The invention relates to a crane (1), in particular a bridge crane or gantry crane, comprising at least one horizontally extending crane girder (2), which is designed as a lattice girder having a plurality of braces (5, 5h, 5i) and on which a crane trolley (9) having a lifting device can be moved. At least some of the braces (5, 5h, 5i) are planiform, and each of the planiform braces (5, 5h, 5i) has a flat main surface (5a), which extends transversely to a longitudinal direction (LR) of the crane girder (2). On each longitudinal side (5b) of the braces (5, 5h, 5i), a first cut-out (5c) and a second cut-out (5d) are provided in the main surfaces (5a). In order to provide such a crane (1) having at least one improved crane girder (2), according to the invention, the longitudinal sides (5b) of at least some of the planiform braces (5, 5h, 5i) are free of edge bends at least between the first and second cutouts (5c, 5d).
