Problems solved by technology
[0002] At present, the spare tire lifting devices used in China are mostly chain-type or steel pipe-welded trailer-type structures. In particular, the cargo box of the truck has no tailgate, and the spare tire disassembly opening is exposed, and the interface is simple, which is often inserted by ordinary tools. The spare tire can be stolen; in order to solve this problem, some automobile manufacturers have to padlock the chain of the spare tire lifting device. This anti-theft method not only makes the spare tire assembly complicated, but also costs a lot, so it is not used. on most trucks
