Description

Turnover System and Method for Heavy Structures The present invention relates to an inversion system and method, and more specifically, to an inversion system and method for inverting heavy structures, such as rectangular concrete structures used in semiconductor business unit facilities. In the fabrication and construction sites of heavy-duty structures, it is often necessary to perform processes such as pouring, curing, and finishing on the underside as well as the top surface. For example, during the construction of factories or plants where large-scale industrial facilities are installed, long and heavy-duty structures, such as concrete structures reaching tens of meters in length, are used. To perform work on both the top and bottom surfaces of such structures, processes to change the orientation of the structure or invert it 180 degrees are essential. However, due to the heavy weight and diverse size and shape of the structures, it is difficult to simultaneously ensure stability and work efficiency through simple heavy equipment operation alone, and the need for specialized inversion technology is continuously increasing. Conventionally, the inversion of heavy structures has been performed by lifting the structure using lifting equipment such as cranes, chain blocks, or lifting slings, followed by on-site manual adjustments by workers or the use of simple rotating frames. However, as the length and weight of the structure increase, this method can lead to significant shaking, eccentricity, and vibration during the rotation process. This poses a high risk of not only structural damage but also collisions with surrounding equipment and worker safety accidents. Furthermore, since a significant portion of the lifting and inversion operations relies on the experience and manual labor of skilled workers, there are issues such as variations in work quality and increased process time. Therefore, there is an urgent need to develop inversion technology for heavy-duty structures that can safely invert long poles and heavy-duty structures through uniform attitude control while stably fixing them, flexibly adapt to various sizes and shapes of structures, and simultaneously improve process efficiency and safety by suppressing risks such as shaking, eccentricity, and slipping during the inversion process while minimizing operator intervention.
