It usually consists of guide rails laid on the ground, several rows of compact shelving and a driving mechanism installed on the outer box of the compact shelving for driving the compact shelving to move on the above-mentioned guide rails. In order to make full use of the space in the archive room, compact shelving is generally very high, so the bottom track of the compact shelving is equipped with a device to prevent it from tipping over.

[0003] Patent publication number CN208160444U describes an anti-tip device for compact shelving systems. The invention comprises a guide rail with a C-shaped cross-section and a stop bar in the middle. An anti-tip plate slidably connects to the rail. The protrusions at each end of the plate insert into cavities at either end of the rail. A groove is defined in the middle of the bottom of the plate to accommodate the stop bar.
