drum racks evolved from pallet racks, using roller rails or bottom wheel pallets. drum rack is one of the derivatives of beam rack. the structure of the rack is similar to the beam rack, except that the drum track is installed on the beam, and the track is inclined at 3-5°. gravity shelves use one sideway as storage and one sideway as takeout. the roller line is tilted and fixed on the shelf beam at a certain angle. the pallet is placed from the high end and slides down along the roller line by its own gravity. to control the pallet to slide at a stable speed to avoid impact. , set a damping system at a certain distance on the drum line, the faster the tray slides down, the greater the resistance generated by the damping system. the end separation mechanism is set at the lower end to separate the two trays at the lowest end so that the lowest end tray can be taken out smoothly. the pallet goods are transported to the shelf inlet by forklift, and using their own weight, the pallet automatically slides from the entrance to the pickup port at the other end, truly realizing the principle of "first in first out". shelf depth and number of layers can be determined according to customer needs. gravity shelves are suitable for the storage of similar goods in small quantities and large quantities, and the space utilization rate is extremely high. the characteristics of the system are: ◆suitable for warehouses with relatively high cost per unit area of warehouses, such as cold warehouses, warehouses with high rents, etc. ◆the first-in first-out storage principle is achieved, which is suitable for storage with strict requirements on the storage date, such as the food industry and the pharmaceutical industry. ◆can provide about 20% picking ◆safety and operating efficiency are higher than drive-in shelves. ◆compared with beam-type shelves, it can improve the utilization rate of the ground by about 70% ◆it only needs to be equipped with a forward-moving forklift or a counterweight forklift, and the operation requirements of the forklift are lower than those of the drive-in type.
