A warehouse cage stores goods at fixed capacity, stacks neatly, shows contents at a glance, and makes stock counting easy, while raising storage-space utilization. It is sturdy, ships conveniently and is reusable, cutting labor and packaging costs for warehousing companies. It works on the factory floor, as display and storage in a supermarket, and outdoors. The improved version goes on racking, runs along production lines, and stacks; wheeled units move around the workshop, and PVC- or steel-lined units stop small parts from falling out. Three types are common: the wheeled cage for turnover; the leg-based cage that stacks and goes on rack; and the wheeled-plus-legged cage that covers both.
