摘要
A crane, in particular an overhead crane or gantry crane, comprising at least one crane girder, which extends horizontally and is designed as a trussed girder having an upper run and a lower run. A crane trolley having a lifting device can be moved on the crane girder. The invention further relates to a method for assembling a crane girder, comprising an assembly step for producing the trussed structure of the crane girder. The crane girder includes an adapter on at least one of the two opposite ends, which adapter can be fastened to the upper run and the lower run in such a way that the adapter can be oriented relative to the upper run and the lower run and then the adapter can be welded onto the upper run and the lower run in a desired position.
