[0002] Freight elevators, also known as cargo elevators or freight transport elevators, are vertical transportation equipment specifically designed for transporting goods. They are widely used in factories, warehouses, shopping malls, logistics centers, and other locations, effectively improving cargo handling efficiency and reducing labor costs. Freight elevators typically have a large load capacity and a robust structure to ensure safety and stability when transporting heavy goods. Because trolleys are frequently used to move large items inside freight elevators, it is essential to protect the inner walls from impacts. A common practice is to line the inner walls with foam or similar materials; however, over time, this foam can damage and fall off, losing its protective effect.
