1. Brief introduction of storage heavy shelves
Overview of heavy shelf is the most commonly used shelf, each floor load more than 500 kg, called heavy shelf. Heavy shelves have good picking efficiency and can store heavy goods, but the storage density is low. Heavy shelf section
Heavy shelves are widely used in manufacturing, third-party logistics and distribution centers. They are not only suitable for multi-variety and small-batch goods, but also for small-variety and large-batch goods. Such shelves are mostly used in high-level warehouses and super-high-level warehouses (such shelves are mostly used in automated three-dimensional warehouses).

2. Main Characteristics of Heavy Storage Shelf
1. Usually the goods are stored on the shelf after being packed by pallets, storage cages and other units. The load of each unit is generally less than 4000kg, and two units are usually placed in each layer.
2. It is one of the most common and widely used shelves, suitable for most warehouses or products.
3. 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!
4. Storage by mechanical handling equipment.
5. 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).
6. The height of each layer can be freely adjusted by an integer multiple of 75mm.
Heavy-duty (cross-beam type) racks are generally made of cold-rolled profiled steel. The columns are formed by punching diamond holes on the surface of 80 (90) X60 (70) _-shaped steel. The crossbeams are made of 80x50-100x50-120x50-140x50-160x50 embracing welded beams connected with hangers. Trays are generally used instead of laminates to facilitate forklift handling. Layer load 1 ton to 5 tons design, surface electrostatic spraying, waterproof, anti-rust and anti-corrosion ability, high safety factor, plug-in combination, no need for screw and welding, assembly is very convenient, make full use of space area, provide storage capacity.

3. Storage heavy shelf structure
Heavy-duty shelves are assembled by pillars, crossbeams, cross braces, diagonal braces and self-locking bolts, which can effectively prevent the instability of the shelves caused by loosening bolts; the beams are made of special cold-rolled P-shaped closed beams; the structure is simple and reliable, light in weight, strong in bearing capacity and low in cost; the pillars are connected with the pillars with special safety pins designed to ensure that the beams are not subjected to external impact. The laminates are made of strip laminates made in the world, which have the characteristics of strong bearing capacity, wear resistance, simple replacement and low maintenance cost.

4. Installation Method of Heavy Storage Shelf
Firstly, the transverse tension (brace) and the cable-stayed (brace) are installed on the column by screw. Schematic Drawings for Installation of Heavy Storage Shelf
The assembled two pillar pieces (one pillar piece = two pillars + several cross-pulling + several cable-pulling) are erected on the ground. The distance between the two pillars is adjusted to the length of the beam and then the cross-beam is installed. When installing the auxiliary frame, it is also necessary to install the column sheet first, and then adjust the distance between the installed column sheet and one side of the main frame to the length of the cross beam and then install the cross beam. Quantity of cross-stayed: Column length: 1000-1200mm one cable-stayed, two cross-stayed columns: 1300-2200mm two cable-stayed, two or three cross-stayed columns: 2300-3200mm three cable-stayed, two or three cross-stayed columns: 3300-4200mm four cable-stayed, two or three cross-stayed columns: 4300-5200mm five cable-stayed, two or three cross-stayed columns, the number of cable-stayed The following diagram. Generally speaking, the calculation method is one cable-stayed per 600 mm, one cable-stayed at the top and one cable-stayed at the bottom, and one more cable-stayed at the top can be added appropriately.
