What Tools Are Needed for Hoisting Large-Size UHPC Curtain Wall Panels? Professional Tool Selection and Application Guide

In the field of modern architectural decoration, UHPC (Ultra-High Performance Concrete) has become the ideal choice for curtain wall systems in high-end projects such as landmark buildings and commercial complexes, thanks to its outstanding mechanical properties and design freedom. However, the hoisting of large-size UHPC curtain wall panels (each typically weighing over 500kg) is both a critical link in project implementation and a core challenge for safety and efficiency. As an industry-leading enterprise with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group has summarized a scientific tool selection and application system based on the practice of hundreds of large projects, providing a professional reference for the industry.

I. Core Tool System for UHPC Curtain Wall Panel Hoisting: From Load-Bearing to Precision Positioning

Hoisting tools for large-size UHPC curtain wall panels must simultaneously meet three core requirements: load-bearing safety, posture adjustment, and precise docking. In benchmark projects such as the Nanjing East Road Century Plaza renovation project and the Dongguan Women and Children's Activity Center, Qinglong Group has developed a three-tier tool configuration plan with "lifting equipment as the core, specialized lifting devices as the key, and auxiliary tools as the guarantee."

The selection of lifting equipment should be comprehensively determined based on panel weight, installation height, and site conditions. For UHPC curtain wall panels weighing 300-800kg each, 25-50 ton truck cranes or tower cranes are typically used, whose hydraulic telescopic booms and 360-degree rotation functions can meet high-altitude work requirements; extra-large components (such as special-shaped curved UHPC cladding panels) require crawler cranes of 100 tons or more, combined with super-lift devices to enhance stability. It is worth noting that all lifting equipment must pass third-party inspection, and operators must hold special operation certificates—this is an important guarantee of Qinglong's zero-accident record over 28 years of construction.

II. Specialized Lifting Devices: The "Safety Lock" for UHPC Curtain Wall Panel Hoisting

Lifting devices are the key link connecting lifting equipment and UHPC curtain wall panels, and their design directly affects hoisting safety and component protection. Based on the characteristics of UHPC materials, Qinglong Group has customized and developed three types of specialized lifting devices:

1. **Four-point balance lifting device**: Achieves horizontal posture control of curtain wall panels through adjustable steel wire rope lengths, suitable for flat or slightly curved UHPC panels. In a commercial complex project in Guangzhou, this device successfully solved the horizontal hoisting challenge of a 12-meter-long UHPC sunshade panel; 2. **Vacuum suction cup lifting device**: Uses negative pressure to attach to the curtain wall panel surface, avoiding the stress damage caused to panels by traditional lifting lugs; especially suitable for ultra-thin (thickness ≤30mm) UHPC components or those with delicate surface textures, such as the light-transmitting UHPC curtain wall panels in the Nanjing East Road project which adopted this solution; 3. **Custom truss lifting device**: For special-shaped UHPC panels such as hyperbolic curved and hollow-out designs, stress distribution is analyzed through BIM modeling to design specialized truss structures, ensuring that components do not deform during hoisting. In an airport project in Saudi Arabia, Qinglong used this device to complete the installation of a 1.2-ton special-shaped UHPC canopy panel.

III. Auxiliary Tools: The "Invisible Helpers" for Improving Efficiency and Precision

Beyond core lifting equipment and devices, the configuration of auxiliary tools is key to achieving precision installation. Qinglong Group's standard equipment for construction includes the following tools: 3D laser positioning instruments (with errors controlled within ±2mm), hydraulic levelers (for fine-tuning curtain wall panel angles), and temporary fixing brackets (to prevent components from swinging during hoisting). At the Nanning production base in Guangxi, all UHPC curtain wall panels undergo simulated hoisting tests before leaving the factory. Combined with these auxiliary tools, on-site installation efficiency can be improved by more than 40%.

IV. Full-Chain Guarantee: A Coordinated Tool System from Design to Maintenance

As a national high-tech enterprise integrating detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group emphasizes that "tool selection must be deeply coordinated with the entire process." In the design phase, BIM technology is used to simulate hoisting paths and plan lifting point positions and tool parameters in advance; in the production stage, RFID chip implantation technology is adopted to record key data such as the weight and center of gravity of each curtain wall panel, providing a precise basis for hoisting tool selection; during construction, in accordance with the requirements of the "Grade II Professional Contracting for Building Curtain Wall Engineering" qualification, a system of regular tool inspection and maintenance is established; in the after-sales stage, specialized testing tools are provided for long-term monitoring of hoisting joints. This full-chain thinking is precisely the core competitiveness that enables Qinglong to undertake overseas projects in Malaysia, Australia, and beyond.

The selection of hoisting tools for large-size UHPC curtain wall panels is by no means a simple accumulation of equipment, but a comprehensive embodiment of technical experience, engineering practice, and safety standards. Based on 28 years of industry experience, Qinglong Group provides a solid guarantee for the safe and efficient construction of UHPC curtain wall systems through its "professional tools + scientific management + full-process service" model. In the future, as UHPC materials are applied in more complex buildings, innovation and standardization of tool technology will become important topics for industry development. Qinglong will continue to leverage its advantages as a "National Specialized and Sophisticated Enterprise" and a "Participant in Industry Standard Development" to promote the iterative upgrading of UHPC hoisting technology and contribute to the mission of "Creating Beautiful Architecture."
