Description

Technical Field

[0001] This invention relates to the field of P-type rack beam technology, specifically to a production equipment for P-type rack beams and the P-type rack beam profile. Background Technology

[0002] P-type rack beams are a type of heavy-duty racking, and are widely produced and sold by warehouse racking manufacturers. Because P-type rack beams allow for easy picking of goods stored in any location, they are also known as picking racks, pallet racks, or pallet racks. P-type rack beams are stable, sturdy, durable, and easy to assemble and disassemble, making them suitable for any type of goods. They are widely used in e-commerce logistics, bonded warehouses, third-party logistics, and factory and mining warehouses, and are the most commonly used racking in automated storage and retrieval systems (AS / RS).

[0003] P-type racking has a simple, safe, and reliable beam structure that can be freely adjusted and combined. The order of goods entering and leaving the warehouse is not restricted. The uprights of the P-type racking beam are connected by bolts, including columns, horizontal braces, and diagonal braces. The uprights are inserted into C-shaped welded beams to form the racking structure, secured with safety pins, resulting in a simple and reliable structure. The load-bearing capacity of the P-type racking beams can be determined by the size of the uprights and beams, featuring a large moment of inertia, strong load-bearing capacity, and strong impact resistance. A single upright of the P-type racking beam can reach a height of 12 meters. Pallet racking is highly versatile; mold racking, mezzanine racking, automated warehouse racking, and even special oil drum racking can be built on the basis of pallet racking. P-type racking beams effectively increase warehouse storage height and improve warehouse space utilization. Suitable for storing various types of goods; the P-type racking beams have a safer appearance, preventing forklift collisions, and can be further reinforced with upright guards and anti-collision bars. For enhanced safety, additional equipment such as beam dividers, shelves, and wire mesh crossbeams can be installed on the beams. P-type racks are inexpensive, easy to install and operate, and simple to locate goods, making them suitable for any type of moving equipment, thus becoming the most widely used type of rack. P-type rack beams can also be fitted with shelves, which can be made of steel plates, melamine boards, or wire mesh to accommodate pallets of different sizes.

[0004] However, traditional P-type rack beams have the following disadvantages:

[0005] The straightness of the beams in traditional P-type shelving cannot meet customer needs, requiring multiple cutting and polishing processes, resulting in high production costs. Summary of the Invention

[0006] The purpose of this invention is to provide a production equipment for P-type rack beams and the P-type rack beam profile thereof, so as to solve the problem mentioned in the background art that the straightness of traditional P-type rack beams cannot meet the needs of customers, requiring multiple cutting and polishing, resulting in high production costs.
