Acid pickling and phosphating is an important step in rack pretreatment, which has a great impact on the quality and life of racks.   Pickling and phosphating is a very complicated and laborious process, and the pre-treatment of some large factories is the whole day of pickling and phosphating. At present, because of the cost, because of environmental protection, many factories no longer carry out this step of pickling and phosphating.   The first step is degreasing. Degreasing is done with a high-temperature alkali solution, which is to

With the continuous development and maturity of rack industry technology in China, gravity racks have been used in domestic warehouses. Although the construction cost of gravity rack warehouses is relatively high, the application rate of gravity rack warehouses in China’s small and medium-sized enterprises is not very high, but its development prospects are good, and the future demand will be growing.   Gravity racks are designed with roller pedestals, properly tilted, driven by the weight of goods, trays are stored densely and in the best physical cycle

A. Forklift tonnage configuration. Mainly have: 1.5T, 1.8T, 2T, 2.5T, 3T; choose that kind of purchase configuration needs to see the weight of goods, and the highest fork height. As the height increases, the maximum safety of forklift truck decreases. For example, a 2T battery forklift truck 5 meters high can fork up to 2T when working at low position, but when fork up to 5 meters high, its safe weight may be only 800KG, or up to 1000KG. Exceeding this weight may be dangerous due to overload.

Because the collection of seismic data and the determination of parameters of equipment are far more complex than those of civil buildings, the research on seismic resistance of equipment is limited to nuclear equipment, electric power equipment and other important equipment.   At present, there is no aseismic standard or industry standard for logistics equipment in ASRS. It mainly depends on the system integrator to make more considerations in the design and planning. The main consideration is how to design the parts connected with the logistics equipment

The drive in rack is composed of frames, bracket beam, top beam, middle beam, top tie, back tie and so on. This kind of rack is suitable for the storage mode with relatively few varieties and integral whole. Because the forklift truck can drive into the storage area only by arranging the aisle, the warehouse utilization rate is high, and it is mostly used in cold chain logistics, beverages, food, dairy products and other fields.   Drive in rack system has the typical characteristics of FILO. Forklift trucks are usually operated in

1. Civil built cold storage. At present, the large-scale cold storage built in China is basically civil-style cold storage. The building is usually multi-storey, reinforced concrete structure. The cold storage is assembled with PU sandwich cold storage plate inside the structure or sprayed around by PU.   2. Fabricated cold storage. In the past few years, the assembled cold storage is generally used in small-scale assembled cold storage in China. In recent years, with the wide use of steel structure in many large-scale buildings, large-scale steel structure
