Heavy-duty storage shelves are commonly used shelves, providing 100% accessibility and little picking efficiency. However, the storage density of such shelves is relatively low, requiring more channels (Aisle). Generally, it can be divided into traditional channel, narrow channel and ultra narrow channel according to the width of its access channel. The latter needs to be used with appropriate stacker.

1. Introduction of Heavy Storage Shelf
Heavy storage shelves, also known as cross-beam shelves, or space shelves, belong to pallet shelves, and are the most common shelf form in various domestic storage shelf systems. The fully assembled structure in the form of column sheet and cross beam is concise and effective. According to the characteristics of storage unit assembly equipment, such as: partition, steel layer (wood layer), wire mesh layer, storage cage guide rail, oil drum rack and other functional accessories can be installed. It can satisfy the storage of goods in the form of different unit assembly equipment.
Firstly, it is necessary to carry out the work of assembling and unitizing, i.e. packing goods and their weight characteristics, to determine the type, specification, size of pallets, single pallet weight and stacking height (the weight of single pallet is generally less than 2000 kg), and then to determine the span, depth and spacing of unit shelves, and to determine the cargo according to the effective height of the lower edge of the warehouse roof and the maximum forklift height of forklift truck. The height of the rack. The unit shelf span is generally less than 4 m, the depth is less than 1.5 m, the shelf height of low and high warehouses is generally less than 12 m, and the shelf height of super high warehouses is generally less than 30 m (such warehouses are basically automated warehouses, and the total shelf height is composed of several columns within 12 m).
In this kind of warehouse, most of the low and high warehouses use use use use with forward-moving battery forklift, balance battery forklift, three-way forklift truck for access operations. When the shelf is low, also can use electric stacker, super warehouse with stacker for access operations. This kind of shelf system has high space utilization rate, flexible access and convenient computer management or control, which can basically meet the requirements of modern logistics system.
It is widely used in manufacturing industry, third party logistics and distribution center. It is not only suitable for multi-variety and small-batch goods, but also suitable for small-variety and large-batch goods. Such shelves are mostly used in high-level warehouses and super-high warehouses (such shelves are mostly used in automated warehouses).

2. Main Characteristics of Heavy Storage Shelf
The goods are usually stored on the shelf after being packed by pallets, storage cages and other units.
It is one of the most common and widely used shelves, suitable for most warehouses or products.
It has 100% arbitrary picking characteristics. Handling machinery such as forklift trucks can reach any cargo location for storage operation, storage operation is convenient and fast!
Storage operation with mechanical handling equipment.

3. Production Technology of Heavy Storage Shelf
The specifications of heavy shelf columns are 55 x 47 x 2.0mm special shelf column profiles. It is made of high quality strip by leveling, rolling by automatic rolling mill, punching by punch and cutting according to the specified height of customers. Cold-rolled P-shaped closed beams are used for crossbeams. The specifications are: 50 *30, 64 *40 and 80 *50. It is a standard product for shelf production in cold bending industry. After purchasing, according to the size of customers, the welding rack is connected with the special column grasp, and the grinding can form a semi-finished product.
Heavy shelf laminates are made of high quality cold plate (SPCC) by leveling, longitudinal shearing, bending forming and welding reinforcement.
After heavy shelf columns and laminates are processed into semi-finished products, spraying can be carried out with shot peening, rust removal and oil removal. Packing and delivery after completion.
4. Characteristics of Heavy Storage Shelf
Heavy storage shelves are low cost, safe and reliable, easy to assemble and disassemble. They are suitable for manual access, and each layer standard can effectively carry more than 800kg. They are suitable for manual access of box-type goods, or for loading scattered heavy goods with parts boxes and turnover boxes.
