The invention belongs to the technical field of buildings and relates to an axial deviation eliminating mechanism for a supporting cross beam of a tower crane. The technical problem that in the prior art, smoothness is not enough in the moving process of a tower crane is solved. The axial deviation eliminating mechanism comprises the supporting cross beam used for being connected with the tower crane. The supporting cross beam comprises a supporting beam and a supporting rod, wherein the axis of the supporting beam and the axis of the supporting rod coincide. The supporting beam and the supporting rod are connected through a movable sleeve, and the movable sleeve is provided with an axial deviation eliminating assembly which enables the supporting beam and the supporting rod to be fixedly connected or to be capable of axially moving in the movable sleeve. By means of the axial deviation eliminating mechanism, the working stability and the load amount of the tower crane can be improved, the length of the supporting cross beam can be automatically adjusted in the walking process of the tower crane, and thus the tower crane can walk smoothly.
