Is It Appropriate for the Rack Manufacturer to Undertake the Four-way Dense Warehouse Project?
As the cost of industrial land keep rising, coupled with the increasing cost of employment, enterprises require intelligent warehouses, maximum storage capacity, automation (unmanned), and information technology. Four-way shuttle dense warehouses are becoming the mainstream form of intelligent warehousing due to their flexibility in storage density, storage categories, and storage efficiency.Racks, as the most basic, common and largest shipment product in the warehousing and logistics industry, make it easier for rack manufacturers to obtain requirement information for four-way dense warehouses. In addition, racks account for a considerable proportion in four-way intensive warehouses. Rack manufacturer owners tend to believe that intelligent systems have high profits, and they are already overwhelmed by loaning from system integrator for rack. Therefore, some rack manufacturer owners began to undertake intelligent warehouse projects by themselves, taking charge of the rack part themselves and outsourcing other systems.So is it really appropriate for the rack manufacturer to undertake the four-way dense warehouse project? Let's talk about the disadvantages! 1.Main business: Every profession has its own specialty. The four-way dense shuttle warehouse project is not the main business of the rack manufacturer. Less energy and research have been invested in it. In the era of involution in every industry, it is even more impossible to make money beyond one's ability.2.Technology: The rack manufacturer only has technical personnel for the rack part, and no professionals related to the intelligent warehouse. The early communication and solution design require the assistance of other partners. Since it is usually the rack manufacturer’ salesperson contacts the end customer, so deviations are inevitable when the information is conveyed, causing disputes during the later construction and acceptance. In addition, the rack manufacturer does not have a unified standard specification for the entire system. If a problem is encountered during the implementation process, it is impossible to determine which party is responsible, and there is a risk of passing the buck.3.Price: When competing for four-way dense warehouse projects, rack manufacturers often adopt a low-price strategy because they are not qualified enough. Once they get the project, they will reversely control the procurement cost and subcontract to some less professional manufacturers or individuals at ultra-low prices. Whether it is the equipment or technology, it will be greatly discounted, and it is difficult to control the reliability of the project from the system perspective.4.Competition: As a supplier of system integrator, rack manufacturers provide system integrator with various automated racks on the one hand, and compete with system integrator for intelligent warehouse projects on the other hand. Conflicts are bound to arise between them, causing the previous integrator customers to re-select supporting rack manufacturers .5.Implementation: The implementation of intelligent warehouses often adopts project management system. The project manager coordinates and plans the implementation progress of the entire project, and handles some emergencies that may occur at any time. The rack manufacturer does not have a similar qualified project manager, and the implementation process may be often a mess, with chaotic procedures and frequent rework. It is hard to determine who is at fault when encountering problems, which leads to delays in construction progress and additional expenses for the user. Once the user is angry and improper handling by the rack manufacturer, it often leads to conflicts among the implementation teams of all parties, and the breakdown of cooperation, resulting in inherent deficiencies in the project or the final failure.6.After-sales service: A complete intelligent system cannot be without after-sales service. The rack manufacturer implements the project basically by relying on a temporary external team, not a long-term partner. Once the project is over, all parties will also disband. If time is a little longer, once you encounter after-sales problems, you may not even be able to find the previous implementation personnel, let alone the technical information related to the project. The project is used with inconveniences, and in a few years it will face huge project transformation (transformation projects are more difficult than implementing a new project).In summary, we recommend that users carefully consider the following points when selecting a supplier: Does the supplier have its own core equipment and core technology? Does the supplier have its own technical standard system and implementation team? Does the supplier have the ability to implement and control the entire project? Does the supplier have multiple self-completed and accepted projects?

What Kind of Factory is Suitable for the Four-way Intensive Warehouse?
From the perspective of height: the lower the factory height, the more suitable it is for the four-way intensive warehouse solution because of the high space utilization rate. In theory, we do not recommend designing a four-way intensive warehouse for the factory higher than 24 meters, mainly because after-sales service is very difficult. If this problem can be solved in the future, the same height as the stacker can be achieved.

Guided by technological innovation, it has obtained two inventions of core technologies Patents, to provide customers with increasingly optimized high-intensity warehousing automation, information, and intelligent system solutions. The company"s core equipment, the 4D vehicle, adopts mechanical jacking, is thin in thickness, and has an intelligent program, and has realized a parameterized debugging mode. The main track and secondary track structure designed by Nanjing 4D shuttle has better force resistance, saves space and lower cost.Design and planning of the steel structure of the pallet 4D shuttle three-dimensional warehouse shelfThe difficulty in the design and planning of the steel shelf structure of the pallet 4D shuttle three-dimensional warehouse lies in: the design and optimization of the pallet 4D shuttle steel shelf structure in the warehouse, and the pallet 4D shuttle three-dimensional warehouse is mostly based on existing buildings. And planning, on the basis of fully considering the planning of storage functional areas and meeting the requirements of functional configuration, complete the configuration, planning, design and verification of the pallet 4D shuttle three-dimensional warehouse.In considering the planning and design of the pallet 4D shuttle three-dimensional warehouse, the types of goods to be stored and the unitized size series, the specifications and dimensions of the pallet 4D shuttle trolley, the height of the building floor in the warehouse area, and the load-bearing and Factors such as uneven ground settlement requirements, construction and operating costs, operating efficiency and reliability configuration of storage and handling equipment, etc., construct a structural model and force system analysis factors for a pallet 4D shuttle high-position steel shelf structure, and a pallet 4D shuttle steel shelf The structure adopts the limit state design method based on probability theory, and uses the partial coefficient design expression for design and calculation, in which the load-bearing members are designed according to the limit state of bearing capacity and the limit state of normal service; , structural form, stress state, connection method, steel material and thickness, working environment and other factors are considered comprehensively, and non-load-bearing components are mainly set according to the structural requirements of steel shelves.Among them: the column of the pallet 4D shuttle type three-dimensional warehouse shelf is checked according to the two-way bending member, the influence factors of the holes on the front or side of the column need to be considered, and the calculation of the strength design value of the cold bending effect of the column cross-section pass pattern should also be verified. Methods, etc. The content of the checking calculation includes the calculation and checking of the strength, stiffness and stability of the shelf column and its components. The stability checking calculation includes the multi-element requirements such as local buckling, distortion buckling and overall bending-torsion buckling.

Concept and practical application of FIFO
In the warehouse, there is a principle of "first in first out". As the name suggests, it refers to the goods with the same code "the earlier the goods enter the warehouse, the earlier going out of the warehouse". Is that the cargo that enters the warehouse first, and it must be sent out first. Does this mean that the warehouse is only managed based on the receiving time of the goods and has nothing to do with the production date? Another concept is involved here, which is the shelf life of the product.The shelf life usually refers to the period from manufacturing to expiration. In the warehouse management, the same SKU products will successively enter the warehouse with a new production date. Therefore, in order to avoid deteriorating products in the warehouse, when shipping, it will set priority to send out those products that enter the database early. From this, we can see the essence of advanced first, which is usually judged according to the time entry time, but now it has become judged by the shelf life of the product. In other words, the advanced out -out of the storage management, literally, is to first ship the goods that enter the warehouse first, but in essence, the goods that are closest to the expiration date first.In fact, the concept of advanced first was born in the warehouse of the manufacturing company. At that time, there were not many products in the product. Each warehouse only received the products offline of the local factory. The principle of delivery is not a problem. However, with the gradual increase in product types and the further expansion of sales, some customers" business has expanded to all parts of the country. Factions of various products have been established nationwide to save logistics costs. The warehouses that were originally served only for offline products, the functions became stronger and stronger, and became regional distribution centers (DC). The distribution center warehouse in each region starts the full -product layout. Not only the products that store local factories, they will also accept the arrival of other factories and other warehouses from the country. At this time, you will find that the goods that are allocated from other warehouses are the warehouses that enter later, but the production date may be earlier than some of the products in the existing inventory. At this time, if it is still literally, it is obviously meaningful to be shipped according to "advanced first".Therefore, in the modern warehouse management, the essence of "advanced first" is actually "failed first", that is, we do not judge according to the time of entering the warehouse, but to judge based on the failure period of the product.As the earliest domestic companies in China to study the 4D dense system, Nanjing 4D Smart Storage Equipment Co., Ltd. provides customers with increasingly optimized high -dense storage automation, information, and intelligent system solutions to customers. The company"s core equipment 4D shuttle can meet the requirements of "advanced first". It adopts mechanical top -up, thin thickness, and intelligent program, which has achieved parameter debugging mode. After three years of research and development and 3 years of project implementation experience, there are nearly ten project cases in Nanjing Fourth, and most of them have been accepted, which provides a guarantee for the quality of the product.In addition to the assistance on the equipment, the efficient system is also indispensable. In the WMS system, SKU management does not require variable attributes, and the encoding of inventory goods can be directly adopted by the SKU code. The advanced implementation of SKU management is implemented by the warehouse operation management of the warehouse. In addition, in the management of warehousing, it is necessary to set this principle in the system. The storage rules of the ranking are best to store only one code batch product in the same ranking. Regularly screen the products of the inventory according to the production date. For products that are about to expire (failure or stop sale), the detection and treatment should be done early.

Nanjing 4D Intelligent 4D shuttle’s advantages and project implementation
As a new solution for three-dimensional warehouses, the 4D shuttle has attracted much attention from customers. Compared with the stacker, it is more flexible, intelligent and cost-effective. With the diversified development trend of the warehousing and logistics industry and the broad requirements of cost control, more and more users will choose the 4D shuttle system.The traditional laneway stacker solution is mostly used in rectangular warehouses, while the 4D shuttle can be constructed in a modular form even in special-shaped warehouses, and has stronger adaptability to warehouses. At the same time, multiple 4D shuttles can be used on one floor to increase the system"s in-out rate. The rated load of the 4D shuttle is generally within 2t, and it is suitable for use in three-dimensional warehouses below 25 meters. It can move flexibly in four directions, front, back, left and right, and reach any position of the vertical warehouse to realize the sorting and loading of goods.Nanjing 4D Intelligent Storage Equipment Co., Ltd., as a professional 4D intensive storage system integration company in China, has been focusing on 4D intensive storage system solutions for many years. The core equipment, 4D shuttles and core technologies are independently developed and produced.In August 2023, another 4D shuttle project of 4D Intelligence is being launched in Xinjiang. Engineers combined warehouse environment, intensive storage, and warehouse input and output efficiency to design the optimal plan and establish two constant-temperature material storage warehouses, One 7-tier shelf, the other 3-tier shelf, utilizes 2 sets of 4D standard shuttles and 2 sets of elevators, providing a total of 1360 vaccine storage positions. The on-site project commissioning work has come to an end and has entered the stage of trial operation. The entire project process is implemented in strict accordance with standardization, and each project link is controlled with high standards. After the project is completed, the storage of goods will be more flexible and efficient. According to the development needs of customers, the efficiency of storage and storage can be easily improved by increasing the number of 4D shuttles. In addition, more storage solutions are provided according to the complexity of cargo specifications to achieve single-deep, double-deep, and multi-deep. Combined mode. Real-time information, real-time monitoring, and WCS scheduling are equipment operations, real-time monitoring of the 4D shuttle coordinate position, speed, power and other status, which can be operated and viewed at any time. In contrast, if the stacker solution is used, the storage capacity will be greatly reduced, and the project cost will be about 30% higher. Therefore, considering all aspects, the 4D shuttle is a more reasonable choice to realize intelligent intensive storage for customers.

What are the advantages of 4D automated shuttles to shuttle carrier system?
With the development of the production economy, the scale of many enterprises has rapidly expanded, product types have increased, and businesses have become more complex. Coupled with the continued rise in labor and land costs, the traditional warehousing methods cannot meet the current needs of enterprises for precise management. Therefore, Warehousing automation and intelligent transformation have become inevitable trends.Chinese smart warehousing technology is becoming more mature, and there are currently a variety of robots and solutions on the market. Among them, the 4D shuttle automated warehouse and the shuttle and carrier system automated warehouse are high-density storage solution. They are with the same racking types and have received widespread attention. So why more and more people tend to choose 4D dense storage solutions, and what are the advantages?The automated shuttle and carrier system uses a combination of pallet shuttles and carriers to complete operations. The carriers bring the pallet shuttles to the corresponding lane and releases them. The pallet shuttles complete the work of storing and retrieving goods alone, and then carriers receives the pallet shuttles in the main track. The 4D automated shuttle warehouse is different. Each 4D shuttle can work independently and perform layer-changing operations on the main track, sub-track and with the elevator. Therefore, it is like an improved version of the shuttle and carrier system. The 4D shuttle can operate in four directions, making transportation more flexible and more efficient. In terms of cost, shuttle and carrier system is also higher than that of automated 4D shuttle system.The shuttle and carrier system has achieved dense storage and full automation, but its structure and composition are complex, with pallet shuttle and carriers, which results in its low safety and stability. Maintenance of this system is cumbersome and expensive. The 4D shuttle is like an intelligent robot. It can be connected to the WMS system using a wireless network. A 4D shuttle can complete tasks such as picking up, transporting, and placing goods. Coupled with elevator, the 4D shuttle can reach any cargo position to realize horizontally and vertically movements. Combined with WCS, WMS and other technologies, automatic control and management can be realized.We can see that the 4D shuttle warehouse has many advantages over the automated shuttle and carrier warehouse, and it is the preferred solution for customers.The 4D intelligent dense storage system of Nanjing 4D Intelligent Storage Equipment Co., Ltd. is mainly composed of six parts: dense shelves, 4D shuttles, conveying equipment, control systems, WMS warehouse management software, and WCS equipment scheduling software. It has five control modes: remote control, manual, semi-automatic, local automatic and online automatic, and comes with multiple safety protection and early warning functions. As an industry pioneer, our company is committed to the innovation, research, development and application of high-density storage logistics automation, informatization and integration technologies for users, providing users with equipment development and design, production and manufacturing, project implementation, personnel training and after-sales services and other one-stop services. The 4D shuttle is the core equipment of the intensive 4D intelligent warehousing system. It is completely and independently developed and produced by Nanjing 4D Intelligent Storage Equipment Co., Ltd. With the diversified development trend of the warehousing and logistics industry and the broad requirements for cost control, more and more users will choose the 4D shuttle system.

What are the advantages of a 4D shuttle versus a radio shuttle?
As a new solution for three-dimensional warehouses developed from traditional shuttles, the 4D shuttle has been favored by customers since its birth. Compared with the radio shuttle, its operation is more flexible, stable and safe. In addition to the basic shuttle, racks and forklifts, it can also be combined with automation equipment and warehouse management systems to achieve fully automated storage.Radio shuttles originated in Japan, and countries in Europe, and were widely accepted in the market by 2000 for its relatively matured technology. The 4D shuttle is a relatively big upgrade over the radio shuttle. It has significant advantages and is suitable for both low-flow and high-density storage and high-flow and high-density storage and picking.The most obvious difference between a radio shuttle and a 4D shuttle is that the former can only travel in the forward and backward directions, making insufficient use of irregular terrain. The latter can travel in four directions, which improves the flexibility of operations, has high adaptability, and improves space utilization.In addition, the layout of their conveying systems is also different. Radio shuttles require main aisle for carrier cart on each floor, while the layout of 4D shuttles can be adjusted according to customer needs. The radio shuttle can solve problems such as positioning, power supply, and communication through layer-changing technology, but it does not have the ability to move laterally and has poor flexibility. The 4D shuttle can not only solve the problems of lateral movement and layer changing, but also more effectively solve complex problems such as lane switching, shuttle obstacle avoidance, shuttle dispatching, etc. It will automatically stop and respond when encountering obstacles or reaching the end of lane. It choose the best walking route, and have a greater scope of application and flexibility.Nanjing 4D Intelligent Storage Equipment Co., Ltd. focuses on system solutions for dense storage. The core equipment 4D shuttles and core technologies have been independently developed and produced for many years. Guided by technological innovation, it provides customers with increasingly optimized high-density warehousing automation and information. , Intelligent system solutions. Provide one-stop services from R&D, production, project implementation, personnel training to after-sales of core equipment and technologies.We believe that with the diversified development trend in the warehousing and logistics industry and the broad requirements for cost control, more and more users will choose the 4D shuttle system.
