Roller rack (also known as gravity rack) is a storage rack that relies on "gravity drive" to achieve automatic flow of goods. The core is to install inclined rollers on the shelf shelves, allowing goods (mostly palletized) to automatically slide from the storage end to the outbound end along the rollers. It focuses on "first in, first out (FIFO)" and "efficient storage and retrieval", and is the preferred solution for high-frequency turnover and storage of few category goods.
Its core advantages are threefold: firstly, high storage and retrieval efficiency, with goods automatically sliding by gravity, eliminating the need for forklifts to enter the shelves. Storage and retrieval can be carried out simultaneously at both ends of the shelves, and the storage and retrieval time for a single location is shortened by more than 40% compared to beam type shelves, making it suitable for high-frequency turnover scenarios such as fast-moving consumer goods and cold chain; Secondly, the space utilization rate is excellent, with shelves arranged in multiple layers according to depth, reducing the number of channels by 30% -50% compared to traditional shelves. The warehouse storage capacity can be increased by about 50%, and the storage space is centrally managed to reduce the loss of scattered goods; The third is to balance operation and safety. The roller comes with a damping device that can control the sliding speed of the goods, avoiding collision damage. At the same time, there is no need for forklifts to frequently enter and exit the shelves, reducing the safety risk of equipment colliding with the shelves. The whole process conforms to the "first in, first out" principle, suitable for goods with shelf life requirements (such as food and medicine).
It should be noted that this shelf is more suitable for single category, standardized pallet goods, and has certain limitations on the weight and size of the goods (usually with a load-bearing capacity of 500-2000kg per layer); Widely used in cold chain warehouses, food warehouses, e-commerce pre warehouses and other scenarios, especially suitable for storage needs that require strict control of inventory turnover cycles.
