For the placement of goods in warehouses, many different designs are used. One of them is front pallet racks. Their design is presented as a system for storing goods on conventional pallets. Since the products are easily transformed, they can be used to store large and small items without pallets. Designs are indispensable in warehouses.
Many goods require special storage places so that they do not deteriorate from various influences. For this purpose pallet racks serve. They are placed in warehouses in accordance with the convenience and safety, so that unloading is carried out quickly.
The concept
For the convenience of transportation and movement, weights are stored and secured with straps on wooden pallets. Then they are placed for storage in a warehouse. Racks are multi-level structures that are assembled from component parts of frames and beams.
The racks can reach 12 meters in height. The length is determined by the number of sections. They are distributed in 1 or more lines. You can also collect straight and angular structures. The bearing surface includes 2 or more beams. They put pallets with cargo. Boxes, boxes and barrels are also placed on pallets. Manufacturers produce various pallet racks.
Equipment
Products have a very simple design: they consist of frames and beams. They are made quickly enough and spend a little time on installation. The racks have vertical frames and horizontal beams of different lengths. The package includes locks that protect the structure from falling. Racks have a high bearing capacity.
Domestic products are no worse in quality than European ones. Galvanized steel is not a sign of unreliable products. S350 steel is used for high-quality shelving, the beams are made of St3ps steel.
Scope of use
Front pallet racks are applied:
- in small warehouses and large enterprises;
- at wholesale bases;
- in the trading floors of shops;
- in production shops;
- in warehouses for storing chilled or frozen products.
Thanks to such indoor products, an order is maintained that meets safety requirements.
Features
Front-mounted collapsible products from separate parts are installed. There will be one line or two - it depends on the type and area of production. The number of tiers and cells is set as necessary.
The system consists of:
- Ram including galvanized racks. Parts are fastened with riveting and bolt elements.
- Beams made of metal profile with hooks. Fastening is provided with the help of special clamps.
Using different sizes of vertical frames, it will be possible to adjust the shelving based on the desired depth and height. The length of the section and load is determined by the length of the frame. To ensure that the load on the front pallet racks is appropriate, special tables are used in the calculations.
Types of shelving
Products are island, which provide a load on 2 sides. There are also wall shelving. All designs are divided into 4 types:
- Narrow aisles, since between them is 1.5–2 meters. This saves storage space. The product is used when it is possible to install high racks, with a rich turnover of goods. The disadvantages include the need to use expensive equipment for storage. And all this increases the cargo turnover.
- Broad-wire. The distance between them is within 2.5-3.5 meters. The product is considered more affordable and easy to install. Each product is provided with free access. These front pallet racks are not economical in space consumption, as they occupy about 40% of the room.
- Double depth. The product is obtained using shifted designs. This is necessary to increase the usable area, due to the increase in the density of the arrangement. But in this case a stacker or forklift is required. Such racks are used when the wide-aisle option does not allow providing the warehouse with the required usable area.
- Mobile racks mounted on special mobile devices. Their movement occurs on rails using an electric drive. For mobile structures, additional costs are required for electricity and the installation of a security system.
Benefits
Front loading pallet racks have the following advantages:
- A wide range of designs that differ in load, quantity and parameters of the placed products.
- There is free access to goods; no movement of pallets is required to get the necessary pallet.
- The use of pallets of different types.
- Can be used to store small items.
- Accounting is provided by marking storage locations.
- Products are placed in different rooms.
- You can fill structures completely.
Front pallet rack for warehouses is one of the most sought after and practical. It is perfect for long-term storage of goods.
But the designs also have disadvantages:
- It is necessary to equip a wide passage between the racks, because of which the usable area is reduced by 30-40%.
- Additional costs for electricity, because the structures operate on an electric drive (mobile shelving).
Specifications
Distinctive features are front pallet racks. Their technical characteristics are as follows:
- Material - rolled steel.
- Rack width - 70, 90, 110, 130 mm.
- Frame coating - galvanized, polymer.
- Rack pitch - 50 mm.
- The depth of the frame is 800, 1000, 1100 mm.
- Height - 2.2-14 m.
- Types of fastening - hook-on, metalless.
- The load is 4000–25000 kg.
- The length of the racks beams is 1000–3600 mm.
Part Dimensions
Manufacturers create different front pallet racks. Part sizes may vary. Products are selected based on the area of the room, the weight of the goods, types of equipment. Frames are available in sizes of 70, 90, 110, 130 mm. Each design has its own load limit. The capacity depends on the number of tiers.
An important part of the product are beams. They come in 6 species, characterized by the height of the cross section of the profile. The longer the section length, the lower the load capacity. Each front room has its own front pallet racks. The photos presented in the article show how these designs look.
Rack selection
Acquire designs suitable for specific parameters, based on the following recommendations:
- First, you should decide on the load, which will determine the weight of the products and goods. Using this parameter, you can determine the dimensions of the racks and beams.
- It is necessary to take into account the structural details of the traverse - they must have a load exposure. The weight of the goods should be equal not only to the strength of the beams, pallets, shelves, frames should be resistant. The type of rack depends on the cell capacity: frame, pallet or shelf.
- It is necessary to determine the cell parameters, which should be suitable for the size of the stored cargo. Pipes require cantilever products, and boxes require shelving with square cells.
In the end, you need to double-check all the selection parameters, increasing the design load by 25%. The margin of safety is necessary to increase the service life, with maximum loads the rack will last about 6 months.
