1. Select the storage shelves must choose to fit your warehouse, so before buying, you must advance planning, or let the shelves manufacturers of professional and technical personnel for your tailor-made, so you warehouse utilization rate will increase greatly, will make the possibility of future problems down to a minimum.   2. The stability of storage shelves has always been one of the key issues of warehouse shelf steel structure design. The extensive application of rack steel structure system highlights the importance and urgency of stability research.

FEM model and constraints   When the geometric model is set up, the FEM model needs to be analyzed and the related constraints are set.   1. FEM model: in order to accurately simulate the geometric structure of parts in unit network, preprocessing is meshed by Femap, using 10 node quadrilateral mesh, mesh size 6mm, away from hot spots, and appropriately increasing mesh size.   2. Constraints: the center of the door frame and the drive bridge junction is fixed as a fixed point, restraining the direction

(1) The transport process is not transparent. In the transportation process, in order to reduce the cost, the third party transport enterprises may have the phenomenon of opening the chiller when they close the refrigerator and arrive at the destination in the process of transportation, so they can’t do the whole cold chain. When the goods are delivered, the quality of the goods has fallen, although the surface of the goods is frozen well.   (2) The stored procedure is opaque. Warehousing enterprises cost considerations, there may

The background of the change of the overlap of the portal frame   The production of forklift forklift production enterprises generally have a uniform height of the door frame, but some conditions demand special customers, to meet the actual needs of material handling, forklift will require both high maximum lifting height of H3, and has a door frame lower back height H1, which requires the appropriate standard of door frame the adjustment, to meet customer requirements.   After the design of the overlap degree change, the stress

With the rapid development of the logistics industry, the narrow aisle (VNA) system has been introduced to a rapid growth period after the introduction of the domestic system. For logistics warehouses, the flatness of VNA narrow laneway is a very important factor, because narrow shelving is usually high, and there is a trend of gradual increase in recent years. But the construction process often encounter some problems, such as the owner or lessee of a large amount of money into the VNA system in order to improve warehouse

International general (VNA) flatness specification   1. UK TR34 2003 Edition In recent years, some concepts are easily heard in the industry, such as “super flat floor”, “one kind of floor” or “two types of floor”. It is necessary to point out that these concepts are derived from the levelness classification of the Orienteering floor in the Third Edition (2003) of the technical report of the Concrete Association of Concrete Association of the United Kingdom (TR-34). TR-34 third version of the flat level of the VNA narrow

1. Battery technology The earliest shuttle car is a semi-automatic control mode, and its structure and system are simple. Battery technology is one of the key technologies that affect its application. The working time that can be met by each full charge becomes a bottleneck for shuttle car. While high performance batteries are expensive, the application of shuttle car is very limited. With the continuous improvement of the battery performance and the decline in the price after the production, the shuttle car has been widely used.  

Electronic control system   1. System overview   The electronic control system mainly completes the control task of the conveying equipment in the automation logistics system. The upper and the upper part of the logistics system is connected to the upper computer and the dispatching computer, and the material delivery instructions are received. The device motor is connected down to realize the driving and conveying material detection and identification of the underlying equipment, and complete the process control and material tracking of material transportation. In addition, it

Computer information system   1. System architecture   Computer information system is an online material management system centered on material storage, supply services, linking production, centralized management and information tracking. It integrates logistics support management, material management and warehousing management. It is the information center of management and scheduling. The logistics information system is responsible for the online material process management. By sending the scheduling instructions to the scheduling system, the material storage management and pre-production reserve are guaranteed. It can be connected to the management system
