[0004] 2. The lifting lug cutting is easy to hurt the ship body parent material;

[0005] 3. The lifting lug can be reused only 3 times, and the installation of lifting lug material is large;

[0006] 4. The installation position of the lifting lug is fixed, and after installation, it cannot be adjusted, and when there is interference in the installation of the subsection and pipeline, the lifting lug needs to be cut off and installed at other positions, and in the case that the installation of the lifting lug is not balanced, the stress of each point is uneven during the hoisting of the deck subsection, which can easily cause the deformation of the subsection hoisting;

[0007] 5. The installation and welding of the subsection lifting lug need to be equipped with enough construction personnel and resources to complete, and the construction cost is high, and the construction period is long;

[0008] Therefore, the installation of the lifting lug of the subsection hoisting will affect the deformation of the subsection, increase the workload and increase the cost, and in this situation, an earless hoisting device is urgently needed to meet the hoisting construction of the deck subsection, reduce the deformation caused by the installation of the ear of the subsection and the cutting of the ear to hurt the parent material, and reduce the shipbuilding cost and improve the production efficiency.
