After long use, warehouse cages inevitably show damage: cracked welds, broken mesh wires, bent posts, deformed bases. A damaged cage must not continue to be stacked high, nor should it simply be dumped in a corner of the warehouse taking up space. Handling depends on the situation: repair what can be repaired, dismantle and recycle what cannot—do not let a damaged cage become a safety hazard.
Which damage can be repaired? Cracked welds, locally broken mesh wires, damaged hinge latches—these are low-cost repairs; re-welding or replacing parts restores serviceability. After repair, run a simple test: load 80% of the rated load and observe for half an hour to see whether the repaired area deforms or makes abnormal noise. Repaired cages should not continue at the original stacking height; dropping one layer for use is safer.
Which damage is not worth repairing? Severely bent posts, base frames twisted by more than 10 mm, pipe walls thinned by rust beyond 30% of original thickness—for these cages structural strength has already declined; even if repaired they are not safe, and stacking them is itself a hazard. In such cases do not repair; dismantle and scrap them directly.
How is dismantling and recycling done? Warehouse cages are mainly made of steel wire and steel pipe; after dismantling they are recycled as scrap steel. First remove detachable parts such as hinges, door latches, and casters; keep usable spares, sell unusable ones as scrap iron. Cut up the cage mesh and skeleton with a cutter, priced by scrap-steel weight—generally two or three yuan per kilogram.
How do you build a damage-handling workflow? We recommend setting up a repair-pending zone and a scrap zone in the workshop: damaged cages are first gathered into the repair-pending zone, and the equipment administrator evaluates them once a week—those repairable are scheduled for repair, those beyond repair go through the scrap process. Nanjing Tongnuo Warehouse Equipment Manufacturing Co., Ltd. reminds you: do not run damaged cages "sick"; the repair cost of a single cage is far less than the smallest fraction of a collapse accident.
