Therefore, the storage shelves on the development of modern industry play a huge role, with the development of modern industrial civilization, storage shelves structure and function are constantly improving.
Storage shelves according to its load-bearing capacity, process modeling, use, etc. have different classification.
According to load capacity
Heavy duty pallet rack
Heavy-duty pallet rack with high-quality cold-rolled steel plate by the roll forming, the column can be up to 10 meters and the middle of the seams, beams selected high-quality square steel, bearing capacity, not easy to deformation, between the beams and columns for the cylindrical bulge inserted, Reliable, easy disassembly and use, and the use of locking nails to prevent forklift work when the beam to stir; all the surface of the shelves were pickled, phosphating electrostatic spraying process, anti-corrosion rust, beautiful appearance. Applicable to large warehouses.
Medium-sized shelf modeling chic, reasonable structure, easy assembly and disassembly, no screws, and strong and strong, bearing capacity, widely used in shopping malls, supermarkets, enterprises
Medium storage shelves
Medium storage shelves
Industry warehouses and institutions.
Light-duty perforated shelves are a highly versatile structural system that can be used in assembling lightweight racks, workbenches, tool carts, suspension systems, safety nets and support girders. The length of the punching angle can be cut quickly according to the scale, assembled with screws, modified and re-installed, so that it can meet the use of careful planning, but also to meet the needs of emergency use.
According to process modeling
Mold rack, also known as drawer-style shelves, also known as mold shelves, mainly to store a variety of mold items, according to the requirements of the layer capacity is divided into light mold shelves and heavy mold shelves. The top of the shelf can be configured to move the hoist car to facilitate the lifting of the mold.
Beam-type shelves safe and convenient, suitable for a variety of warehouses, direct access to goods. Is the easiest and most widely used shelf. Can make full use of space. Using a convenient tray access, effective with the forklift loading and unloading, greatly improve operational efficiency. Mechanical equipment requirements: anti-balanced forklift or stacking machine. Stacking machine can improve the ground space utilization rate of 30%, operating height of 16 meters; beam shelf features: smooth inventory turnover. Can provide 100% picking ability. Increase the average picking rate. Provide high-quality product protection. Because the beam-type shelves for more varieties, bulk cargo storage, in order to facilitate access, the design of the roadway will be more, so the ground utilization rate is relatively low.
Corridor-style shelves have also become through-type shelves, into the shelves. Designed to store a large number of similar pallet goods. Tray one by one in the depth of the direction of storage on the support rail, increasing the storage density, improve the space utilization. This kind of shelf is usually used in storage space is expensive occasions, such as frozen warehouses and so on. Corridor shelves have four basic components: frame, rail support, tray rails and bevel rods. This shelf storage utilization is high, can be achieved first-in first-out, or advanced out. Suitable for storage of large quantities, less variety of goods, bulk operations. The maximum amount of space available can be provided. It is suitable for large quantities, less variety of goods storage operations. Forklift can be directly into the cargo channel to access the goods, the operation is extremely convenient. Mechanical equipment requirements: anti-balanced forklift or stacking machine shelf features. Applicable to storage of low storage capacity; can provide 20% -30% of the optional; for the low rate of the warehouse. Ground utilization: 60%, higher (calculated according to the above design)
Grain-type shelves do not need to operate the channel relative to the ordinary pallet rack, so increase the space utilization of 60%; tray operation to follow the principle of first-in first-out; automatic storage of rotation; storage and sorting the separation of the two operations greatly improve the output, Is the gravity of the goods to slide, and there is no operating channel, so reduce the number of transport routes and forklifts. In the channel on each side of the shelf, are installed with a certain slope, with orbital rails, storage unit cargo under the action of gravity, from the storage side of the flow to the library side. Such a warehouse, there is no work between the row and the channel, greatly improving the utilization of the warehouse area. But the use of the best in the same row, the same layer of goods, should be the same goods or a storage and delivery of goods at the same time. High-level adjustable, with a variety of models forklift or stacking machine, to achieve a variety of tray access, unit cargo maximum load of up to 5000kg, is the most commonly used storage of all walks of life.
Cantilever shelves are suitable for storing long cargo and irregular goods. The extended cantilever has a lightweight structure and good load capacity, and can greatly improve the utilization and working of the warehouse when storing irregular or length-specific materials effectiveness. Increased shelf, especially for small space, low degree of the Treasury, easy management, wide field of vision, compared with the ordinary shelf shelves, the utilization rate is higher.
Loft-style shelves all modular structure, can be used wood, pattern plate, steel, and other materials to do floor, flexible design into a two-story and multi-layer, for hardware tools. Electronic equipment, mechanical parts and other items of small packaging parts storage, storage of multi-species, low-volume cargo full use of space. Applicable to the limited variety of venues, the number of cases, it can increase in the existing site several times the utilization rate, can be used with the lift operation. Full modular structure, dedicated light steel floor, low cost, fast construction. Can be based on the actual site and needs, flexible design into a two-story, multi-layer, make full use of space.
Among them, the special shelves include mold racks, oil drums, fluent shelves, grid, climbing cars, net compartments, six categories, the rest is the more common shelves.
Fluent-style shelves: the use of fluent, the goods into the plastic box or turnover box, the use of cargo weight, to achieve the first-in first-out goods for the production line or assembly line material storage, material box can rely on gravity along the wheel down.
Trailer rack features: forklifts do not need to enter the roadway, saving time, improve the safety of personnel and cargo, the Treasury cargo access efficiency greatly improved, make full use of the Treasury space, the Treasury can use about 80% to 85 space; Different types of products can be layered flexible access; compared to the entry into the frame, through the frame, the structure of a solid, high safety factor can be achieved first-in first out and advanced; can be automatically collated, inventory.
1, storage shelves; 2, supermarket shelves; 3, books shelves; 4, audio and video shelves; 5, vegetable shelves; 6, grain and oil shelves.
A brief summary of the selection of storage shelves, should pay attention to several points
(1) plant structure (available height | beam and column position | floor conditions | fire protection facilities)
Storage equipment selection rack should be considered under the effective height of the beam to determine the shelf height. While the beam position will affect the shelf configuration. Floor to withstand the strength of the ground flatness and the design and installation of the shelves. In addition, it is necessary to consider the installation location of fire protection facilities and lighting facilities.
The shape and size of the stored items are directly related to the selection of the shelf specifications, and the weight of the stored items directly affects the shelf of the strength. The units of storage, in what units to store, tray (pallet) or storage cage or a single product has a different type of shelf selection. Also estimate the total number of reserves, must take into account the company's growth needs in the next two years. This information can be obtained through the storage system analysis, but also ask us to Teng shelf in the design before giving some professional advice.
(3) Accessibility (storage density | first in first out | storage management)
General access and storage density are relative. That is, in order to obtain a higher storage density, the access to the item must be relative to the sacrifice. Although some types of shelves can get better storage density, but relative to its storage management is more complex, and often can not be done first-in first-out control. The best of course the three-dimensional automatic warehouse can be developed, access and storage density is superb, but the relative cost of investment is more expensive. So what type of storage equipment, can be said to be a compromise of various factors, but also a strategy of application. For each type of storage device access and storage density comparison, you can inquire.
(4) Handling equipment (counterweight | cross-vertical | channel width | lifting height | lifting weight | rotating radius)
The access operation of the storage device is performed by the handling equipment. Therefore, the choice of storage equipment to be considered with the handling equipment. Stacker is a general general handling equipment, and the shelf channel width, will directly affect the pile selection of the machine type, is the weight or narrow channel.
(5) out of the library (first in first out | access frequency | access number)
Some types of shelves have a good storage density, but the amount of incoming and out of the library is not high, suitable for low-frequency operations. Out of the library is a very important amount of data, which is the choice of shelf selection considerations.
Storage rack bearing capacity, storage shelves each layer carrying up to 5000kg, access to fast and convenient, is the most widely used pallet cargo storage system, a strong versatility. The structure is the shelf along the width of the warehouse into a number of rows, leaving a roadway for stacking cranes, forklifts or other transport machinery. Each row of shelves is divided into columns along the longitudinal direction of the warehouse, divided into layers in the vertical direction, resulting in a large number of cargo spaces for the pallet to store the goods.
Features: Each tray can be stored or moved independently, the warehouse shelves make the cargo loading and unloading process easier and faster. Can be adapted to various types of goods, according to the size of the requirements of the adjustment of beam height, as much as possible to use the upper space of the warehouse. Supporting facilities the most simple, lowest cost, installation and removal is extremely convenient.
Storage shelves are made of high quality steel, the surface of the electrostatic spray treatment, corrosion / rust / strong and beautiful. Its various specifications and load-bearing design to meet the factories, warehouses, assembly lines, storage supermarkets use requirements. When you need the shelf 100-150kg per load, this shelf is the ideal choice, but also the composition of the platform, so light shelves suitable for factory storage of light spare parts and storage supermarket use. Plug-in assembly, easy installation and disassembly, wide range of uses
