Gravity shelving is a type of storage rack that utilizes the gravity of goods to achieve automatic transportation. Its characteristics are as follows: Automated storage: The shelves are equipped with roller or slide tracks, and the goods slide automatically from the high end to the low end by gravity, without the need for manual handling, achieving "first in, first out" (FIFO), suitable for goods with shelf life requirements. High space utilization: Adopting a dense storage design with fewer channels, it can fully utilize the vertical and horizontal space of the warehouse, and the storage density is 30% -50% higher than ordinary shelves. Efficiency improvement: Goods storage and retrieval do not require forklifts to enter the interior of the shelves, reducing forklift operation paths, improving loading and unloading efficiency, and reducing the risk of forklift collisions with shelves. Structural stability: The main body of the shelf is made of welded or assembled steel, with strong load-bearing capacity, suitable for storing regular goods such as boxes and pallets. High cost: The initial equipment and installation costs are high, and there is a high requirement for consistency in the specifications of the goods. Irregular goods are prone to jamming and affect transportation.
