Lifting Equipment Requirements for Installing Large Double-Curved GRC Panels: Qinglong GRC Technical Standard for Hoisting Large Components

Large-sized double-curved GRC panels (panel area ≥10㎡, weight ≥2t) require special lifting equipment for installation, with lifting capacity ≥5t, lifting height ≥30m, and working radius ≥15m. The equipment must have a micro-movement function (speed ≤0.5m/min), three-dimensional precise positioning capability (positioning accuracy ±10mm), and be equipped with a vacuum lifting system (single suction cup adhesion force ≥2t). BIM is used to simulate the hoisting process and optimize the layout of lifting points to ensure hoisting safety.

Specific equipment configuration: select a truck crane (QY25K5-1) or tower crane (TC7035) based on component dimensions, equipped with special lifting frames (safety factor ≥6) and vacuum suction cups (adhesion force safety factor ≥4). In a cultural center project, the largest double-curved panel measured 6m×3m and weighed 3.5t; a 130t truck crane combined with a vacuum lifting tool successfully completed the installation with a positioning accuracy of ±5mm. Qinglong GRC professional hoisting solutions ensure the safe placement of large components.

Lifting Equipment Selection

Lifting capacity ≥1.5 times the component weight; working radius covering the entire work area; lifting height accounting for safety distance; equipment must have micro-movement function and precise positioning capability. Scientific selection is the foundation of safety.

Lifting Tool System Design

Number of vacuum suction cups ≥4, evenly arranged; lifting frame with sufficient rigidity, deformation ≤L/500; rigging safety factor ≥6, inspected regularly; anti-detachment devices installed for double protection. Professional lifting tools guarantee safety.

Hoisting Process Control

Lifting points determined through calculation, avoiding damage zones; hoisting speed controlled for smooth, uniform movement; in-air attitude adjustment to avoid collisions; placement precision control with fine adjustments. Refined craftsmanship ensures quality.

Safety Monitoring Measures

Real-time weight monitoring with overload alarms; wind speed monitoring, stopping operations when exceeding force level 6; video surveillance with full coverage and no blind spots; emergency plans for rapid response. Comprehensive monitoring ensures safety.

Hoisting large components requires professional solutions. Qinglong GRC's complete system ensures safe and efficient operations.
