The invention belongs to the technical field of bridge construction instruments, and discloses an anti-shaking structure of a rail-mounted beam lifter. A cross beam supporting structure is installed at the lower end of a cross beam, and a roller bracket is fixed at the lower end of the cross beam supporting structure; a rotating shaft is fixed on the roller bracket through a bearing, and a roller is fixed on the rotating shaft through a connecting key; a control structure and a sliding rail are installed at the upper side of the cross beam, and a movable lifting structure is slidably connected to the sliding rail; the cross beam supporting structure is provided with a rear side cross beam supporting rod and a front side cross beam supporting rod, and a first supporting rod is installed between the rear side cross beam supporting rod and the front side cross beam supporting rod; and a transverse hydraulic rod is installed in the middle of the first supporting rod, a vertical hydraulic rod is installed at the end of the transverse hydraulic rod, and a clamping plate is installed on the vertical hydraulic rod. According to the anti-shaking structure, the bridge can be effectively prevented from shaking, and the stability of the bridge in the transportation and installation process is improved; and meanwhile, the corresponding safety coefficient is improved.
