The invention discloses a cross beam of a bridge crane. The cross beam comprises transmission bases; the transmission bases comprise motors; the driving ends of the motors are connected with transmission wheels; straight teeth are arranged on the surfaces of the transmission wheels; adjusting rods are fixedly connected at the lower ends of the transmission wheels; loading rods are arranged outsidethe adjusting rods; adjusting bolts are rotationally mounted on the surfaces of the loading rods; abutting blocks are fixedly connected at the lower ends of the loading rods; a plurality of oblique teeth are distributed at the lower end of each abutting block; bearing guiding rails are arranged at the lower ends of the transmission bases and adopt I-shaped structures; straight tooth connecting openings and oblique tooth connecting openings are formed in the surfaces of the bearing guiding rails; the bearing guiding rails mesh with the straight teeth of the transmission wheels through the straight tooth connecting openings; and the bearing guiding rails mesh with the oblique teeth of the abutting blocks through the oblique tooth connecting openings. The cross beam can adapt to the bearingguiding rails in different sizes, the transmission wheels and the abutting blocks mesh with the bearing guiding rails, thus force transmission is facilitated, and the problems of rail gnawing and derailing are avoided.
