Do Installation Methods Differ for GRC Components of Different Weights? Lifting Plans and Qinglong Group's Differentiated Construction

GRC components of different weights require differentiated installation designs. Lightweight panels (≤100kg) can be installed manually, while heavy panels (>300kg) require mechanical lifting. The key lies in the precise matching of lifting point design, lifting equipment, and safety measures. In the Hainan International Convention and Exhibition Center project, Qinglong Group customized vacuum suction cup lifting devices (suction force ≥200kg per point) and calculated lifting point positions (≥1/4 of panel length from the edge) for 120,000 square meters of roof panels (each weighing 150-500kg), achieving an installation efficiency of 500m² per day. Scientific installation methods ensure safety and precision while preventing component damage.

Lightweight Component Installation Optimization

Panels weighing ≤100kg are installed manually with simple lifting tools. Qinglong Group trains its installation workers, achieving high efficiency and low cost.

Mechanical Lifting of Heavy Components

Panels weighing >300kg are lifted using tower cranes or truck cranes. Lifting points are verified through finite element analysis, with a safety factor ≥3.

Safety and Precision Control

Operations stop when wind speed exceeds 10m/s, and installation error is ≤±3mm. Qinglong Group maintains a zero-accident safety record.

Differentiated installation enables efficient and safe construction.
