2022-08-12

First of all, we need to understand the material of storage shelves. Generally, the raw materials used in storage shelves are mostly cold rolled steel. In addition, the structure of the storage shelf is directly affecting the stability and bearing capacity, such as the frame of the storage shelf to see the bending of the section, the more Angle, the better the dispersion force; And the shelf beam according to the load-bearing requirements to choose specifications, but also to see the BEAM hook structure (BEAM on the teeth of 3~4, the force is good), beam hook to the inside of the column side close without gap, so as to ensure the stability of storage shelves, long-term use is not a problem.

Storage shelf manufacturers have learned that the surface spraying of good quality storage shelves is also better, and the phenomenon of paint dropping can not occur, otherwise it is easy to rust over a long time. Usually before spraying, it needs to go through multiple processes, including seven processes, such as oil removal, rust removal, pickling and phosphating. After treatment, the steel surface meets St2 level requirements, coating thickness: 60-80 microns, adhesion ≥2 level, surface hardness 2H, pencil without scratch, salt corrosion resistance of more than 500H, so that the finished product will not drop paint and rust.

Cantilever type shelf is a kind of heavy shelf, cantilever type shelf is suitable for storing long raw materials, ring raw materials, furniture boards, pipe fittings and irregular goods, cantilever can be single or two sides, cantilever type shelf has a stable structure, good load working capacity, high space utilization. The height ratio of cantilever shelf is usually within 2.0 meters (if the goods are stored by electric forklift truck, it can reach 6 meters), the length of the cantilever is within 1.5 meters, and the bearing capacity of each arm is usually within 800KG. Cantilever shelf vertical rod is made of H section steel or cold rolled channel steel, cantilever is made of square steel pipe, cold rolled channel steel or H section steel, between cantilever and vertical rod is made of insert type or screw connection type, between base and vertical rod is made of thread connection type, and cold rolled channel steel or H section steel is made of base. Cantilever shelves are ideal solutions for heavy, scattered or other special goods. Cantilever shelves have two arms and arms for efficient storage of wood, pipe fittings, bars and other similar goods. Cantilever shelf is arranged on the traditional storage shelf support of the outer cantilever, is a kind of long object special storage shelf. Cantilever shelves are used in the field of mechanical equipment manufacturing and building materials mall, etc., plus the shelf, especially suitable for small indoor space, relatively low height of the warehouse, convenient management method, spacious sight line, the use rate is higher than the general storage shelves.

Classification of stereoscopic warehouse shelves

Three-dimensional warehouse shelves refer to the shelves used to place goods in the warehouse, which is widely used in industrial warehouses. Three-dimensional warehouse shelves focus on the upward development, make full use of the storage space of the warehouse, his height can reach more than 40 meters, and ordinary shelves are only 3~5 meters, according to the classification of structure, three-dimensional warehouse shelves can be divided into beam shelves, Corridor shelves, gravity shelves, attic shelves and so on. The next step is to analyze the types of three-dimensional warehouse shelves with you one by one, to help you have a deeper understanding of three-dimensional warehouse shelves. In the three-dimensional warehouse shelves, the beam shelf is more convenient and faster in the storage of goods, which ensures that any kind of goods are first-in, first-out and there is no restriction of the type of forklift truck. It can pick up goods at a faster speed. Its space utilization rate can be as high as 30%~50%, and the specific utilization rate is determined by the type of forklift truck. Which is usually the shelf of its storage density is relatively high, is advanced after the type of part, when the pick up has 20%~30% of the space utilization rate, but in fact, the pick up speed is relatively general, its storage space can reach 60% of the overall warehouse, that is to say, it can make full use of 60% of the space. Gravity shelf, its working efficiency is relatively high, and the density is very high, at present. Secondly, the free access type design is adopted. The circulation rate of inventory is very high, and the goods can be picked up according to the order. The speed of picking up goods is relatively fast. Usually for 2 to 3 layers can be designed to lift goods elevator and stairs and simple attic shelves, in fact, the use of double column as a support part of the risk or card can be applied to some warehouses, relatively high, at the same time the goods are relatively light, the need for artificial storage warehouse, when the inventory is relatively large, you can use the elevator or hydraulic lifting platform. Cantilever shelf is an important kind of shelf in the three-dimensional warehouse. Cantilever shelves are suitable for storing long materials, ring materials, plates, pipes and irregular goods. Cantilever can be single-sided or double-sided, cantilever shelf has stable structure, good load capacity, high space utilization. Cantilever shelf column mostly uses H beam or cold rolled beam, cantilever uses square tube, cold rolled beam or H beam, cantilever and; The column is inserted or bolted, the base is bolted to the column, and the base is made of cold-rolled section steel or H-section steel.

Are you using storage shelves correctly?

Storage shelf is an important storage equipment in modern industry. If there is unreasonable operation in use, it will lead to the stagnation of goods access and affect the progress of work. How to use the shelf to make the most of it? The following is a simple understanding of how to optimize the warehouse shelf? Warehouse shelves should be classified reasonably. Each area should plan what items to put, and then mark the name, model and quantity of goods on the shelves. The third suggestion is to set up the waiting area and the batching area in the warehouse to facilitate the warehousing and discharging of goods.

How to prevent light shelf deformation in use?

In the design of lightweight shelf specifications, should consider the use of requirements, equipment conditions, load weight, material supply and installation conditions and other factors. The dimensional tolerance, deformation and clearance of the light shelf shall meet the relevant standards. Light shelves should be used correctly. Goods should be placed according to load-bearing shelves. Avoid collision between forklift trucks and shelves. It is best to configure anti-collision Angle, anti-collision bar and other anti-collision equipment. Locking devices must be provided at both ends of each beam of the light shelf so that the beam can be firmly fixed to the column to prevent separation due to upward force. In order to ensure the meshing of the beam and its locking device, the normal operation of the beam lock or the fastening of screws and nuts should be checked regularly during use, and the damaged device should be replaced in time. The installation site should be smooth, without ground depression and inequality. The column feet of light shelf posts should be properly fixed on the concrete foundation, while heavy shelves need to be fixed with tension and explosion-proof screws that are closely connected to the ground. The settlement value of light shelf foundation should be strictly controlled to ensure the normal use of shelf structure. In the design of non-integrated warehouse shelf, attention should be paid to the separation of shelf foundation and building column foundation, so as to prevent the damage of the warehouse shelf structure caused by the force.

Heavy shelf is suitable for all walks of life, low cost, safe and reliable, assembly and disassembly is simple, can be used alone, can also be free to arrange the main and auxiliary shelf form. Heavy shelf can be based on the size of the beam, the thickness of the laminate, the number of reinforcement to determine the load requirements, in the case of the relative length and material selection requirements of the maximum load can reach 2500kg/ layer, generally, the height of the column is not more than 12 meters, attic shelves can be built on the basis of the shelf.

Problems to pay attention to when arranging storage shelves

12-01

Regulations on the natural environment of storage shelves: storage shelves should be in a natural environment of natural ventilation and dry, so as to properly treat paint without rust, paint falling or paint falling areas. Requirements for ground storage shelves: The requirements for ground storage shelves are very important. If the storage rack is supported on the ground as a whole, the electric forklift will remain unified even in its entire state. The shelves remain stationary, so there is no danger of collapse. Overload protection: The net weight of each layer of goods stored does not exceed the greater carrying capacity of the warehouse shelf design concept. Anti-overheight: the floor height and floor width of storage shelves are limited, and the size of pallets and goods should be slightly lower than the net internal space. Avoid collision: The electric forklift should be extremely careful in full operation. Avoid heavy objects and portability: Storage shelves should conform to the standard of light flooring, i.e. heavy objects and lower levels of prior products. Do not use non-standard trays on shelves. When the goods are on the warehouse shelf, the actual operator should not enter the warehouse shelf immediately.
