[0002] Currently, heavy-duty transfer in the crane market is becoming increasingly common. Working conditions such as excessive driving speed, poor road conditions, and long distances may damage the tires. The weight of the spare tire of heavy machinery is generally above 100KG. When the tire is fixed below the vehicle and the side protection is arranged on the side, it is very difficult to disassemble and assemble. Moreover, due to reasons such as space and the large volume of the spare tire itself, the components around the spare tire cannot be quickly repaired, and the spare tire and side protection may need to be removed first during maintenance.

[0003] In the prior art, the spare tire is arranged below the vehicle and inside the side protection. The side protection is fixed and cannot be flipped. The spare tire is fixed on the spare tire bracket. When installing the spare tire, the spare tire needs to be moved below the spare tire bracket, and the rotating operating rod pulls the spare tire up to the designated position through the lifting mechanism. When disassembling, the spare tire is lowered to the ground through the lifting mechanism, and then the spare tire is pulled out for use.

[0004] The prior art has the following defects: 1. The side protection cannot be adjusted. When maintenance personnel enter the vehicle to work, the space is narrow, and the humanization is relatively low; 2. The space around the spare tire is narrow and the volume of the spare tire itself is large. The spare tire can only move vertically up and down, and there is no space to repair the components near the spare tire; 3. The disassembly and assembly efficiency of the spare tire is relatively low. When assembling, the spare tire needs to be moved below the spare tire bracket, or when disassembling, the spare tire needs to be pulled out to the outside of the vehicle. The operation is laborious, and the efficiency of using the operating rod to rotate for disassembly and assembly of the spare tire is relatively low. Summary of the Invention
