Warehouse racks can be divided into three categories according to the load, namely light warehouse racks, medium warehouse racks and heavy warehouse racks. These three types of shelves have a similar structural composition, and the main components are beams and column pieces. However, although the structures of these three types of shelves are similar, the functions are still somewhat different.
Light-duty racks generally refer to shelf-type racks, also called laminate racks, which are mainly used for manual storage and retrieval of goods, and are suitable for storing relatively small and light goods. The carrying capacity is lower than that of medium-sized racks and heavy-duty racks. The advantage of light-duty racks is that the materials used in the racks are relatively light, which leads to their own weight is relatively small and can be easily moved. For companies that need to move the racks frequently, this is a very Good choice.
The load-bearing capacity of medium-sized racks is between light-duty racks and heavy-duty racks. They are assembled by columns, beams, and laminates. An independent group has two columns. Such racks are called main racks. The entire rack is not connected by bolts. Easy to install and disassemble. The main and auxiliary connection form is adopted, and the stability is strong. Relative to light-duty shelves, some heavier goods can be placed, but the daily storage and retrieval still mainly requires manual handling. Medium-sized shelves are not suitable for storing complex goods with many specifications, which will greatly reduce work efficiency.
The load-bearing capacity of heavy-duty warehouse shelves is very large, and the general load-bearing capacity is 500kg to 3000kg. It is also a common type of shelf in large warehouses. This kind of shelf mainly stores heavy goods and cannot be accessed by manual access alone. It usually adopts mechanized access operations, such as forklifts. There are many types of warehouse heavy-duty racks, such as beam racks, through racks, gravity racks, cantilever racks, mold racks, etc. The structure of different types of racks is very different, and their respective load-bearing ranges are also different.
