The purchase process of the shelf system
The purchase process of the rack system mainly includes: the demand side proposed the warehouse shelf system request--the supplier to plan the design selection--The plan discussion and the optimization--the plan rationality, evaluation of optimization--quotation--Supplier selection--contract signing--racking system detailed technical design--Racking system manufacturing (preparation, processing, surface treatment, packaging, etc.)--rack system installation--acceptance.
Requirements for warehouse shelf systems usually include: Warehouse plan, Unit (packing) of the goods specifications, characteristics, weight, Unit pallet cargo specifications, heap height and load, storage mode and access equipment, access requirements, access frequency requirements, management system requirements, control methods.
II. Classification of racking systems
1. By shelf is fixed or movable type, can be divided into
⑴ fixed-type shelves: fixed-type shelves can be subdivided into shelf shelves, pallet-type shelves, through-type shelves, gravity-type shelves, pressure-type shelves, loft-style shelves, steel structure platforms, cantilever shelves, mobile shelves, drawer-type shelves, etc.
⑵ Mobile Shelves: Mobile shelves can be subdivided into mobile shelves and rotary shelves, in which mobile shelves can be subdivided into light medium-type shelves, heavy-duty pallet-type mobile shelves, rotating shelves can be subdivided into horizontal rotation, heavy vertical rotary racking two kinds.
2. According to the overall structure of the shelf is welded or assembled, can be divided into
⑴ Welded Shelves
⑵ Assembled Racking
At present, most of the domestic use of assembly-type shelves.
3. The connection between the shelf system and the warehouse structure can be divided into
⑴ rack-and-type shelves
The shelf system and the building roof form an integral whole, the roof load is directly supported by the shelf column, and the building enclosure (wall) structure is installed on the two sides of the column.
⑵ separate structural Racking
Shelf systems and buildings are two separate systems, with no direct connection to one another.
4. The load per layer of the unit shelves can be divided into
⑴ Light Racking: Each layer load weight is not greater than 200KG.
⑵ medium Shelf: Each layer contains a weight of 200~500kg.
⑶ Heavy Duty Racking: Each layer carrying weight is above 500KG.
5. The height of the shelves is divided into
⑴ low shelf: height below 5M.
⑵ High shelf: high 5m~12m.
⑶ Super high shelf: 12M above.
III. Structure characteristics, application range and selection principle of various racking systems
1 Shelf Shelves
Shelf shelves are usually manual access goods, assembled structure, evenly adjustable layer spacing, goods are often used for parts or not very important packaged items (convenient for manual access), the height of the shelves is usually 2. Below 5M, otherwise the manual is difficult to reach (such as the auxiliary with the ascent of the car can be set at around 3M). Unit shelf span (that is, length) should not be too long, the depth of the unit shelf (both width) should not be too deep, according to its unit shelf weight of each layer can be divided into light, medium and heavy shelf shelves, laminates mainly steel plate, plank two.
⑴ Light Shelf Shelf: unit shelf weight is not greater than 200KG per layer, the total load is generally not less than 2000KG. The unit shelf span is usually not less than 2M, the depth is not less than 1M (more than 0.6M), the height is generally within the 3M, the common angle-type column shelf structure, the appearance is lightweight, beautiful, mainly applies to store light, small items. Capital investment is less, widely used in electronics, light industry, culture and education industries.
⑵ Medium Shelf Shelves: unit shelves for each layer of load generally between 200~800kg, the total load is not generally less than 5000KG. The unit shelf span is usually not greater than 2.6M, the depth is not less than 1M, the height is generally within 3M. If the unit shelves span more than 2M, then the general can only be selected with beam type medium shelf shelves. Non-beam medium-sized shelves with a beam-type medium-sized shelves compared to the layer spacing can be more room to adjust, more solid, beautiful. Better coordination with the environment, more suitable for some cleanliness requirements of the warehouse; a beam-type medium shelf shelves are highly industrialized and are more suitable for storing metal structural products. Medium shelf Shelves are widely used in all walks of life.
The selection process of the shelf system includes: the demand side puts forward the warehouse shelf system requirements > The supplier makes the scheme Design selection > scheme discussion and optimization > scheme rationality, optimization evaluation > Price > supplier selection > Contract signing > Racking system detailed technical design > racking system manufacturing (preparation, processing, surface treatment, packaging, etc.) > Racking system Installation > acceptance.
