FIELD: mechanical engineering.
SUBSTANCE: invention relates to overhead cranes. The box-shaped crane girder (1) has two side plates (2a, 2b) spaced apart from each other, at least one belt plate (2c, 2d) connecting the two side plates (2a, 2b) to each other, and at least one a transverse plate (5), which is located between the side plates (2a, 2b), connecting the side plates (2a, 2b) to each other. A welded joint is provided between the respective shoulder plate (2c, 2d) and the side plates (2a, 2b). Between the transverse plate (5) and each of the two side plates (2a, 2b), at least one form-fit connection, in particular a plug-in connection, was provided.
EFFECT: simplification of the manufacturing process.
