Pallet Flow systems are high density pallet storage systems that utilize depth to increase capacity. This system uses a slightly inclined rail with rollers that allow pallets to move easily along the sloped plane. These systems are also called gravity flow or dynamic flow systems. The pallet flow system often has complex motion and braking systems to control the speed of the moving pallet. Pallet Flow racking systems are either a FIFO (first in, first out) or a LIFO (last in, first out) storage system. If the system is loaded from the back and unloaded from the front, its FIFO; if the system is loaded and unloaded from the front its a LIFO system.
Usefulness of topic in DCM
1. First-in, first-out (FIFO) inventory control.
Loads are transported, via the flow rails from the loading end to the unloading end of the storage system. The first load in is always the first load to be taken out. This constant stock rotation is especially beneficial with perishable or time-sensitive goods, such as food or pharmaceuticals, where a lost product becomes a lost profit.
2. Reduced handling costs.
Once loaded, product rotation is automatic. The SK3400 rack eliminates labor and fork truck operation to rearrange loads. And Steel King flow rails are powered by gravity, requiring no electricity or other utilities.
3.Reduced handling equipment costs.
Fork lifts are required only for the initial loading and final unloading. Because only two aisles are necessary, aisle space can be reduced by 75 percent. Fewer fork lifts, operating fewer hours, and consuming less fuel can accomplish the same handling function.
4.Time and labor savings.
With only two aisles, each dedicated to specific functions (loading or unloading), traffic is more orderly, employees are more efficient and overall productivity is improved.
5. Space savings.
Because storage density can be doubled, storage capacity can be increased within the same storage area, or a portion of your existing storage area can be made available for other uses.
6. Construction cost savings.
By increasing storage capacity within existing facilities, the need for new construction could be eliminated. When new construction is necessary, building size and cost can be reduced by up to 50 percent. A smaller warehousing area, in turn, can reduce insurance, land acquisition costs, and taxes.
7. Operating expense reduction.
Higher density storage and consequently smaller storage areas also mean less area to heat, illuminate, air condition, and/or refrigerate.
8. Decreased fork lift damage.
Decreased fork lift handling of loads can result in less product damage and less potential for collision damage to the rack structure.
9. Flexibility.
Flow storage systems have been successfully installed as a part of virtually every storage function, including raw materials receiving and storage, work-in-process, buffer storage, finished goods, order picking, and cross docking.
