A method for lifting and turning steel structures without welded lifting lugs involves CNC-controlled or manual drilling of permanent openings in the vertical plates or webs of T-beams of the steel structure, with the positions and number matching the crane's lifting points. Permanent reinforcing plates are welded around these openings for reinforcement. The opening dimensions must meet the pin assembly requirements of the turning connection device, and the reinforcing plate dimensions must meet the assembly requirements of the lifting and turning device and comply with safety regulations. After the tooling is connected to the permanent openings in the structure, during lifting and turning at 180°, the load-bearing connecting plate and the free edge of the T-beam are in line contact, facilitating the bearing of line load pressure and thus optimizing the overall stress distribution of the tooling. This method completely eliminates lengthy and high-risk additional processes such as lifting lug installation, flaw detection, cutting, grinding, and base material repair. Preparation time before lifting and turning and post-turning processing time are reduced by more than 80%, significantly improving production line efficiency.
