AI Technical Summary
Pallets often suffer from high replacement costs due to bending, deformation, or severe scratches on their bearing surfaces during use.
An easy-to-maintain pallet was designed, including an outer frame and support legs. The load-bearing section consists of alternating bent plates and square tubes, allowing only the problematic second load-bearing section to be replaced, avoiding the need for complete replacement.
Replacing the load-bearing components partially reduces the cost of using and maintaining the pallet, and improves the maintainability and economy of the structure.
