From the analysis of the big data on the use of storage shelves in the market, we can see that the beam shelf is the most commonly used, economical and safest shelf type at present, with a selectivity ratio of up to 100%. The beam shelf belongs to heavy-duty shelf, which is usually also known as pick-up shelf, location shelf, pallet shelf, etc; Of course, there is another type of storage shelf similar to the beam shelf, that is, the narrow roadway storage shelf. The main frame of narrow roadway rack is basically the same as that of beam rack. At the same time, it can be adjusted up and down arbitrarily with 75mm or 50mm pitch. The frame and beam can also be designed according to the tray and weight of different specifications. Therefore, today, the storage shelves of hegris hegerls should start from the differences between the two, and take a step to analyze the essential differences between cross beam shelves and narrow roadway shelves.
Narrow roadway shelf ｜ beam shelf overall difference understanding:
Crossbeam shelf is a very common shelf mode in various storage shelf systems in China. The structure is simple and effective, and functional accessories such as spacer, steel laminate, mesh laminate, storage cage, oil barrel rack and so on can be added according to the characteristics of storage unit container equipment, which can meet the cargo storage of different unit container equipment. Heavy shelf is a kind of shelf which is widely used. It has good picking efficiency and can store heavy items, but the storage density is low. It has the characteristics of serious bearing, high adaptability, mechanical access and high selection efficiency, but the space application rate is ordinary. It is widely used in manufacturing, third-party logistics and distribution centers. It is not only suitable for multi variety and small batch goods, but also suitable for small variety and large batch goods. Such shelves are widely used in high-level warehouses and ultra-high-level warehouses (such shelves are mostly used in automated plane warehouses).
Narrow roadway shelf is named because the forklift transportation channel of its shelf system is relatively narrow, so it is called narrow roadway shelf. The main body of the shelf system is a beam type shelf system. The difference is that the action guide rail of “three-way stacking forklift” is installed in the air at the bottom of the shelf. Unequal angle steel is generally used for guide rail. The material handling forklift is limited to the special “three-way stacking forklift”. The three-way stacking forklift slides along the established guide rail. The width of the stacking channel of the shelf system is slightly larger than that of the pallet goods, and the high-density storage demand can be completed. At the same time, it inherits all the advantages of the beam shelf system. All the materials stored in the shelf system have very high selectivity. The forklift can store any pallet of goods at any time.
Narrow roadway shelf ｜ beam shelf can be distinguished from the following points:
Different shelf structures
The biggest difference between narrow roadway shelf and beam shelf in shelf structure is guide rail. The cross beam shelf is generally composed of frame, cross beam and other accessories; In addition to the accessories of the beam type shelf, the narrow roadway shelf also has one more accessory than the beam type shelf, that is, the guide rail, which is also the biggest difference between the two structures.
Different shelf channels
Generally speaking, the channel is designed according to the size of the warehouse site, different goods and other detailed requirements. For this, the channel of narrow roadway storage shelf and beam shelf is naturally different. The roadway width of narrow roadway shelf is much smaller than that of ordinary beam shelf, generally about 1600-2000mm. The difference between the narrow roadway storage shelf and the beam shelf in the roadway channel is that because the narrow roadway shelf roadway is relatively narrow, the forklift used is generally a three-way forklift. For the beam shelf, the narrow roadway shelf does not need to reserve the floor area and turning width required by the traditional forklift.
Different storage facilities
Generally speaking, each storage shelf has its own special equipment and facilities, and the same narrow roadway storage shelf and beam shelf also have their own special equipment and facilities. Special forklifts are required when goods are stored and stored in narrow roadway shelves, that is, our common three-way stacking forklifts; There is no channel for cross beam shelf forklift, so the requirements for forklift are not very high. As long as it can reach the lifting height of goods and meet the requirements of channel, the commonly used forklift is generally forward moving battery forklift or balance weight battery forklift.
Different warehouse utilization
The difference between the two also lies in the difference of warehouse utilization rate: that is, because the channel of narrow roadway shelves is small and the height is high, it is usually more than 10m, which is mostly used for higher warehouses, so the warehouse utilization rate of narrow roadway shelves can reach 50%; The cross beam shelf channel is large, and the overall height is not very high. For this, the utilization rate of the warehouse is smaller than that of the narrow roadway shelf, which can only reach 35% – 40%.
Guide rail guidance system
After the installation of narrow roadway shelves, a guide rail with a height of about 200mm is used as the guide system of forklift to reduce the damage to the shelves caused by forklift drivers due to human factors. The requirements of beam shelves for drivers are lower.
Different high density storage
When storing goods in narrow roadway shelves, the three-way stacking forklift will slide along the specified guide rail route, because the stacking channel width of the shelf system will be greater than the width of pallet goods, so high-density storage can be easily realized.
Here, haigris hegerls storage shelf manufacturer needs to say more that the basic structure of cross beam shelf is similar to that of narrow roadway shelf. Both shelves are generally operated by forklift. Cross beam shelves and narrow roadway shelves are used to store pallet goods, which belong to heavy shelves and cargo space shelves. Each group of pallet cargo space of the shelf is basically the same, and there are similarities in use, which should be determined according to the attribute of goods and the degree of container loading. The above is the difference between cross beam shelves and narrow roadway shelves summarized by Hebei hegris hegerls storage shelf manufacturer.
