After the tower section is jacked up by one tower section height through the hydraulic cylinder, a new tower section is installed in the lowermost jacking cage, and the overall lifting of the tower crane is realized by the above method.

By adopting the above technical solution, the beneficial effect that can be achieved is that by setting the first slide rail and the second slide rail that are perpendicular to each other, the crane can move laterally and vertically, so a shorter boom can be set, and the construction can be realized. The construction scope is fully covered, and the lifting capacity can be guaranteed, and the tower crane has a simple structure and high practicability. In addition, the main body of the tower crane is supported by several lifting column components and realizes the overall lifting, and is connected to each other through the fixed beam and movable beam at the top to form a whole. Compared with the single tower structure commonly used at present, the stability is significantly enhanced, especially in scraping Strong wind resistance in severe weather such as typhoons.
