Key points and cycles for daily maintenance of crossbeam shelves The maintenance core of crossbeam shelves lies in "preventing loosening, collision, and rust", and a regular maintenance plan needs to be developed. Firstly, check the connection buckle between the crossbeam and the column every quarter to see if it is loose, and whether the safety pin is missing. If the buckle is found to be loose, it should be tightened in a timely manner with a wrench. If the safety pin is missing, it should be immediately replenished to prevent the crossbeam from falling off; Secondly, check the shelf columns for collision marks every month, especially in areas with frequent forklift operations. Anti collision foot guards or guardrails can be installed to reduce collision damage. If the columns show slight deformation, they need to be corrected in a timely manner, and if they are severely deformed, they need to be replaced; Finally, check the corrosion of steel every six months, especially for shelves in damp, acidic and alkaline environments. Regularly clean the surface dust and oil stains, and remove rust from the corroded areas (by sanding with sandpaper) before applying anti-corrosion paint to extend their service life. In addition, the load-bearing limit should be prominently marked on the shelves, and overweight storage is prohibited to avoid structural damage caused by long-term overload.
