The present invention relates to a device for lifting an upper structure of a bridge, which is characterized by comprising: a frame unit which is constructed at a location adjacent to a hydraulic jack; an auxiliary lifting member which is coupled to the frame unit and adjusts a displacement amount of an upper structure; a displacement driving unit which is fixedly coupled to the upper end portion of the auxiliary lifting member, and is coupled with a first sensor member to measure an initial displacement value of the upper structure; a displacement measurement unit which is rotatably coupled to the displacement driving unit, comes in tight contact with the lower surface of the upper structure, and comprises a second sensor member which acquires and transmits rotation amount information of a contact panel and location movement information of the upper structure; and a control device which is configured such that various data may be transmitted to and received from the first and second sensor members by a wired and wireless communication method, analyzes the initial displacement amount value, the rotation amount information of the contact panel, and the location movement information of the upper structure that are individually transmitted from the first and second sensor members in order to generate displacement amount information with respect to the upper structure which is lifted, and controls the operation of the auxiliary lifting member based on the generated displacement amount information. Therefore, the upper structure can be lifted in a safe and precise manner.
