The chassis front end (lower section for being located at chamber door) for hiding container is provided with threshold, and the upper surface of threshold is concordant with the upper surface of chassis,
For the ease of the circulation of cold air in frozen products insulated container, existing frozen products insulated container is needed on the upper surface of chassis laying T-shaped floor,
I other words frozen products insulated container internal ground height has a larger difference in height with threshold upper surface, typically at least T-shaped
The thickness of plate, when carrying out handling goods to frozen products insulated container, because the difference in height is larger so that fork truck is entering refrigeration packaging
Resistance in box body is larger, and operating process is complex, it will usually due to the corner post of poorly operated collision doorframe side.
In current operating process, although skewback can be increased between the front end face on threshold and T-shaped floor to realize
Buffering, but it needs to set accessory in addition, the opening position such as between the front end on T-shaped floor and threshold sets buffering skewback,
Then can be in cold chain transportation process, the air port of front edge of board, influences cold storage effect with covering T-shaped, and therefore, the buffering as accessory is oblique
Block can not carry out logistics transportation with frozen products insulated container, using upper, however it remains certain limitation.
