What Factors Should Be Considered in the Hoisting Plan for Super-Large GRC Shapes? Safety System Design for Lifting and Installation of Heavy Components

The hoisting of super-large GRC shapes (single piece weight ≥5 tons or dimensions ≥6 meters) is a high-risk operation, requiring comprehensive evaluation of component strength, lifting point design, lifting equipment, and safety contingency plans. In the hoisting of large roof panels at the Hainan International Convention and Exhibition Center, Qinglong Group verified hoisting stresses through finite element analysis (≤50% of design stress), dedicated lifting fixtures (safety factor ≥4), and BIM simulation, achieving the safe installation of GRC panels weighing 8 tons per piece with an area of 20 square meters, with errors controlled within ±3mm.

Lifting point design is critical; positions and quantities are determined through calculation, with local reinforcement to avoid stress concentration. Lifting equipment selection must match component weight and site conditions, and multi-crane tandem lifting requires synchronized control. Safety measures include wind speed monitoring (lifting suspended when wind force exceeds level 6), trial hoisting verification, and emergency contingency plans. Through scientific management, Qinglong Group has achieved a zero accident rate in large-scale hoisting operations. Comprehensive plans ensure the smooth progress of major projects.
