The gravity shelf adopts the advanced and backward storage method. The storage shelf depth 1 and the number of superimposed layers can be determined on demand. The gravity cargo structure is similar to the pallet rack. It is only equipped with drum track on the load-bearing beam. The track is 3-5 degree skewed. It is suitable for storage of a small number of similar goods and has a very high indoor space utilization rate.
Its basic principle is to use the weight of the cargo body to make the cargo body exercise from high altitude to bottom on the safe passage with the necessary height-width ratio difference, and then carry out the work of taking, storing and entering the warehouse。
