Analysis of Lifting Equipment Selection and Technical Requirements for Large Double-Curved GRC Panel Installation

In the field of modern architectural decoration, large-size double-curved GRC panels have become the preferred material for many high-end projects such as landmark buildings and commercial complexes, thanks to their unique curved shapes and artistic expressiveness. However, the selection of lifting equipment and the control of technical requirements during installation directly affect construction safety, efficiency, and the final presentation. As an industry leader with 28 years of experience in detailed design, manufacturing, and installation of UHPC/GRC/GRG/GRP materials, Qinglong Group (hereinafter referred to as Qinglong) will leverage its full-chain service advantages to provide an in-depth analysis of the selection logic and technical key points of lifting equipment for large-size double-curved GRC panel installation.

### I. Core Requirements of Large-Size Double-Curved GRC Panels for Lifting Equipment Large-size double-curved GRC panels typically feature "large spans, irregular curved surfaces, and heavy single-piece weights." The selection of lifting equipment must balance three core elements: load-bearing capacity, operating radius, and precision control. First, the equipment's load capacity must be calculated based on the actual weight of the GRC panels (usually 150-300kg/㎡) and additional hoisting loads, ensuring a safety factor of no less than 1.5 times. Second, the double-curved shape demands extremely high precision in hoisting angle and position, so the equipment must have fine-tuning functions to meet the spatial positioning needs of curved surface installation. In addition, the construction site environment (such as building height and site restrictions) also affects equipment selection—for example, narrow sites are better suited to telescopic boom cranes, while super high-rise projects require coordinated operation of tower cranes and aerial work platforms. Within Qinglong's 600,000-square-meter annual production capacity at its Nanning production base, standardized technical reserves for the hoisting of double-curved GRC panels have been established, allowing rapid matching of the optimal equipment combination according to project characteristics.

### II. Adaptability Analysis and Selection Strategy of Mainstream Lifting Equipment The lifting equipment commonly used in the construction industry currently includes truck cranes, crawler cranes, tower cranes, and hydraulic lifting platforms. For the installation of large-size double-curved GRC panels, differentiated selection is required based on project parameters. Truck cranes offer strong flexibility and are suitable for dispersed hoisting at mid- and low-rise buildings, but are limited by operating radius and stability; crawler cranes have outstanding load-bearing capacity (up to thousands of tons) and are suitable for the overall hoisting of extra-large GRC panels, with particularly clear advantages in complex terrain; tower cranes are suitable for continuous operations on high-rise buildings and can achieve precise positioning through pre-set tracks. In the Century Plaza renovation project on Nanjing East Road, Qinglong adopted a combined solution of "tower crane + hydraulic fine-tuning device" to successfully complete the installation of irregular translucent double-curved GRC panels, with errors controlled within ±2mm, confirming the synergistic value of equipment selection and technical innovation.

### III. Technical Key Points and Quality Control During Installation The efficient operation of lifting equipment depends on rigorous technical control. Before installing large-size double-curved GRC panels, 3D scanning and modeling must be performed, with BIM technology used to simulate hoisting paths to avoid collision risks in advance. During hoisting, special lifting tools (such as vacuum suction cups and flexible slings) should be used to avoid damage to the GRC panel surface, and a real-time monitoring system should be equipped to ensure the hoisting angle deviation does not exceed 0.5°. In addition, the installation precision of the anchoring system directly affects panel stability. Through the dual safeguard of "pre-embedded connectors + on-site pull-out tests," Qinglong ensures that the load-bearing capacity of every anchor point complies with the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). In the Dongguan Women and Children's Activity Center project, Qinglong achieved zero-accident installation of double-curved GRC curtain walls thanks to its full-process quality control system, winning the Silver Award of the First GRC Building Engineering Innovation Award of the AALBORG WHITE Cup.

### IV. Full-Chain Service Empowering Lifting and Installation Efficiency As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong empowers the hoisting efficiency of large-size double-curved GRC panels from the source. At the design stage, structural optimization reduces panel weight (such as using hollow structures and lightweight aggregates), lowering the load requirements for lifting equipment. In production, automated mold forming technology ensures the consistency of the double-curved radian and reduces on-site adjustment work. During construction, Qinglong relies on its nationwide office network to deploy localized technical teams, quickly responding to on-site needs with over 20 years of project experience. This integrated "design-production-construction" service model not only shortens project timelines but also fundamentally guarantees hoisting safety and precision.

The selection of lifting equipment and technical requirements for installing large-size double-curved GRC panels is a comprehensive matching process involving material properties, engineering needs, and equipment performance. Based on 28 years of professional expertise, Qinglong Group provides designers and owners with expert solutions from scheme design to implementation through technical innovation and full-chain services, helping to create more architectural works that combine aesthetic value with structural safety. In the future, Qinglong will continue to uphold the values of "honesty, striving, trust, and collaboration," promote the innovative application of UHPC/GRC/GRG/GRP materials in the field of architectural decoration, and steadily advance toward the vision of "becoming an outstanding manufacturing-leading enterprise in the world."
