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

Hoisting large-size UHPC curtain wall panels (typically referring to panels with an area >6㎡ or length >4m) requires a systematic approach of "specialized lifting equipment, balanced load distribution, and flexible protection." Core tools include vacuum suction cup lifters (for flat panels), spreader beams (for irregular panels), soft lifting slings, and anti-collision corner protectors. During the 120,000-square-meter roof construction at the Hainan International Convention and Exhibition Center, Qinglong Group custom-developed vacuum suction cup lifters with pressure self-locking functions (≥4 suction cups, vacuum degree ≥-80kPa) and adjustable steel spreader beams for double-curved UHPC panels measuring up to 6m×2.5m and weighing approximately 600kg, combined with high-strength nylon slings (width ≥150mm), achieving efficient operations of 150 panels hoisted per day with a panel corner damage rate controlled below 0.1%. Safe and efficient hoisting is a key link in ensuring the quality and progress of large panel installation.

Vacuum Suction Cup Lifters Are the Ideal Choice for Damage-Free Hoisting

Their principle is to generate negative pressure through a vacuum pump, allowing the suction cups to firmly adhere to the panel surface with uniform contact pressure, without causing squeezing damage to panel edges. The suction cups we use are fitted with rubber pads to accommodate slight curves, and feature a pressure alarm function that automatically alerts when the vacuum degree is insufficient, ensuring safety.

Spreader Beams and Slings Guarantee Force System Balance

For irregular panels or panels with asymmetric centers of gravity, spreader beams are needed to convert lifting forces into balanced multi-point loading. Slings must be wide enough to avoid concentrated stress. We calculate lifting point positions based on each panel's center of gravity and customize dedicated lifting frames.

Refined Operational Procedures Are the Core of Safety

Trial lifts are conducted before hoisting to check balance; lifting and moving must be smooth to avoid swinging; dedicated personnel direct positioning, using crowbars for fine adjustments. We develop detailed hoisting plans and provide specialized training for operators.

As the saying goes, "To do a good job, one must first sharpen one's tools." Through advanced hoisting equipment and rigorous management, Qinglong Group ensures large panel installation is handled with ease.
