convenient to dismantle and install the tower crane under the limited condition of the construction site. If limited by the field conditions, the flat tower is undoubtedly the best solution when the truck crane cannot approach. Because of the unique boom connection mode of the flat-head tower, the whole boom can be disassembled and assembled in the air section by section, and the boom can be directly removed from the transport vehicle when necessary.

Topless tower crane and Topkit tower crane each have their own scope of application, therefore, in the actual construction process, because the construction of material is crucial

Low design cost. The design of flat-head tower saves the design and calculation of tower head and pull rod, and the calculation condition of lifting arm is less, the mechanical model is simple, the calculation amount is greatly reduced, the calculation result is more close to the actual value, convenient for modular design, thus greatly reducing the design cycle.

The crane has good applicability and high utilization rate. It is very important that the design of flat head tower crane is easy to realize modularization. For the manufacturer, the design and manufacturing costs can be greatly reduced by the modular boom, thus reducing the flat-head tower price; For users, can give full play to the flexibility and adaptability of the boom.

The flat-head tower crane arm section special connection way and does not have the tower head, the pull rod, makes its hoisting arm section by section disassembly very simple.

The boom steel structure has long life and high safety. The flat head tower is more stable than the ordinary tower crane, especially in the rotary or emergency braking,
