What Tools Are Required for Lifting Oversized UHPC Curtain Wall Panels: Key Lifting Equipment and Technical Points Explained

What Tools Are Needed for Hoisting Large-Size UHPC Curtain Wall Panels? Analysis of Key Hoisting Equipment and Technical Points

In the field of modern architectural decoration, UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and outstanding molding capability, has become an ideal choice for the curtain wall decoration of large public buildings and landmark projects. As architectural design grows increasingly innovative, large-size UHPC curtain wall panels are being applied ever more widely, and their hoisting, as a critical construction step, directly affects project quality, safety, and efficiency. As an industry leader with 28 years of full-chain experience in the detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group draws on the practice of hundreds of large projects to systematically explain the key equipment and technical points for hoisting large-size UHPC curtain wall panels.

I. Selection of Core Equipment for Hoisting Large-Size UHPC Curtain Wall Panels

Large-size UHPC curtain wall panels typically weigh up to several hundred kilograms each, with some specially shaped components even exceeding one ton, and installation precision requirements are extremely high (millimeter-level tolerances). Therefore, the selection of hoisting equipment must balance load capacity, operational flexibility, and safety.

1. **Lifting Equipment: Matching the Main Hoisting Machinery to the Scenario** For different building heights and site conditions, commonly used lifting equipment includes truck cranes, tower cranes, and crawler cranes. Truck cranes are suitable for mid- and low-rise buildings or projects with open sites, offering the advantages of easy mobility and high relocation efficiency; tower cranes are suitable for super high-rise buildings and can perform 360-degree all-around operations to support the orderly installation of UHPC curtain wall panels; crawler cranes, with their ultra-strong load capacity, are the first choice for hoisting overweight, oversized, and specially shaped UHPC components, performing particularly well on complex terrain. In the Nanjing East Road Century Plaza renovation project, Qinglong Group used a 250-ton crawler crane to precisely hoist light-transmitting UHPC curtain wall panels weighing up to 1.2 tons each, ensuring the perfect joining of the curved forms.

2. **Lifting Fixtures and Rigging: The "Lifeline" of Component Safety** Hoisting UHPC curtain wall panels requires dedicated lifting fixtures, with common types including four-point balanced spreaders, vacuum suction cup lifters, and custom hoisting frames. By adjusting the lifting point positions, four-point balanced spreaders can effectively prevent deformation caused by center-of-gravity deviation during lifting; vacuum suction cup lifters are suitable for UHPC panels with flat surfaces and enable damage-free hoisting, making them especially suitable for protecting delicate decorative finishes; for UHPC components with complex shapes such as double-curved surfaces and openwork patterns, Qinglong Group uses BIM technology to pre-fabricate dedicated hoisting frames to ensure uniform distribution of hoisting forces. For example, in the Dongguan Women and Children's Activity Center project, custom steel brackets combined with high-strength fiber lifting slings were used to successfully and safely hoist specially shaped GRC/UHPC composite curtain wall panels.

3. **Auxiliary Equipment: Key to Improving Precision and Efficiency** To guarantee installation precision, measuring equipment such as total stations and laser line projectors must be equipped to monitor component positions in real time; for work at height, electric hoists and hydraulic lifting platforms can assist in fine-tuning component orientation; in addition, safety auxiliary tools such as wind-resistant cables and buffer pads are also indispensable. Especially in environments where wind force exceeds level 6, components must be secured with multi-directional cables to prevent swaying from causing collisions.

II. Technical Points and Full-Process Control for Hoisting Large-Size UHPC Curtain Wall Panels

The success of hoisting operations depends not only on equipment but also on sound technical plans and strict process management. Based on its full-chain advantages spanning "detailed design - manufacturing - construction and installation," Qinglong Group has developed a standardized hoisting technical system.

1. **Early-Stage Detailed Design: Avoiding Hoisting Risks at the Source** During the design phase, Qinglong's technical team simulates the hoisting process through BIM modeling to optimize lifting point settings and load paths, ensuring that the structural strength of the UHPC curtain wall panels meets hoisting requirements. At the same time, a detailed hoisting plan is formulated in line with actual project conditions, covering equipment selection, lifting fixture configuration, emergency plans, and more, and the feasibility of the plan is verified with structural load calculation software to prevent construction hazards caused by design defects.

2. **Component Pre-Treatment: Ensuring Hoisting Stability** Before leaving the factory, UHPC curtain wall panels must have their hoisting embedded parts precisely installed, and the material and welding strength of the embedded parts must meet specification requirements (tensile strength ≥300MPa). Meanwhile, components are numbered and labeled with their weights to facilitate hoisting sequencing on site; for large-size components, temporary reinforcement measures must also be added in non-load-bearing areas to prevent deformation during transport and hoisting.

3. **On-Site Hoisting Techniques: Refined Operations for Safety and Precision** Before hoisting, all equipment must be thoroughly inspected, including crane performance, wear of lifting fixtures, and wire rope tension; lifting follows the "trial lift - adjustment - formal hoisting" procedure, with the trial lift height controlled at 30-50 cm and hoisting proceeding slowly once no abnormalities are confirmed; during installation, component positions are fed back in real time through the measuring equipment, and auxiliary equipment is used for fine-tuning to ensure precise alignment with the installation datum lines. In overseas projects (such as a commercial complex in Malaysia), Qinglong Group used 3D laser scanning technology to keep UHPC curtain wall panel installation errors within ±2mm, far exceeding industry standards.

4. **Safety and Quality Control: Whole-Process Risk Prevention** Warning zones must be set up on site, staffed with dedicated safety officers; hoisting personnel must be certified and strictly follow operating procedures; in extreme weather (such as torrential rain or strong winds), operations must be suspended and components secured. In addition, Qinglong has established a quality traceability system that records data from the entire hoisting process of each component via RFID chips, providing a basis for subsequent maintenance.
