In terms of safety performance, it is equipped with safety hoisting modules such as anti-overrun, anti-slip hook, anti-impact, anti-sway, and anti-hanging, which can effectively reduce safety risks during construction and build a solid safety defense line for construction operations. At the same time, its adopted ZPI intelligent hoisting system further guarantees the safety of operation through intelligent means. In some super high-rise building projects, this tower crane, relying on these safety configurations, completes the lifting tasks stably and efficiently, and strongly guarantees the safe progress of the project. In terms of operation experience, the Zhongtian 7023-12 tower crane is equipped with a large integrated cab, creating an electrical three-proof environment of moisture-proof, dust-proof, and high-temperature-proof, providing drivers with a larger and more comfortable operating space, helping to improve the driver's concentration and comfort during operation, reducing operation errors caused by environmental factors, and thereby improving work efficiency. In actual construction, drivers generally report that this tower crane operates smoothly and has a good driving experience. In terms of performance parameters, the boom length of this tower crane is suitable for various construction scenarios. The maximum working range reaches 70m and can flexibly cover a larger construction range. The maximum lifting weight is 12t, and the rated torque is 2500KN/m, which can meet the lifting needs of various building materials. Whether it is light building accessories or heavier prefabricated components, it can be easily handled. Its independent lifting height is 60m, the rated lifting speed is 1.33m/s, and the rated lifting height is 228m. It is efficient and fast in material lifting and effectively shortens the construction period. In addition, if this tower crane belongs to the flat-head tower design, it also has unique advantages. Compared with traditional tower cranes with tower heads, it greatly reduces the requirements for the lifting capacity of hoisting equipment during disassembly and assembly. It has a small unit mass and a low installation height. The maximum installation height can be reduced by more than 10m compared to other tower cranes of the same level. It not only saves disassembly and assembly costs but also is more safe and fast. When multiple tower cranes cross-operate, the height difference between every two intersecting ones can usually be reduced to 3m. The overall height is reduced, the installation time is reduced, the requirements for installation equipment are low, and it can also reduce the ballast of each tower crane and adopt a smaller tower body section and undercarriage. The effective height of the hook is increased, and the space utilization rate is high. It is suitable for construction in occasions with special height requirements such as airport reconstruction and expansion, near airports, in tunnels, in factories, and under high-voltage lines. The special connection method of the boom section and the absence of a tower head and tie rods make the disassembly and assembly of the boom section by section easy and safe. During construction, the boom length can be conveniently changed in the air to meet different construction needs. When the construction site is limited and truck cranes cannot approach, the unique boom connection method can be used to disassemble and assemble section by section in the air, facilitating the installation and disassembly of the tower crane. The steel structure of its boom has a long service life and high safety. It is not affected by alternating stress in both vertical and horizontal directions, reducing the risk of boom fatigue damage, even fracture, and weld cracking. The boom design is easy to realize modularization. The boom sections of flat-head towers of different levels in the same series can be mutually utilized, improving the applicability and utilization rate of the boom.
