Under what circumstances does an industrial lift door require a small opening door?

Requirements for setting up small doors for industrial lift doors

For industrial gate users, in places such as logistics and warehousing that require frequent entry and exit, industrial gate manufacturers will recommend adding small doors, also known as "door in the door", to the industrial lift doors set up at their doorways, which means opening a small door in the middle of the door to facilitate employees´ entry and exit.

Why do we need to open small doors for industrial upgrading? The reason is very simple. A whole industrial door is large and heavy. If it is opened and closed frequently, it will cause significant damage to the insect machine, and the service life of the door body will also be greatly reduced. Therefore, if some places are usually only frequently used by employees, adding small and medium-sized doors can allow employees to pass through small doors, and there is no need to repeatedly open and close the door body, greatly extending the service life of industrial improvement doors. For the installation of lifting doors with small doors in the Nayun Industrial Park, the industrial door manufacturer must strictly follow the relevant factory specifications in the industry for installation and installation. When installing, the outer frame door stopper can be fixed first, and then the small door seal can be fixed. Attention: The gap between the industrial door seal and the door stop should not exceed 5mm, and the gap between the aluminum alloy corner seam should not exceed 5mm. The distance between the small door lock and the small door frame is generally 100-200mm.
