CRAIN GIRDER FOR A CRANE, IN PARTICULAR FOR AN OVERHEAD OR GANTRY CRANE, AND A CRANE COMPRISING SUCH A GIRDER

摘要

The invention relates to a crane girder (2) for a crane (1), in particular for an overhead or gantry crane, said crane girder being designed as a trussed girder with an upper chord (3), a lower chord (4), and braces (5) connecting said chords to each other. At least one of the braces (5) is designed flatly and has a main surface (5a) which extends transversely to a longitudinal direction (LR) of the crane girder (2). The aim of the invention is to provide an improved crane girder (2). This is achieved in that the brace (5) is removably secured to the upper chord (3) and/or the lower chord (4). The invention also relates to a crane (1) comprising a corresponding crane girder (2).
