Guidelines for 2016 to buy pallet rack systems
Racking is stationary or moving, and can be divided into: (1) fixed-type pallet rack: fixed type racking can be broken down to put plate, pallet, drive-in, gravity type, loaded, loft-style, steel platform, cantilever, mobile, drawer and ox's leg type heavy duty shelves and so on. (2) mobile type heavy shelf: Mobile type heavy shelf can subdivision for mobile type heavy shelf and rotating type heavy shelf, which mobile type heavy shelf and can subdivision for light medium mobile type heavy shelf (and said intensive frame, is divided into manual and electric), and heavy tray type mobile heavy shelf, rotating type heavy shelf and can subdivision for level rotating type, and heavy straight rotating type heavy shelf two species. According to pallet rack structures are welded or assembled, can be divided into: (1) welded heavy-duty shelves. (2) the Assembly type pallet rack. At present, mostly use the assembled pallet rack. Racking system and warehouse structures or not, can be divided into: (1) library-one heavy shelves. Racking systems and building rooftops constitutes an indivisible whole, directly from the pallet rack column supporting the roof load, installed on pillars on either side of the building envelope (wall) structure. (2) the separation of structural pallet rack. Racking systems and buildings as two separate systems, no direct connection between each other. By racking loads on each floor, and can be broadly classified into: (1) light-duty heavy shelf: each floor load capacity is not more than 200kg. (2) medium-heavy shelf: each floor load capacity for 200~500kg. (3) heavy duty heavy shelf: 500kg each floor load capacity. By racking height is divided into: (1) the lower pallet rack: height 5M below. (2) high racking: highly 5~12m. (3) ultra high racking: 12m.
"Structural features of various racking systems, application and selection principle" To put plate racking. To put plate heavy duty shelves are usually artificial access mode, assembly-type structure, uniform spacing can be adjusted, the goods are often not very heavy parts or packaged items (for manual access), racking height is usually 2.5M or artificial reach (such as auxiliary to climb can be set in 3M). Heavy-duty shelves span (length) should not be too long, heavy shelf depth (width) should not be too deep, by its unit racking the loading capacity of each layer can be divided into light, medium and heavy to put plate racking, laminates are mainly for steel plates, wood laminate two kinds. (1) light to put plate heavy duty rack: pallet rack load per floor is less than 200kg, total load is not more than 2000kg. Heavy shelf span is usually less than 2m, depth is not more than 1M (0.6m), high 3M, common steel column pallet rack structures, appearance of lightweight, attractive, mainly suitable for storing light and small items. Less money, are widely used in industries such as electronics, light industry, culture and education. (2) medium to put plate heavy rack: pallet rack load on each floor between 200~800 kg, total load is not more than 5000kg. Heavy shelf span is usually not greater than 2.6m, depth is not greater than 1M, generally in less than 3M. If a range of heavy-duty shelves span 2m, layer is contained in 500kg, the selected non-beam type medium-sizedly plate racking usually more appropriate; if a range of heavy-duty shelves span 2m, you generally only have medium-sizedly beam plate racking. Non-beam type medium-heavy duty shelves Shelves and beam type medium-heavy than spacing can be adjusted a lot more, strong, beautiful, better coordination with the environment more suitable warehouse with high cleanliness requirements; plate racking beam type medium-sizedly industrialized features stronger, more suitable for storage of metal structure products. Medium-sizedly plate racking application widely, applies to all walks of life. (3) heavy duty to put plate heavy duty shelf: heavy duty shelves between each load is usually 500~1500kg, heavy-duty shelves span 3M, depth 1.2m, height is not limited and is usually combined with heavy duty pallet racking, which coexist, several terraces to put plate, manual access operation, height in the 2m part is usually the pallet racking, used forklift access job. Which needs zhengtuo is mainly used for access and save zero zero takes in a large warehouse-style supermarkets and Logistics Centre was seen. Pallet racking pallet racking, also commonly known as the beam type pallet rack or shelf, pallet rack, usually a heavy duty pallet rack, warehouse pallet rack system is most common in the country. First must for set loaded unit of work, is goods packaging and weight, characteristics for group disc, determine tray of type, and specifications, and size, and ask only the contains weight and heap high (ask only the goods weight General in 2000kg within), then which determine unit heavy shelf of span, and depth, and layer spacing, according to warehouse roof trusses Xia along of effective height and forklift of maximum fork high decided heavy shelf of height. Heavy-duty shelves span 4m, depth 1.5M, low, high warehouse racking height in 12m, super high warehouse racking height is less than 30m (this kind of warehouse is automated warehouse, total high racking consists of several 12m columns). Such warehouses, mostly in the low, high warehouse before moving type storage battery forklift truck, balance storage battery forklift truck, forklift, three to access jobs, heavy shelf can also be used when higher electric stacker, super high access by stacker warehouse operation. This racking system in high space utilization, flexible and convenient access, supplemented by computer management or control, and can basically meet the requirements of a modern logistics system. Widely used in fields such as manufacturing, logistics and distribution center, both applied to producing small quantities of goods, also suitable for large quantities and few varieties goods. This type of pallet rack high warehouse and application of ultra high storage up to (automated warehouse pallet rack mostly with such heavy shelf). Drive-in pallet racking drive-in pallet rack, also known as traverse heavy shelving, drive-in racking. This system heavy shelf layout-intensive space utilization ratio is extremely high, almost twice times the pallet racking, but must be large quantities and few varieties goods, goods have been advanced. Set the first unit of work, determine the specifications, the load of the tray and pile high. Determine unit heavy shelf span, depth, spacing, determined according to the roof trusses along height height of racking. Wall total depth of pallet rack is best controlled at 6 pallets deep within, the middle area can be both in and out of racking area the total depth is best controlled at 12Tray depth in order to improve the efficiency and reliability of forklift access (this type of racking system, forklift "raise high" operations, forklift easy to slosh into the heavy-duty shelves, so consider the stability of adequacy is essential). Stability of this type of storage system is weak, the heavy-duty shelves should not be too high, should normally be controlled within 10m, and in order to strengthen stability of racking systems as a whole, apart from the specifications, the selection was great, and also subject to the securing devices. Ask only the goods should not be too big, too heavy, usually weight control in 1500kg, the pallets span should not be greater than 1.5M. Often before moving type storage battery forklift truck or forklift truck balance storage battery forklift truck. Used for dairy products, beverages, food industry, freezer is more common. 4.Gravity type heavy shelf gravity type heavy shelf by tray type heavy shelf evolution and into, used Roller Type track or end of round type tray, track is must slope (3 ° around), using goods of weight, achieved goods of advanced first out, side into another side out, applies Yu large volume, and similar goods of advanced first out storage job, space utilization is high, especially applies Yu has must warranty period, and should not be long-term backlog of goods. Heavy-duty shelves to total depth (Guide length) should not be too large, do not use the up and down "dead" will be larger, space utilization, and the ramp is too long, and controllability of the decline may be slow, downward momentum is large, easy slide jam, block, tilting of the pallet. Falling to make smooth, such as a long ramp, you should add damping device in the Middle, for the pallet fell to the bottom without tipping due to impact too much, should be at the bottom of the ramp buffer device and fetch goods separate device, so difficult to design, manufacture, installation, and higher costs. This heavy-duty shelves should not be too high, generally within 6m, ask only the weight of the goods is generally within 1000kg, its reliability and maneuverability is reduced. This type of racking system is currently used in China is not very great.
