Structural composition: mainly composed of columns, beams, cross braces, slant support and other components. The column adopts cold bending forming technology, with multiple cross-sections, large inertia distance, and strong impact resistance; The crossbeam is generally welded from two specially made C-shaped lap welded beams, and is connected to the column with ear safety pins to prevent external impact and detachment. characteristic Strong load-bearing capacity: The load-bearing capacity of each layer is usually between 500kg and 5000kg, and some customization can reach up to 10 tons, which can store heavy industrial parts, bulk commodities, etc. Height flexibility: The crossbeam can be freely adjusted up and down with a step distance of 75mm or 50mm, and the number and height of floors can be flexibly set according to needs. The height of a single column can reach 12 meters or even higher. Convenient storage and retrieval: Goods storage and retrieval are not limited by order, and can achieve first in first out. With the cooperation of forklifts and other equipment, it can quickly complete the inbound and outbound operations of goods. Safe and reliable: The combination structure prevents instability caused by loose bolts, and can also be equipped with column foot guards, anti-collision bars, etc. to reduce the risk of forklift collisions. Cost effectiveness: Simple structure, easy installation and disassembly, low maintenance cost, and long service life, which can effectively reduce the storage cost of enterprises. Application scope: Widely used in industries such as electronics, home appliances, communications, computers, instruments, furniture, clothing, automobiles, tires, supermarkets, etc., suitable for storage modes such as pallet storage and forklift access.
