Which of the following describes roll cages?

Roll cages, also known as roll containers or roll trolleys, are specifically designed as frames with wheels that facilitate the transportation and storage of goods. They often have four wheels, allowing for easy mobility, and are typically made of metal or robust plastic. These structures are commonly used in retail environments, warehouses, and logistics to move large quantities of items efficiently and securely.

Their design provides an open framework that enables easy access to the goods stored within, and they often feature mesh sides to keep products secure while maintaining visibility. This makes them particularly effective for tasks such as restocking shelves, transporting items between departments, or moving goods from a loading dock to storage areas. The emphasis is on their mobility and capacity to hold and transport multiple items at once, distinguishing them from other equipment like machinery, electric trucks, or standard pallets.
