mechanism of claim 1, in which the roller includes hubs at opposite ends thereof rotatable with the roller, wherein said locking element is mounted to each of the hubs to extend across the cover. 6. The locking mechanism of claim 5, wherein said locking element is removably mounted to each of the hubs. 7. The locking mechanism of claim 6, wherein each hub defines an opening through which said locking element is received and including a fastening element configured for fastening said locking element within said opening. 8. The locking mechanism of claim 7, wherein: said hub defines two or more openings through which said locking element may be selectively received; andsaid fastening element is configured for fastening said locking element within a selected opening. 9. The locking mechanism of claim 8, wherein said hub is square-shaped and defines an opening at each corner of the square shape. 10. The locking mechanism of claim 7, wherein said fastening element includes a bore defined in said hub and intersecting said opening, and a set screw configured for engagement with said bore, said set screw arranged to bear against said locking element to fasten said locking element within the opening. 11. The locking mechanism of claim 5, wherein said locking element is a cable attached to the hubs and spanning the entire width of the flexible cover. 12. The locking mechanism of claim 11, wherein said hub includes a fastening element configured for removably fastening said cable to each hub. 13. The locking mechanism of claim 12, wherein each hub defines an opening through which said cable is received and said fastening element includes a bore intersecting the opening and a set screw configured for engagement within said bore and arranged to bear against said cable to lock said cable within the opening. 14. The locking mechanism of claim 5, wherein said locking element includes a pair of rods, one each mounted to a corresponding hub and each rod sized to extend across less than half the width of the cover. 15. The locking mechanism of claim 14, wherein each of said rods is removably mounted to a corresponding hub. 16. The locking mechanism of claim 15, wherein each hub defines a threaded opening and each of said rods includes a threaded end configured to be threadedly engaged within the threaded opening of the corresponding hub. 17. A cover system for covering a container, comprising: a roller assembly rotatably supported on the container;a flexible cover wound onto said roller assembly to be extended from the roller assembly to a fully extended length or retracted to be fully wound onto the roller assembly upon rotation of said roller assembly; anda locking element mounted to and rotatable with said roller assembly and spanning a substantial portion of the width of said cover, said locking element arranged on said roller assembly such that a portion of the length of said cover is wound over said locking element when the cover is wound onto the roller assembly, said portion having a length less than the entire length of said cover and corresponding to fully extended length of said cover. 18. The cover system of claim 17, wherein said locking element is a cable spanning the entire width of the flexible cover. 19. The cover system of claim 17, wherein said locking element is removably mounted to said roller assembly. 20. The locking mechanism of claim 17, wherein said roller assembly includes hubs at opposite sides of said cover, said hubs each defining an opening through which said locking element is received and including a fastening element configured for fastening said locking element within said opening.
