The components of the platform container (platform box) mainly include a chassis for loading and an end structure connected to both ends of the chassis. According to the different connection methods between the end structure and the bottom frame, it can be divided into fixed-end bench boxes with fixed connection between the end structure and the bottom frame and folding bench boxes with hinged connections between the end structure and the bottom frame. Rack boxes are commonly known as folding boxes in the industry.

One application of dolly boxes is for transport vehicles. In order to facilitate the loading and unloading of vehicles, at present, there are usually two types of frame box end structures used for transporting vehicles. One, as shown in Figure 1, makes the end of the underframe 10 into a slope shape, and there is no gap between the corner posts 11. The end wall structure is set. Although this technical solution is convenient for loading and unloading of the car body, the slope-like setting at the end of the underframe will easily cause the overall strength of the underframe to weaken. Weak, resulting in weak lateral rigidity of the bench box, which is not conducive to the stacking of the box. Its two as shown in Figure 2, adopt folding box, it has complete underframe 10, is fixedly connected with end wall 12 between the corner post 11 of its end structure, when loading and unloading vehicles, the movable hinge plate 14 of corner post 11 bottom and The hinge connection between the fixed hinge plates 13 welded on the side ends of the underframe 10 is disassembled, and then the end structure formed by the corner post 11 and the end wall 12 is placed on the end of the underframe 10 to form a slope for vehicle loading and unloading operations , this technical solution needs to dismantle the hinges when the vehicle is loaded and unloaded, put the end wall structure down and support it obliquely at the end of the chassis. After the vehicle is loaded and unloaded, the end wall structure needs to be restored. The operation is cumbersome and labor-intensive. Only the operator can complete it, it is difficult to use, and the work efficiency is low.
