What Factors Should Be Considered in the Lifting Plan for Super-Large GRC Shapes?

Hoisting of super-large GRC shapes (weight >5t, dimensions >8m) requires comprehensive calculation of structural strength, lifting point layout, and wind load effects. Drawing on experience from multiple landmark projects, Qinglong Group holds that hoisting plans must meet three key requirements: strength, stability, and precision.

Structural strength verification ensures safety. Hoisting stress is kept below 30% of the material's tensile strength. In the Hainan International Convention and Exhibition Center project, hoisting simulation was carried out on roof units weighing up to 12t to optimize lifting point positions. Specialized lifting fixtures ensure uniform load distribution and prevent local damage.

Stability control prevents overturning. Hoisting wind speed is limited to ≤8m/s, and wind-resistant ropes are installed. The center of gravity is precisely calculated, with tilt angle ≤3°. When multiple cranes perform synchronized lifting, the synchronization error is ≤5%. Through scientific planning, hoisting is ensured to be safe and efficient.
