The automatic multi-layer filing cabinets can be further divided into external motor and internal motor types (with straight-up-and-down doors) based on the motor's placement.
【Automatic Floor Selection File Cabinet】The externally mounted motorized floor selection cabinet comes with a workbench, optimizing the internal space utilization. The workbench facilitates the organization of documents by administrators, and more than 90% of such floor selection cabinets are used in the market.

The built-in motor selection cabinets place the motor at the bottom of the cabinet, occupying the space of one storage bin. This results in a slightly reduced storage capacity per cabinet and lacks a work surface for staff to organize documents. However, in a limited storage area, it allows for an increased number of filing cabinets.
