Tools Required for Lifting Large UHPC Curtain Wall Panels and Key Technical Points Explained

Large-Size UHPC Curtain Wall Panel Hoisting: From Tool Selection to Technical Control, 28 Years of Industry Experience Safeguarding Safety and Precision

As modern architectural aesthetics pursue super-large spans and irregular curved surfaces, UHPC (Ultra-High Performance Concrete) curtain wall panels have become the new favorite "skin" of landmark buildings thanks to their ultra-high strength, excellent durability, and design freedom. However, the hoisting of large-size UHPC curtain wall panels (typically weighing several hundred kilograms each and exceeding 6 meters in size) is both a critical link in project implementation and a dual test of safety and precision. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on its full-chain service experience to systematically analyze the core tools and key technical points of large-size UHPC curtain wall panel hoisting.

I. Hoisting Tools for Large-Size UHPC Curtain Wall Panels: The Cornerstone of Safety and Efficiency

The selection of hoisting tools directly affects operational safety and installation precision, and must be comprehensively configured according to the weight, dimensions, and installation environment of the UHPC curtain wall panels:

1. Lifting Equipment: The "Power Core" of Hoisting Operations
For large-size UHPC curtain wall panels, 25-200 ton truck cranes or crawler cranes are typically used, equipped with booms that rotate 360 degrees to meet operational needs at different heights and radii. For super high-rise buildings or complex sites, tower cranes and construction hoists can work in coordination to ensure hoisting stability. In component hoisting at its Nanning production base, Qinglong once achieved the precise positioning of a single 8-meter-long UHPC curtain wall panel through a combination of custom lifting fixtures and a 200-ton crawler crane.

2. Specialized Lifting Fixtures: The "Guardian" of UHPC Panels
Given the brittle nature of UHPC materials, specialized lifting clamps or slings must be used. Four-point balanced lifting fixtures are recommended, which adjust the spacing between lifting points to lift panels horizontally, avoiding panel cracking caused by stress concentration. For irregular curved UHPC curtain wall panels, curved lifting fixtures or vacuum suction cups can be customized to ensure perfect conformity with the panel's curved surface. In the Nanjing East Road Century Plaza renovation project that Qinglong participated in, translucent UHPC curtain wall panels were hoisted with zero damage using a combination of vacuum suction cups and balanced lifting fixtures.

3. Auxiliary Tools: The "Detail Guarantee" of Precision Control
This includes laser line projectors (for positioning axes and elevations), torque wrenches (for tightening connecting bolts), and temporary fixing supports (to prevent panel swaying). During the detailed design stage, Qinglong simultaneously provides hoisting auxiliary tool plans, such as custom temporary support frames, to ensure panels maintain a stable posture during installation.

II. Key Technical Points of Large-Size UHPC Curtain Wall Panel Hoisting: Full-Process Control from Design to Construction

1. Detailed Design First: "Source Control" of the Hoisting Plan
During the construction drawing design stage, hoisting condition simulations must be conducted based on the weight, dimensions, and installation positions of the UHPC curtain wall panels (e.g., using BIM technology to simulate boom working radius and panel lifting paths), clarifying lifting point positions, hoisting sequences, and emergency plans. As a national-level high-tech enterprise with a provincial engineering technology center, Qinglong can optimize lifting point layouts through parametric design, ensuring balanced load distribution on each UHPC curtain wall panel.

2. Pre-Hoisting Preparation: "Dual Verification" of Safety and Precision
Before operations, load tests must be conducted on lifting equipment, checking the wear condition of lifting fixtures and the strength of connection nodes. At the same time, three-dimensional scanning of the installation substrate generates an as-built model, which is compared with the design model to correct deviations in advance. In the Dongguan Women and Children's Activity Center project, Qinglong combined BIM technology with on-site scanning to control installation errors within ±2mm, far exceeding industry standards.

3. Hoisting Process Control: Dynamic Adjustment and Precise Positioning
During lifting, maintain a uniform and steady speed, avoiding sudden stops and turns. When approaching the installation position, use guy ropes to assist in adjusting the panel angle, and use laser line projectors to calibrate axes and elevations in real time. For hyperbolic or large-cantilever UHPC curtain wall panels, "aerial docking" technology can be adopted, achieving precise splicing through temporary fixing devices. Qinglong's construction teams are all professionally trained and capable of handling unexpected situations. In strong wind conditions, a wind protection contingency plan can be activated immediately to ensure construction safety.

4. Quality Acceptance and After-Sales Maintenance: A Full Life-Cycle Commitment
After hoisting is completed, bolt torque testing, panel flatness acceptance, and structural adhesive curing monitoring are required. As a supplier integrating "detailed design - manufacturing - construction and installation - after-sales maintenance," Qinglong has established a comprehensive quality traceability system, equipping each UHPC curtain wall panel with a unique identifier and providing up to 15 years of after-sales maintenance service, eliminating customers' worries.

The hoisting of large-size UHPC curtain wall panels is a comprehensive embodiment of technology, experience, and responsibility. As a participant in establishing UHPC/GRC/GRG/GRP industry standards, Qinglong Group has always adhered to the principle of "meticulousness and the pursuit of excellence," providing designers and owners with full-chain solutions from material selection to construction implementation. Whether it is the super-large UHPC curtain walls of landmark buildings or artistic components with complex shapes, Qinglong leverages 28 years of professional expertise to ensure the safety and precision of every hoisting operation, helping to achieve the mission of "creating aesthetically beautiful architecture."
