The invention discloses a direction changeable transverse beam for a bridge crane. The direction changeable transverse beam comprises a straight rail which is fixed on an upper end transverse beam of a supporting framework of the bridge crane, and a walking trolley which is arranged on the upper end transverse beam of the supporting framework of the bridge crane and is matched with the straight rail to guide and walk; the direction changeable transverse beam further comprises a direction changing rail with a certain radian; the direction changing rail is assembled at the tail end of the straight rail by a bolt; the size of the direction changing rail is completely the same as the structure size of the straight rail; pulleys, which are located on the lower end face of the walking trolley and are matched with the straight rail, are universal wheels; the centers of the direction changing rail and the straight rail are provided with linear bulges the same as a guide track; the linear bulges are vertically fixed on the surfaces of the direction changing rail and the straight rail; and the pulleys are provided with guide grooves for embedding and guiding the linear bulges. With the adoption of the technical scheme, the walking trolley can realize movement through dragging, and the pulleys of the walking trolley are the universal wheels so that the direction of the walking trolley can be changed on the direction changing rail, and the linear bulges of the guide rail and the guide grooves of the pulleys are matched so that the stable guide effect is realized.
