How to improve the stability of through-type shelves



Through-type racks are storage racks in which forklifts enter the racks to access goods in the form of unit pallets, also known as drive-in racks or corridor racks. This type of shelf occupies less channels, so compared to the commonly used beam type shelf, the overall storage rate of the warehouse is greatly improved to a certain extent. It is mostly used to store goods with a small variety and a large number of single products, such as dairy products, beverages, etc. Wait.
Although the through-type racking saves aisle space and improves the utilization rate of storage space, the through-type rack has poor stability among all types of racks, especially in the horizontal direction, there is no effective force supporting force connection member, but Rely on top pull, be pulled and top beam to ensure the overall stability of the shelf. Therefore, the design height of the through-type rack is usually no more than 10 meters, and the single-direction depth does not exceed 6 positions. How to effectively improve the stability of the through-type rack is also a topic for various shelf manufacturers.
Because the forklift needs to be driven into the aisle when the through-type rack is in use, but a cargo space in the top of the shelf does not need a forklift to enter, so now some shelf manufacturers are designing and installing the through-type rack, in each of the two positions in the top. A crossbeam is added between the pillars under the layer guide rails, and it does not affect the driving-in operation of the forklift at all. In this way, for example, a four-story one-way through-type rack with one-way access has three more horizontal fixed beams in each lane, and a five-story one-way through-type rack with one-way access has four more horizontal beams per lane. The fixed beam, combined with the existing top beam, top pull and being pulled, undoubtedly greatly improves the lateral stability of the through-type rack. Although the increase of the beam increases the cost of the shelf, for example, it is necessary to distinguish the left and right directions of the guide rails in the installation, which brings some inconvenience to the installation. However, considering the overall safety and stability of the shelf, the increase of the beam is still very significant. necessary.
