The through shelf is also known as the corridor shelf or the driving shelf. The through shelf adopts pallet access mode, which is suitable for the storage of goods of small variety and large batch. In addition to the cargo space close to the passage, as forklift trucks need to enter the shelf to access cargo, it is usually recommended that the single-side pickup should not exceed 7 cargo depth. In order to improve the speed of forklift truck operation, the guide track can be selected according to the actual needs. Compared with the cargo shelf, the utilization rate of storage space of the through shelf (driving shelf) can be increased by more than 30%. The through shelf (driving shelf) is widely used in cold storage and food and tobacco industry.

1. Standards of through-shelf industry
There is no uniform implementation standard for shelves in China. Often manufacturers waste a lot in material selection and design, and occasionally design undertakings will occur.
Loading and safety levels are not up to the standard, forming hidden dangers in actual operation.
The Rules for Design and Material Selection of Through-type Shelf and Installation and Inspection Standards of Through-type Shelf, formulated by Changzhou Changtong Logistics Equipment Co., Ltd., have been accepted by the project and are expected to be popularized throughout the country.

2. Characteristic of through shelf
1. On the supporting guide rail, the pallets are stored in the depth direction, one after the other, which makes the pallets stored in the depth direction.
High-density storage is possible.
2. Goods are accessed from the same side of the shelf, first stored, then taken, and then stored. Balanced weight and forward forklift trucks can easily drive into the shelf to access goods without occupying multiple channels.
3. This kind of shelf is suitable for storing large quantities and few varieties of through-type shelves (driving shelves) with integral stamping/rolling technology. It has strong bearing capacity and beautiful appearance.
The total depth of the shelf in the wall area is generally better controlled within 5 pallet depths. The total depth of the shelf in the middle area is generally better controlled within 10 pallet depths, so as to improve the efficiency and reliability of forklift truck access.
The stability of through-type shelf system is weaker in all kinds of shelves, so the shelf should not be too high, generally within 10 meters. In addition, the system also needs to install a pulling device. This system has dense shelf arrangement and high space utilization. It is suitable for storing a small variety of similar goods in large quantities. Goods can be stored and taken out from the same side or from one side to the other.
1. Driving-in shelves are also called corridor shelves or through shelves.
2. Forklift trucks can be driven into the laneway to store pallets.
3. Access mode is FIFO or FIFO: from the same side in and out for FIFO, from one side in and out for FIFO.
4. It can greatly improve the utilization rate of space.

3. Composition characteristics of through cargo structure
Storage shelves and through shelves are multi-portal, pallet unit chemicals which are connected by lattice column edge succession, one by one stored on cantilever beam along the depth direction. The structure of the die holder can share the forklift truck operation channel and goods storage space, and greatly improve the space and area utilization ratio of the warehouse. However, the goods in the same operation channel can not be first-in-first-out. It is suitable for the goods in large quantities, small varieties or operation channels to flow to the same customer's goods storage together, such as beverages, dairy products, tobacco, cryogenic storage. Standard specification of household appliances, chemical industry, clothing and other industries. According to statistics, driving shelves can achieve maximum storage density, the most effective utilization of space can be increased to 90%, and the utilization of site area can reach more than 60%.

4. Advantages of through shelf
1. Goods storage channel is also forklift truck storage and transportation channel, which is a form of shelf with high storage density.
2. It is usually used for storage of goods with few varieties but large batches and low requirements for picking goods.
3. The effective storage capacity of warehouse can be increased by more than 100% with the elevation height of common forklift truck and the number of storeys on corridor shelves as three-storey goods. By contrast, the investment cost can be controlled and the benefit can be improved significantly. From the global storage cost, the investment cost can be offset by the increase of storage capacity benefit in three years.
4. Goods follow the principle of "first in, last out" and are suitable for most handling machinery storage operations.

5. Use method of through shelf
Although we all know how to use the drive-in shelves to help enterprises improve economic efficiency, but only pay attention to this point is not enough, we need to pay attention to how to better use the drive-in shelves to maximize economic efficiency.
Better use of through-shelf needs to pay attention to, in the design of a new warehouse or the transformation of an existing warehouse, then it is necessary to review and study the characteristics of the system applied in the warehouse, such as driving shelf can achieve maximum warehousing capacity in the smallest space, then you can choose this economic logistics scheme.
When using through shelves, loading and unloading should be carried out from one side, which can effectively improve the time efficiency.
The through-type shelf is a continuous whole shelf without channel partition. On the support rail (bracket beam), pallets are stored in depth direction, one by one, which makes high-density storage possible. Driving-in shelves are suitable for the storage of goods with few varieties and large quantities. They are often used to store large quantities of similar goods. They have high space utilization. They are suitable for the occasions of high storage space cost in food industry, chemical industry, clothing industry, cold storage and so on. Their storage cost per unit site is relatively low.
Through shelves can be divided into one-way and two-way arrangement according to the direction of picking up goods. The total depth of one-way (wall area) shelves is best controlled within 6 pallet depths, and the total depth of two-way (middle area can be picked up on both sides) shelves is best controlled within 12 pallet depths, so as to improve the efficiency and reliability of forklift truck access (forklift truck is a sustainable operation mode of "lifting and hitting" in this kind of shelf system. The forklift truck is easy to sway and crash into the shelf, so it is very important to consider the stability adequately. The stability of this kind of storage system is weak, and the shelf should not be too high. Usually, it should be controlled within 10 meters. In order to strengthen the stability of the whole shelf system, besides the larger size and type selection, the reinforcement device should be added. Single pallet cargo should not be too large and overweight. Usually the weight should be controlled within 1500KG, and the pallet span should not be greater than 1.5 meters. Forklift trucks are usually equipped with forward-moving battery forklift trucks or balanced heavy battery forklift trucks. Shanghai Sloan Logistics Equipment Co., Ltd. is a professional and shelf manufacturer in Shanghai. We mainly produce various warehouse shelves, logistics shelves, supermarket shelves, material shelves, mold shelves, light shelves, heavy shelves, Shanghai shelves, Shanghai warehouse shelves, material shelf manufacturers, Shanghai mold shelves, etc.
Because of the intensive storage of goods and the high requirement of stability, the through shelf requires relatively more shelf accessories. Through the connection between the parts and the shelf pillars, the goods can be safely and intensively stored on the bracket beams to maximize the use of space. The fittings of driving rack include: bracket (main connector between bracket beam and rack column, single side and double side), bracket beam (main supporting shelf for cargo storage), top beam (connecting fastener for rack column), top pull (connecting fastener for rack column), back pull (connecting fastener for rack column, when used for one-way arrangement of rack), foot guard (protecting part for rack front), rail guard (fork). The shelf protector when the vehicle enters the roadway, etc.

6. Daily maintenance of through shelves
Daily maintenance and maintenance of shelves also reflects the top priority of a shelf factory service. TMCC regularly maintains and maintains customers'high shelves to ensure efficient storage and safe use of shelves.
(1) Clean and timely discover the mechanical deformation of shelves through external force collision and timely replace the safe and stable shelf parts. In line with the first safety criterion, in the cleaning process, timely discovery of potential safety hazards, timely handling, ensure safe and efficient storage.
(2) Professional horizontal stereo positioning tools are used to correct the shelf condition, and then effectively correct it to ensure the shelf bearing capacity and safety.
(3) Strictly enforce the rules of safe use, no overload, over-line location, over-storage density, to ensure the safety performance in the storage process.
(4) The maintenance cycle is one year.
(5) Maintenance includes the routine contents of fastener tightness measurement, column vertical measurement, damaged parts measurement, etc. If the column is bent or broken, it needs to be measured as a whole. Maintain the system according to the measured data.
