With scientific and technological innovation and technological development, the construction period required for large-scale buildings is getting shorter and shorter, and the working conditions and operating environments are becoming more and more dense and narrow, and the role of flat-top tower cranes is becoming more and more significant. increasing day by day.

The flat-top tower crane has the advantages of novel design, reasonable structure, safety, high reliability, and strong anti-fatigue and impact ability.

The steel structure has long service life and high safety: Compared with the horizontal arm tower crane with tower head and tie rod, the connection method and stress condition of the arm frame of the flat head tower crane are obviously different, and the upper structure is horizontal and rigid. The boom tie rod is free from alternating stress in both vertical and horizontal directions, which greatly improves the service life and safety of the boom steel structure. The tie-free design reduces the height of the tower top and meets the requirements of different working conditions. It is especially suitable for the disassembly and assembly of tower cranes under the condition of cross operation of group towers and restricted construction sites, which greatly improves the operation efficiency of tower cranes and its unit quality. Small, low installation height, can reduce the height difference between towers, save space and save costs.
