How effective are gravity-type roller rack systems in cold storage facilities?

Gravity-type roller rack storage is based on the principle of "first in, first out", and forklifts do not need to enter the storage aisles to retrieve goods. They only need to access the racks at both ends. It is an efficient and high-density storage system. So, how does the gravity-type roller rack perform in cold storage applications? Let's find out.

Firstly, its greatest advantage lies in significantly enhancing space utilization and operational efficiency. Cold storage operations are costly, and every inch of space is extremely precious. The gravity-type rack adopts a dense layout, reducing the number of internal aisles and having a storage density far higher than traditional beam-type racks. Its "first in, first out" (FIFO) logistics principle is automatically realized through the inclined sliding of the rollers. Goods are stored at the top and automatically slide to the lower picking area under the force of gravity. This not only significantly reduces the driving distance and time of forklifts in extremely low-temperature environments, lowers energy consumption, but also greatly speeds up the goods turnover rate, especially suitable for perishable, batch-categorized frozen foods, medicines, etc.

Secondly, it significantly improves the working environment and safety within the warehouse. The internal temperature of a cold storage (usually -18°C to -25°C) poses a severe challenge to workers, and shortening their continuous working time is crucial. Moreover, the gravity-type roller rack can be designed to reach heights of over 8 meters, fully utilizing the space of the cold storage. It has semi-automatic functions but has a much lower cost than automated storage racks.
