"Kranträger, insbesondere Laufkranträger"."Crane girders, especially overhead crane girders".
Kranträger, insbesondere Trager für Laufkrane, bestehen im allgemeinen aus zwei Trägerpaaren, wobei jedes taar von einem Hauptträger und einem Nebentrüger (Bühnentxägsr) gebildet wird» Die üauptträger haben die Aufgabe, die gesamte Lest zu tragen, während die Nebenträger zur eeitlichen Versteifung und zur Aufnahme kleiner Lauten ,Crane girders, especially girders for overhead traveling cranes, generally consist of two pairs of girders, each of them taar from a main girder and a secondary girder (Bühnentxägsr) is formed »The main girders have the task of carrying the entire load, while the secondary girders carry the lateral stiffening and for picking up small sounds,

wird dieses Ziel dadurch erreicht, dass Haupt- und Nebenträger jeden Trägex^paares zu einem geechloseenen Kastenträger

create that is so trained that it is able to absorb all of the above-mentioned forces without the use of special fever carriers, which leads to a weight saving and a simplification in terms of manufacturing technology. According to the invention, this goal is achieved in that the main and secondary girders of each pair of girders are combined to form a single box girder. This can be done, for example, by replacing the main girder with two individual girders of approximately the same load-bearing capacity and connecting them to one another with full walls at the top and bottom.
Die unsymmetrische Belastung dee Querschnittes «ines solchen Trägers durch die seitliche Anordnung der Fahrbahnschiene ist unschädlich, da ein geschlossener Kaetenträger erhebliche Torsionsbeanspruchungen aufzunehmen vermag.The asymmetrical loading of the cross-section “Ines such a carrier due to the lateral arrangement of the track rail is harmless as a closed one Kaetträger take up considerable torsional loads able.

Anstatt die Träger aus ebenen Blechen zusammenzusetzen, kann man in gewiesen Fällen auch abgekantete Bleche veiwenden, wie es in den Abb. 5» 4 und 5 schematisch dargestellt, ist. Auf diese Y/eise wird an Schweissarbeit gespart. Instead of assembling the beams from flat sheet metal, folded sheets can be used in certain cases, as shown schematically in Figs. 5, 4 and 5. In this way, welding work is saved.
