[0002] In the construction industry, tower cranes are usually needed to improve work efficiency. Depending on the specific usage scenarios, the huge tower cranes often need to be transported to various sites. And precisely because the tower cranes are too large, they need to be disassembled into multiple parts during the transportation process and then grouped for transportation.

[0003] However, in the process of transportation, for the convenience of loading and unloading, the boom sections of the tower crane are often separated and assembled in pairs for loading and transportation, which saves loading space to a certain extent; but this mode of transportation often causes friction and collision between the assembled booms, especially the boom diagonal tie rods, which are likely to be worn during transportation. Minor wear only requires normal repainting, but in case of severe wear, the boom diagonal tie rods need to be cut and replaced on site, and then re-inspected and painted, and this situation is difficult to avoid.
