The utility model relates to a suspension device for a ladle hot repair hydraulic cylinder. The suspension device comprises a base, a central column, a transverse rod and a hook. The central column is rotationally connected with the base, the rotation axis of the central column is perpendicular to the horizontal plane, the rear end of the transverse rod is perpendicularly fixed to the upper end of the central column, the hook is connected onto the transverse rod and is used for being connected with the hydraulic cylinder, and an oil pipe of the hydraulic cylinder is wound on the central column and the transverse rod. The suspension device has the advantages that the hydraulic cylinder can be suspended on the suspension device, the oil pipe can be fixedly bound with the transverse rod along with the central column, and accordingly workers do not need to carry out loaded operation or drag the oil pipe; the central column can rotate, so that the hydraulic cylinder can rotate among multiple hot repair stations and can be used at the multiple hot repair stations.
