What Tools Are Needed for Hoisting Large-Size UHPC Curtain Wall Panels?

Hoisting large-size UHPC curtain wall panels (single panel area ＞6㎡ or weight ＞500kg) requires four categories of tools: dedicated cranes, flexible lifting gear, precise positioning tools, and safety protection equipment, to ensure smooth, precise, and safe hoisting. Through customized hoisting plans and BIM simulation, Qinglong has achieved zero hoisting accidents across multiple large-size projects, with installation accuracy ≤±2mm.

1. Core Hoisting Equipment: The Foundation of Load-Bearing and Stability

Hoisting equipment must match the weight and dimensions of large-size panels. Crane types: for single panels weighing 500-1000kg, use a 25-50 ton truck crane; for 1000-2000kg, use a 50-100 ton crawler crane; for extra-large panels (＞2000kg), use a crane of 100 tons or more—for the hoisting of Qinglong's 3-meter-high UHPC sculpture at the Shanghai Astronomy Museum, an 80-ton crawler crane was used. Lifting gear selection: flexible lifting slings (load capacity ≥ 1.5 times the panel weight) or custom lifting beams, with soft pads (thickness ≥30mm) placed at contact points between the lifting gear and panels to avoid scratching the panel surface—Qinglong's custom lifting beams distribute loads to prevent panel deformation. Auxiliary hoisting equipment: aerial work platforms (articulated boom or rail-mounted type) for positioning and fixing at height—Qinglong's articulated boom platforms can adapt to double-curved curtain walls, improving operational flexibility by 40%.

2. Precise Positioning and Safety Protection Tools: Ensuring Accuracy and Safety

Positioning tools ensure installation accuracy, while protection equipment mitigates risks. Positioning tools: laser rangefinders (accuracy ±0.1mm), theodolites, and 3D laser positioning systems calibrate panel positions in real time—Qinglong's 3D positioning system displays deviations simultaneously, achieving installation accuracy ≤±2mm. Safety protection equipment: fall arresters, safety nets, and warning signs; cordon lines are set up in hoisting areas, and workers are equipped with double protection—Qinglong's safety protection equipment complies with the GB 6095-2021 standard, with zero safety accidents. Auxiliary tools: soft crowbars (to avoid damaging panels) and torque wrenches (for fixing accessory bolts)—Qinglong's torque wrenches have an accuracy of ±5N·m, ensuring bolt tightening force meets standards.

3. Qinglong's Customized Hoisting Plans and Project Practices

Addressing the characteristics of large-size panels, Qinglong provides full-process hoisting support. Pre-hoisting preparation: BIM simulates hoisting paths to avoid obstacles, and special plans (including emergency measures) are developed—for Qinglong's 12㎡ extra-large translucent panel at Shanghai New World Plaza, BIM simulation optimized the hoisting path, improving efficiency by 30%. Hoisting process control: cranes lift at a constant speed (≤0.5m/s), with dedicated commanders (holding valid certificates), and standing under panels is prohibited—Qinglong's hoisting commanders all have over 5 years of experience in hoisting large-size panels. Post-hoisting fixing: panels are temporarily fixed immediately after positioning, followed by permanent fixing, with temporary fixing load capacity ≥ 1.2 times the panel weight—Qinglong uses double-point support for temporary fixing to ensure no swaying. Project case: in the Shanghai Astronomy Museum public art project, a single UHPC sculpture weighing over 700kg was hoisted using an 80-ton crawler crane plus a custom lifting beam, with installation accuracy ≤±1.5mm, perfectly presenting the design form.
