Introduce a three -dimensional warehouse shelf.4-tier metal utility rolling cart Manufacturing

　　one. What is a three -dimensional warehouse shelf:

　　The three-dimensional warehouse shelves are different from the flat warehouse shelves. The height of the three-dimensional warehouse is generally 7-30 meters, which requires high stiffness and intensity of the shelves and beams. The installation accuracy has a high progress.

　　two. The structure of a three -dimensional warehouse shelf:

　　Most of the three -dimensional warehouse shelf consists of three parts: columns, beams (cow legs), and cable rods

　　three. Category of Libu Shelves:

　　1. Installation method division: welding, prefabricated

　　2. The form of beams: continuous beam type, cantilever beam type

　　3. Divided into the overall and separated formula according to architectural forms.

　　(1) Overall:

　　The building roof is supported by the top of the shelf, and the wall is installed on the side of the shelf. The construction cost is low, earthquake resistance, especially suitable for large automatic warehouses of more than 15 meters

　　(2) Separation

　　The shelves have nothing to do with the building and are independent and separated. Suitable for workshop warehouses, old library technology transformation and small and medium -sized automatic warehouses.

　　4. Classification by building materials

　　(1) Reinforced concrete shelves

　　Advantages: good fire resistance, strong corrosion resistance, simple maintenance.

　　(2) Steel shelf

　　Advantages: small components, high warehouse utilization, convenient production, and short installation and construction cycle.

　　5. Classification of load capacity

　　1) Light carrier: liabilities are 50-100kg;

　　2) Unit negative shelves:

　　The height can reach 40m, the storage capacity can reach more than 100,000 pallet units. Large warehouses are suitable for a general height of 6-15m and the number of storage positions is 100 to 1,000 pallet units. With the continuous improvement of warehousing technology, the access time is getting faster and faster, taking 100 pallet unit access as an example, the average access time is 70s/tray.
