The invention relates to a jacking device for replacing a saddle arm of a rotating bearing of a continuous casting rotating table and a construction method of the jacking device. The method includes the steps that a saddle arm supporting device is arranged, four hydraulic jacks of the same model are placed at the corresponding positions of the saddle arm, the hydraulic jacks are started, the lifting heights keep consistent, and jacking is performed in segments till the rotating bearing can transversely move and will not make any contact with a rotating table body; after the bearing is slowly pulled to a bearing transverse movement support through a chain block, a new bearing is allocated and transported to the bearing transverse movement support; after a collecting and guiding rail of the new bearing is pulled into a base and centered, the bearing is lifted, an erected steel pipe is detached, and the bearing is totally in place; and a body falls back; a saddle arm supporting system is detached, a hydraulic jacking system is detached, and the transverse movement support is detached. According to the jacking device, the whole rotating table body does not need to be hoisted away, the hydraulic synchronous jacking technology is adopted, and transverse replacement of the rotating large bearing is achieved; and the whole device is made of common steel materials, and cost is low.
