Lifting Tool Selection and Safety Standards for Large-Size UHPC Curtain Wall Panels

The hoisting of large-size UHPC curtain wall panels (single panels exceeding 5㎡ in area or 500kg in weight) is a core challenge in construction and installation, and tool selection directly affects construction safety and installation precision. Qinglong Group, an enterprise that has undertaken numerous super-large component projects, has drawn on 28 years of construction experience to develop a set of scientific standards for hoisting tool selection and safe operation.

I. Core Requirements of Large-Size UHPC Curtain Wall Panels for Hoisting Tools Hoisting tools for large-size UHPC curtain wall panels must meet three core conditions: sufficient load-bearing capacity, a stable force-bearing structure, and precise maneuverability. The load-bearing capacity should reserve a safety factor of more than 1.5 times to prevent accidents caused by sudden loads; the force-bearing structure should be evenly distributed to prevent localized compression damage to UHPC panels; maneuverability requires fine-adjustment functionality to ensure installation alignment precision. In addition, tools must be corrosion-resistant and rust-proof to adapt to outdoor construction environments.

II. Mainstream Hoisting Tool Types and Applicable Scenarios Currently, common hoisting tools for large-size UHPC curtain wall panels fall into three categories: vacuum suction cup lifters, truss-type lifters, and dedicated spreader beams. Vacuum suction cup lifters are suitable for large flat panels with smooth surfaces; in the Shanghai Astronomy Museum public art project, Qinglong used a vacuum lifter with 16 linked suction cups to successfully hoist UHPC sculpture components over 3 meters in size. Truss-type lifters suit irregular or hollow UHPC panels, such as the UHPC hollow panels of the Ouargla Hotel in Algeria (each weighing over 700kg), where multi-point force distribution through the truss prevents component deformation. Dedicated spreader beams target extra-long and extra-wide components; in the Shanghai Century Plaza renovation project, they were used to hoist a super-large 3245*3530mm UHPC wood-effect translucent panel, ensuring a stable hoisting process.

III. Qinglong's Hoisting Safety Standards and Innovative Practices As an enterprise holding professional contracting qualifications for building curtain wall engineering, Qinglong has established stringent hoisting safety standards. Before hoisting, tool load testing and panel stress calculations must be performed, with cordoned-off areas and dedicated on-site commanders; during hoisting, BIM technology is used to monitor alignment precision in real time, keeping deviations within ±2mm. In the Shenzhen Longhua Xiangshan Science and Technology Park project, Qinglong innovatively adopted a "mid-air fine adjustment + ground guidance" hoisting technique, combined with custom lifting fixtures, improving the installation efficiency of large-size UHPC curtain wall panels by 40%. In addition, Qinglong emphasizes the daily maintenance and calibration of hoisting tools to ensure that every piece of equipment remains in optimal working condition.

The hoisting of large-size UHPC curtain wall panels relies on professional tools and scientific standards; choosing a supplier with engineering experience is key to safety assurance. With 28 years of construction and installation experience, Qinglong Group maintains full control throughout the process—from tool selection and scheme design to on-site execution—and has completed the hoisting of thousands of large-size UHPC components with zero safety accidents. Professional hoisting plans and stringent safety standards are the core of achieving flawless installation of large-size UHPC curtain walls.
