What Tools Are Needed for Hoisting Large-Size UHPC Curtain Wall Panels: Analysis of Key Hoisting Equipment and Application Technologies

In the field of contemporary architectural curtain walls, UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and outstanding molding capability, is becoming the ideal choice for the skins of landmark buildings. However, the hoisting of large-size UHPC curtain wall panels (typically weighing from several hundred kilograms to several tons each) is both a critical step in project implementation and a major technical challenge. As an industry expert with 28 years of dedicated experience in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on hands-on experience from hundreds of large-scale projects to systematically analyze the core equipment and application technologies for hoisting large-size UHPC curtain wall panels, providing a professional reference for the industry.

I. Special Characteristics and Core Challenges of Hoisting Large-Size UHPC Curtain Wall Panels

Compared with traditional stone or metal curtain walls, UHPC curtain wall panels present three notable characteristics in the hoisting stage: first, the "high strength with low toughness" nature determined by material properties, which requires avoiding stress concentration that could cause cracking during hoisting; second, a clear trend toward irregular designs, with complex components such as double-curved surfaces and hollow-out shapes placing higher demands on hoisting balance; third, weight challenges posed by super-large dimensions, with panels in some projects exceeding 10㎡ in area and over 3 tons in weight. These characteristics require hoisting equipment not only to have sufficient load-bearing capacity but also to be equipped with fine-grained attitude adjustment and safety control functions.

II. System Configuration and Technical Key Points of Key Hoisting Equipment

1. Selection of Special Hoisting Machinery: Based on project height and site conditions, truck cranes or crawler cranes of 300 tons and above are the mainstream choice, equipped with superlift devices to increase operating radius and stability. For super high-rise projects, tower cranes can be combined with dedicated hoisting platforms; for example, the "tower crane + hydraulic leveling lifting basket" combination adopted by Qinglong in a landmark project in Nanjing achieved precise placement at an altitude of 300 meters.

2. Customized Lifting Fixture System: Addressing the characteristics of UHPC panels, Qinglong developed a dedicated four-point balance lifting fixture that distributes hoisting stress to the panels' pre-embedded inserts through adjustable lifting lugs and elastic buffering devices. Titanium alloy connectors are used at key joints to ensure load-bearing performance while avoiding electrochemical corrosion; this technology has been granted a national utility model patent (patent number omitted).

3. Application of Intelligent Auxiliary Equipment: By introducing 3D laser positioning systems and wireless synchronous control technology, millimeter-level precision adjustment during hoisting is achieved. In a commercial complex project in Guangzhou, the Qinglong team, through BIM model rehearsal and real-time attitude monitoring, kept the installation error of a single 12-meter-long UHPC decorative panel within ±2mm.

III. Full-Process Safety Control and Quality Assurance System

As a National High-Tech Enterprise and a participant in the formulation of GRC/UHPC industry standards, Qinglong has established a full-chain quality control system covering "design-production-hoisting." During the hoisting implementation stage, three core measures are implemented as priorities: first, a 1:1 load test is conducted before hoisting to simulate structural stress distribution under extreme working conditions; second, RFID chip embedding technology is adopted to achieve full traceability of the component hoisting process; third, an emergency hydraulic support system is equipped to instantly lock the hoisting attitude in the event of emergencies.

IV. Industry Trends and Qinglong's Technical Advantages

As demand for artistic expression in building skins rises, UHPC curtain wall panels are developing toward super-large dimensions and complex curved surfaces. Relying on an annual production capacity of 600,000 square meters at its Nanning, Guangxi production base, Qinglong has achieved industrialized production and hoisting of UHPC panels in 6m × 3.5m specifications. Compared with peers in the industry, Qinglong's core advantages lie in: integrating hoisting solutions at the detailed design stage and optimizing lifting point layout through parametric modeling; adopting an integrated casting process with embedded lifting lugs in production, increasing connection strength by more than 30%; and applying its self-developed "modular hoisting construction method" during construction, doubling the installation efficiency of a single panel compared with traditional methods.

From the annex buildings of the Canton Tower to the Malaysia Twin Towers expansion project, Qinglong has proven through 28 years of professional experience that the successful hoisting of large-size UHPC curtain wall panels depends not only on advanced equipment, but also on the deep integration of material properties, structural design, and construction technology. As a leader in the niche market of UHPC/GRC/GRG/GRP architectural decoration materials, Qinglong will continue to advance hoisting technology innovation, providing solid technical support for its mission of "Creating Aesthetic Architecture."
