Heavy-duty overhead crane, with outstanding performance
In the construction of prefabricated high-rise buildings, the prefabricated components often have the characteristics of heavy single-piece weight and high frequency of lifting. Taking the large flat-head tower cranes that have been widely used in several regions recently as an example, their rated lifting moment can reach several thousand ton-meters, and the maximum lifting capacity easily exceeds the 100-ton mark. In actual construction, even at the end of the extremely long arm, it can still maintain strong lifting capacity, perfectly meeting the lifting requirements of heavy components such as prefabricated shear wall panels, composite floor slabs, and prefabricated stairs. In addition, the unique "cycloidal speed control technology" of the flat-head tower crane can achieve millimeter-level micro-motion operation. Combined with the load adaptive and load-dependent speed functions, it ensures the smooth and precise connection of heavy components at high altitudes, significantly reducing the damage rate of components and installation errors.
Flat layout, multiple towers enhance efficiency
Compared with traditional tower cranes with tower heads, the flat-head tower cranes eliminate the complex top A-frame and pull rod structures. This design demonstrates unparalleled advantages in urban core areas with limited space and in scenarios involving multi-tower cross-operation. The compact head design not only reduces the collision risk during group tower operations but also allows for a smaller safety distance between the tower cranes, enabling seamless collaboration of multiple equipment on the same operation surface. Data shows that in super high-rise building projects where multiple flat-head tower cranes operate collaboratively, the construction team can carry out staggered construction on different floors. The overall completion speed is approximately 27% faster than the traditional mode. Some projects even shortened the standard floor structure construction period to 5 days per floor, increasing the speed compared to traditional poured construction by more than 30%.
With intelligent scheduling, vertical transportation says goodbye to "waiting periods"
In addition to the significant improvement in hardware performance, modern large-tonnage flat-head tower cranes have also deeply integrated intelligent control technology. By installing a highly integrated intelligent manager system and combining BIM technology with real-time GPS scheduling, the construction party can precisely plan and dynamically adjust the operation routes of the tower cranes. This digital management model effectively eliminates the "time gap" between material distribution and lifting operations, reducing the idle waiting time of the tower cranes. At the same time, the modular structure of the flat-head tower crane shortens its installation and dismantling time by approximately 30% compared to traditional equipment, further compressing the non-production time for pre-preparation and dismantling.
Industry experts point out that the wide application of large-tonnage flat-head tower cranes marks that the construction of prefabricated buildings is moving towards a new stage of high mechanization and intelligence. It not only ensures the efficient and safe lifting of prefabricated components from the equipment level, but also optimizes the on-site logistics and vertical transportation system, saving comprehensive costs for construction enterprises and becoming an important tool for promoting a strong transportation province and high-quality development of building industrialization.
