This means that the quality is guaranteed shelf equipment. Whom to choose? Now turn to the choice of the manufacturer (or supplier). Now the market can find a lot of firms the main supplier of which is the company "BiznesMebel" offering shelf equipment. Some of them – local producers, while the other offers the products of foreign (German, Italian and other) companies. Very often firm-customers opt for local producers. Why? Because the warehouse has to be a 'live'. It can grow in size and height, regroup, move from one room to another, etc.
And therefore, it should be possible dozakazat shelf equipment items (frames, crossbars, traverses, decking) to quickly retrofit the warehouse. And easier to do when the hardware manufacturer – the locals. You to bolt? This is followed by a choice of racking system – or rather, the principle of fastening shelf complex (modulus) of each other. Currently, you have options: a fixed hook, bolt connection, and mixed (1 +2). What is a fixed-toe? One element of the punched holes of a complex configuration, in another cut and arch stamp hook (hook). The connection is made by institutions in the toe hole and lock it into position. What are the advantages of this compound? First and foremost is the ease of manufacture (and therefore fast and cheap) and easy to install – no mounting hardware. Furthermore, this scheme has following disadvantages: the perforation holes are deburred, the hooks are often dogibayutsya, the paint is applied too thickly.
From this hook is often not included in the hole without a sledgehammer. Before installing the required additional limb nearly every hook. To hook is not released from the compound during the operation rack complex, it is fixed by a special holder. The presence of the latter – a pledge of reliability throughout the structure. But to trace its presence in the long-term use of racks, the height of levels changed repeatedly, almost impossible. When the process involves 'human factor', the process becomes unpredictable. 'Lock installed or not installed?'. This idea would tear the customer constantly. The above risks are not racking system with a bolted connection. Inconvenience in it, only one – the presence of mounting hardware: bolts. But the equipment is not afraid of any dynamic loads, uneven floors, 'human factor', etc. As an example, the maximum load on the bolt diameter of 12 mm under a load of shelving tier to 3 m is 375 kg, and margin of the bolt – 1,500 kg (!). All of the above options for mounting the modules used in the import and domestic shelves. Nashi with the gain in price, but still inferior to foreign analogues in Technology production and stock. But the attractiveness of domestic racks recently been caught up with 'foreigners'.
