The present invention relates to box girder (1), in particular crane girder, having two side plates (2a, 2b) spaced apart from each other, at least one chord plate (2c, 2d) connecting the two side plates (2a, 2b) to each other and at least one transverse plate (5) that is arranged between the side plates (2a, 2b) connecting the side plates (2a, 2b) to each other, wherein a welded joint is provided between the respective chord plate (2c, 2d) and the side plates (2a, 2b). In order to facilitate the manufacturing process of a box girder (1), in particular a crane girder,it is suggested, that at least one form-fitting connection, in particular plug-in connection, is provided between the transverse plate (5) and each of the two side plates (2a, 2b). In addition, the invention also relates to a crane having such a box girder (1) and to a corresponding manufacturing method therefor.

    La présente invention concerne une poutre-caisson (1), en particulier une poutre de grue, laquelle poutre a deux plaques latérales (2a, 2b) espacées l'une de l'autre, au moins une plaque de corde (2c, 2d) reliant les deux plaques latérales (2a, 2b) l'une à l'autre et au moins une plaque transversale (5) qui est disposée entre les plaques latérales (2a, 2b), reliant les plaques latérales (2a, 2b) l'une à l'autre, un raccord soudé étant disposé entre la plaque de corde respective (2c, 2d) et les plaques latérales (2a, 2b). Afin de faciliter le processus de fabrication d'une poutre-caisson (1), en particulier d'une poutre de grue, il est suggéré qu'au moins une liaison à adaptation de forme, en particulier une liaison enfichable, soit disposée entre la plaque transversale (5) et chacune des deux plaques latérales (2a, 2b). De plus, l'invention concerne également une grue ayant une telle poutre-caisson (1) et un procédé de fabrication correspondant pour celle-ci.
