introduce
drive-in shelves are also called corridor shelves or through shelves. the shelf adopts the pallet access mode, which is suitable for the storage of goods with a small variety and large batches. since the system consists of continuous shelves with no aisles in the middle, the storage of goods is handled by forklifts entering the shelves. according to the arrangement of shelves, it can be divided into single-sided driving type and double-sided driving type. the forklift is stored from the innermost position of the shelf to the outermost position. the configuration can be two sets of drive-in shelves arranged back-to-back or a single set against the wall. forklifts use the same roadway for entry and exit. the storage density is very good, but the access performance is limited, and first-in first-out management cannot be achieved. because the forklift is in the entire shelf, the driver must be very careful. the depth of the drive-in shelves is 3-5 rows, and the pile height is four layers. it is the easiest to manage and suitable for products with fewer samples and more volumes. in order to increase the operating speed of the forklift, the guide rail can be selected according to the actual needs. compared with the cargo rack, the storage space utilization rate of the through-type rack (drive-in rack) can be increased by more than 30%. the through-type rack (drive-in rack) shelf) is widely used in cold storage and food and tobacco industries. drive-in shelves are mainly composed of pillars, partitions (beams), corbels (hanging corners), joints, top connections, top forks, back forks and other parts. adopt pallet storage operation, which needs to be equipped with forklift trucks, and the goods are kept in storage for convenience and speed
1. on the support rails, the trays are stored in the depth direction, one after the other, which makes high-density storage possible.
2. cargo storage comes in and out from the same side of the shelf. store first and then take, then store and take first. balance weight and forward-moving forklift can easily drive into the middle of the shelf to access the goods without occupying multiple channels.
3. this kind of shelf is suitable for storing large-volume, low-variety through-type shelves (driving-in shelves). both the corbels and corbel shelves adopt the overall stamping/rolling technology, which has strong bearing capacity and beautiful appearance.
4. the drive-in shelf is fully inserted and assembled. the column is an assembled structure. the total depth of the shelf near the wall is generally best controlled within 5 pallets. the total depth of the shelf that can enter and exit the middle area is generally the best. control within the depth of 10 pallets to improve the efficiency and reliability of forklift access.
disadvantages: the stability of the through-type rack system is relatively weak among all types of racks. for this reason, the rack should not be too high, generally within 12m. in addition, a tensioning device needs to be added to the system. this type of system has dense shelf arrangement and extremely high space utilization. it is suitable for storing a small variety of large quantities of the same type of goods. the goods can be deposited from the same side and taken out from one side and the other side.
penetrating shelf characteristics
suitable for various warehouses, generally stored in pallet units, the simplest and most widely used shelf form. the forklift can drive directly into the goods lane to access materials. high storage density and large storage capacity. the shelf is suitable for the storage of large quantities, few varieties, and large flow materials. the height of the laminate is adjustable, and the shelf structure is easy to disassemble.
forklifts can be driven into the aisle to store pallets, and the cargo storage channel is also a forklift storage and transportation channel, which is a form of shelf with higher storage density. calculated by the conventional height of ordinary forklifts and the conventional scheme of three layers of goods in the corridor shelves, the effective storage capacity of the warehouse can be increased by more than 100%. in contrast, the investment cost is controlled and the benefits are significantly improved. calculated from the global storage cost, it is generally possible to offset the investment cost by increasing the storage capacity benefit within three years. the access mode is first-in, first-out or first-in first-out: in and out from the same side is advanced and out, and from one side into the other side-out is first-in-first-out.
