The caster-equipped foldable cage is a standardized logistics container common in storage and logistics. Xintongnuo lays out its design and advantages below. Design: Folding structure: achieved through special hinges or connectors; when not in use the cage folds flat, greatly cutting storage space and easing packing and transport. Caster setup: four casters are usually fitted to the bottom, commonly two swivel casters plus two rigid casters with brakes, so the cage turns and moves flexibly and handles easily around workshops and warehouses. Frame: mainly welded from cold-hardened quality steel for high strength and a large load; the bottom is reinforced with welded U-channel steel for stability and load capacity; the four feet are stamped parts. Advantages: Efficient space use: the folding design lets idle cages stack flat and save warehouse space; loaded cages stack four layers high for three-dimensional storage. Easy, flexible handling: casters make the cage easy and light to move, one person can move it alone. Suited to factories that need frequent short-distance turnover around the workshop.
