The turntable structure is an important part of the aerial work platform, which mainly realizes the platform loading and rotating function.
[0046] The existing turntable joint is usually welded with two webs through the bottom plate to form, in order to meet the strength requirement, the web is usually thick, and a plurality of rib plates are welded between the two webs and the bottom plate for reinforcement. However, the inventor found that in order to ensure the welding quality of the turntable, it is necessary to open a large size groove on the web and the bottom plate, which has great difficulty in processing and manufacturing, large welding amount, thick structure, resulting in increased manufacturing cost; the web is a single plate structure, the strength and buckling stability are low, and there is a certain safety hazard.

[0050] Specifically, the first box body assembly 20 comprises a first main plate 21, a first front reinforcing plate 22 and a first rear reinforcing plate 23 arranged on the bottom plate 10, the first main plate 21 has a first front end 211 and a first rear end 212, and the first front reinforcing plate 22 and the first rear reinforcing plate 23 are located on opposite sides of the first main plate 21; one end of the first front reinforcing plate 22 away from the first front end 211 is bent towards the first main plate 21 and connected with the first main plate 21; one end of the first rear reinforcing plate 23 away from the first rear end 212 is bent towards the first main plate 21 and connected with the first main plate 21.

[0065] It should be noted that in this embodiment, the first main board body 213 is integrally formed with the first bent edge 214 and the second bent edge 215, and the second main board body 313 is integrally formed with the third bent edge 314 and the fourth bent edge 315. That is, the first bent edge 214 and the second bent edge 215 are formed by bending both sides of the first main board body 213 towards the same side, while the third bent edge 314 and the fourth bent edge 315 are formed by bending both sides of the second main board body 313 towards the same side.
