The circular pipe columns 11 are spaced apart to ensure uniform distribution of connection points and improve connection stability. Each circular pipe column 11 has a flange connecting plate 12 at its end for mating with the flange connecting plate 12 of the middle connecting member 2. Fasteners 4 are used to connect the flange connecting plate 12 on the first lifting member 1 to the flange connecting plate 12 on the middle connecting member 2, and the flange connecting plate 12 on the second lifting member 3 to the flange connecting plate 12 on the middle connecting member 2, so as to firmly connect the first lifting member 1, the middle connecting member 2 and the second lifting member 3 together, ensuring stability and safety during the lifting process. Fasteners 4 are usually high-strength bolts or similar connectors that can withstand large tensile and shear forces. Each fastener 4 passes between two flange connecting plates 12, connecting the first lifting member 1 and the second lifting member 3 to the central connecting member 2 respectively.

The connection of one end of each reinforcing plate 7 to one of the two side walls of the lifting lug 8 and the other end to the connecting pipe 6 forms a stable triangular structure, enhancing the connection strength. The reinforcing plates 7 are typically made of high-strength materials, such as high-strength steel or aluminum alloy, to ensure that they can withstand greater tensile and shear forces.
[0038] Please see Figure 1 In one embodiment, the first lifting member 1 is cylindrical, and both the central connecting member 2 and the second lifting member 3 are annular. The cylindrical shape of the first lifting member 1 provides stable central support, capable of withstanding large vertical loads, and is suitable for connecting lifting equipment (such as cranes). The cylindrical structure ensures even load distribution, improving stability and safety during lifting. The annular central connecting member 2 provides intermediate transition and support, flexibly connecting the first lifting member 1 and the second lifting member 3, adapting to modules of different sizes and shapes. The annular second lifting member 3 allows it to connect to the central connecting member 2 and can also directly connect to the module being lifted, suitable for lifting large modules. In another embodiment, the first lifting member 1 is cubic, and both the central connecting member 2 and the second lifting member 3 are U-shaped, with no restrictions on their shape.
[0039] In one embodiment, a plurality of lifting lugs 8 are radially distributed from the center of the first lifting member 1 to the periphery. This radial distribution of the lifting lugs 8 ensures that the lifting points are evenly distributed across the first lifting member 1, the central connecting member 2, and the second lifting member 3, improving the stability and balance of the lifting operation. The radially distributed lifting lugs 8 also ensure a uniform load distribution during the lifting process, reducing structural deformation or damage caused by uneven stress.
