The invention relates to a crane, in particular an overhead crane or gantry crane, having at least two crane girders that extend horizontally in a longitudinal direction. The crane is designed as trussed girders and each girder includes an upper run with a moveable crane trolley and lifting gear. Each crane girders is composed of two upper run profiles that are connected together via a running rail for the crane trolley. By way of such a design, particularly simple assembly of the crane girders or of the crane can be achieved. Therefore, commercially available, conventional structural steel can be used for the upper run, from which the upper run is produced in a simple manner in terms of manufacturing technology by simple connection to a corresponding running rail.

1. A crane comprising: at least two crane girders that extend horizontally in a longitudinal direction, wherein the girders are designed as trussed girders and each includes an upper run configured to support a movable crane trolley having a lifting gear, wherein the upper runs are each composed of a first upper run portion and a second upper run portion, which two upper run portions are connected together by a running rail positioned atop and spanning a gap defined between the two upper run portions of each upper run. 2. The crane of claim 1, wherein the upper run portions each comprise a horizontal flange and in each case the running rail is attached to upper sides of two adjacent flanges in order to connect the upper run portions of one of the upper runs. 3. The crane of claim 2, wherein the upper run portions are formed as angular profile girders and each include a vertical web adjoining the respective flange. 4. The crane of claim 3, wherein the crane girders designed as trussed girders comprise struts and posts that each have upper apertures, into which the vertical webs protrude. 5. The crane of claim 2, wherein the running rail is arranged centrally between the upper run portions. 6. The crane of claim 2, wherein the upper run portions are formed as angular profile girders and each include a vertical web adjoining the flange. 7. The crane of claim 6, wherein the vertical webs extend in parallel with each other and are spaced apart from each other by the gap. 8. The crane of claim 2, wherein the running rail is welded to the upper run portions. 9. The crane of claim 1, wherein the running rail is arranged centrally between the upper run portions. 10. The crane of claim 9, wherein the upper run portions are formed as angular profile girders and each include a vertical web adjoining the flange. 11. The crane of claim 10, wherein the vertical webs extend in parallel with each other and are spaced apart from each other by the gap. 12. The crane of claim 9, wherein the running rail is welded to the upper run portions. 13. The crane of claim 1, wherein the running rail is produced from a solid material. 14. The crane of claim 1, wherein the running rail has a rectangular cross-section. 15. The crane of claim 1, wherein the running rail is welded to the upper run portions. 16. A crane comprising: at least two crane girders that extend horizontally in a longitudinal direction, wherein the girders are designed as trussed girders and each includes an upper run configured to support a movable crane trolley having a lifting gear;wherein the upper runs are each composed of a first upper run portion and a second upper run portion;a running rail positioned atop and spanning between the two upper run portions of each upper run, wherein the two upper run portions are connected together by the running rail;wherein the upper run portions are formed as angular profile girders and each include a vertical web adjoining a horizontal flange; andwherein the vertical webs extend in parallel with each other, are spaced apart from each other by a gap, and the gap is bridged by the running rail. 17. The crane of claim 16, wherein the crane girders designed as trussed girders comprise struts and posts that each have upper apertures, into which the vertical webs protrude. 18. The crane of claim 16, wherein the running rail is arranged centrally between the upper run portions, and wherein the crane girders designed as trussed girders comprise struts and posts that each have upper apertures, into which the vertical webs protrude. 19. The crane of claim 18, wherein the upper run portions each comprise a horizontal flange and in each case the running rail is attached to upper sides of two adjacent flanges in order to connect the upper run portions of one of the upper runs. 20. A crane comprising: at least two crane girders that extend horizontally in a longitudinal direction, wherein the girders are designed as trussed girders and each includes an upper run configured to support a movable crane trolley having a lifting gear;wherein the upper runs are each composed of a first upper run portion and a second upper run portion;a running rail positioned atop and spanning between the two upper run portions of each upper run, wherein the two upper run portions are connected together by the running rail;wherein the upper run portions are formed as angular profile girders and each include a vertical web adjoining a horizontal flange; andwherein the crane girders designed as trussed girders comprise struts and posts that each have upper apertures, into which the vertical webs protrude.
