Description

Container chassis

technical field

The utility model relates to the field of containers, in particular to a container bottom frame.

Background technique

For existing containers, in order to facilitate the carrying of goods in the box, the need to set multiple bottom beams (CROSSMEMBER) on the bottom frame has become a fixed pattern, and the bottom beams are arranged densely. Generally, there are more than 15 bottom beams for a 20-foot container, and more than 15 bottom beams for a 40-foot container. There are more than 35 bottom beams, and the installation of the bottom beams is complicated. In addition, most of the common dry cargo container underframes use wooden floors to lay on multiple bottom beams on the underframe, and the wooden floors are fixed on the underframe by fasteners, which not only requires a large amount of wood, which is not conducive to environmental protection, but also due to Under the frequent loading and unloading of forklifts, the wooden floor is easily damaged, thereby shortening its service life and increasing the corresponding maintenance costs. Therefore, it is necessary to conduct research on alternative materials for wooden flooring to solve the problems of wooden flooring.

It is still necessary to lay steel floor on multiple bottom beams and fix it with the chassis by welding or fasteners. However, the assembly method of steel floor is different from that of wooden floor. floor, and the specific gravity of steel materials is relatively heavy, so the current production and assembly efficiency of steel floor containers is low, and the weight is heavier than wooden floor containers.
