What Equipment Is Needed to Hoist Large-Size UHPC Curtain Wall Panels: Key Equipment and Technical Points Explained

Tools for Lifting Large-Size UHPC Curtain Wall Panels: Key Equipment and Technical Points Explained

In the field of contemporary architectural curtain walls, ultra-high performance concrete (UHPC) has become the preferred material for landmark building skins thanks to its outstanding mechanical properties and design expressiveness. However, the lifting of large-size UHPC curtain wall panels is both a technical challenge and a safety test, requiring professional equipment configuration and scientific process control to achieve "millimeter-level" installation accuracy. As an industry-leading enterprise with 28 years of deep expertise in the UHPC/GRC/GRG/GRP field, Qinglong Group has systematically summarized the key equipment and technical points for lifting large-size UHPC curtain wall panels based on thousands of engineering projects, providing professional solutions for the industry.

I. Core Equipment Systems for Lifting UHPC Curtain Wall Panels

Lifting large-size UHPC curtain wall panels (usually referring to panels with a single-piece area of ≥5㎡ and a weight of 300-800kg) requires building a "trinity" equipment system. The main lifting equipment of choice is a 25-50 ton truck crane or tower crane, equipped with an extra-long boom (30-50m) and a precision weighing system to ensure the lifting radius covers the entire working surface. For irregular curved components, a hydraulic lifting platform with 360° rotation capability must be used, combined with a vacuum suction cup lifting device (suction force ≥1.2 times the component weight) to achieve non-destructive gripping. Auxiliary equipment includes laser line projectors (accuracy ±1mm), 3D scanning positioning systems (real-time deviation monitoring), and special transport racks (with shock-absorbing buffers), forming full-process safety assurance from factory to installation surface.

II. Analysis of Technical Points for Lifting UHPC Curtain Wall Panels

1. Technical preparation before lifting: Complete BIM model pre-assembly simulation, determine lifting point positions (4-6 lifting points per panel, symmetrically distributed), and perform pre-loading tests on UHPC components (loading to 1.5 times the design load). Qinglong Group's original "double insurance" lifting device design combines traditional steel lifting lugs with concealed built-in lifting points, ensuring lifting strength while avoiding any impact on the building's appearance.

2. On-site installation process: Adopt the "staged lifting method", first hoisting the component to the installation height with the main crane, then performing fine-tuning alignment with auxiliary lifting equipment. During installation, a total station is used for real-time coordinate monitoring to ensure planar position deviation ≤3mm and verticality deviation ≤2mm/m. For super high-rise projects, a dedicated wind-resistant guy cable system must be installed, and operations must be suspended immediately when wind speed exceeds 10m/s.

3. Quality control system: After each UHPC curtain wall panel is installed, torque wrench testing (bolt preload meeting design values), structural sealant integrity inspection (curing degree ≥95%), and water spray testing (simulating 1 hour of heavy rain without leakage) must be carried out. The full-process traceability system established by Qinglong records the complete lifecycle data of component production, transportation, and installation through RFID chips.

III. Comparison of Lifting Processes Between UHPC and Traditional Curtain Wall Materials

Compared with GRC curtain wall panels (weighing approximately 150-300kg/㎡), UHPC, with its higher density (2400-2600kg/m³), places higher demands on lifting equipment, but its excellent flexural strength (≥20MPa) allows the number of lifting points to be reduced. Compared with stone curtain walls, UHPC curtain wall panel lifting efficiency is 40% higher, and no additional back-bolt reinforcement is required. In the Century Plaza renovation project on Nanjing East Road, Qinglong adopted a customized lifting scheme and successfully controlled the installation accuracy of light-transmitting UHPC curtain wall panels weighing 580kg each within 1.5mm, setting a record among similar projects.

As a national high-tech enterprise and a participant in formulating UHPC industry standards, Qinglong Group has always upheld the mission of "creating beautiful architecture", integrating 28 years of experience in detailed design, manufacturing, and construction installation into every detail. Whether it is the hyperbolic UHPC curtain wall of a grand theater or the super-large exterior panels of a commercial complex, Qinglong can provide full-chain services from material R&D to lifting operation and maintenance. Choose Qinglong for professionalism and peace of mind, and let every UHPC curtain wall panel become a perfect fusion of architectural aesthetics and engineering safety.
