[0021] In one embodiment, the mounting bracket assembly 100 can utilize the structure of the chassis beam of the transport vehicle, or the required mounting bracket assembly 100 can be welded by the vehicle itself. Since it is the main load-bearing component of the upper structure, it is required to use at least Q235 carbon steel with rigid strength, otherwise the material may break or deform.

[0022] In one embodiment, such as Figure 2 As shown, the fork tooth fixing assembly 200 includes a fork tooth sleeve 210, a crossbeam 220, and a reinforcing plate 230. Each of the two crossbeams 220 has a first connecting hole 221 on both sides. The two crossbeams 220 are bolted to the inner side of the mounting base assembly 100 through the first connecting holes 221. Each of the two crossbeams 220 has a notch 222 on both sides.
