The invention relates to a tower crane hydraulic jacking system and a tower crane. The hydraulic jacking system of the tower crane comprises a jacking cross beam (10) provided with four side frames, and the four side frames are sequentially connected to form a rectangular enclosure frame; the climbing frame (20) is positioned on the upper side of the jacking cross beam (10); the jacking oil cylinder group (30) is connected between the climbing frame (20) and the jacking cross beam (10) and is configured to enable the climbing frame (20) to ascend or descend relative to the jacking cross beam (10); the hydraulic driving system is in driving connection with the jacking oil cylinder group (30) and is configured to hydraulically drive the jacking oil cylinder group (30), the jacking oil cylinder group (30) comprises eight jacking oil cylinders, each side frame is connected with two jacking oil cylinders of the eight jacking oil cylinders, and the jacking oil cylinders of the jacking oil cylinder group (30) are driven by the hydraulic driving system. The connection points of the four side frames and the eight jacking oil cylinders are located at the adjacent positions of the corners of the rectangular enclosure frame.
