Gravity shelves are a type of shelf with a relatively complex structure and are relatively expensive. According to the summary of Kored Shelves, gravity shelves are also called self-gravity shelves, pallet-type storage shelves. Their structures are similar to beam shelves. They adopt a roller seat design and are appropriately tilted. The self-weight of goods is used to drive the flow. Pallets are densely stored and have better physical circulation. , to achieve the first-in-first-out logistics effect. There are dampers, rollers, etc. on the gravity rack track, and the price is relatively high. The price of the entire system includes the shelves, dampers, rollers, etc., so the price is naturally relatively high, and one cargo space may cost 800 yuan.
Advantages of gravity shelf combination:
There is no working channel between groups of gravity shelves, thus increasing the space utilization rate by 60% and improving the storage volume ratio. Pallet operation follows the first-in-first-out principle, with automatic storage and rotation. The separation of storage and picking greatly increases the output. Since the goods slide due to gravity and there are no operating channels, the number of transportation routes and forklifts is reduced.
Notes on the design of gravity shelves:
The total depth of gravity shelves (i.e. the length of the guide rails) should not be too large, otherwise the unavailable upper and lower "dead corners" will be large, affecting space utilization. , and if the ramp is too long, the controllability of the descent will be poor, and the momentum of the descent will be greater, which may easily cause the descent to be blocked, blocked, and the pallet cargo to tip over.
