1. Brief Introduction of Cantilever Storage Shelf

Cantilever storage rack is one of many types of storage rack. It adopts the structure of column and cantilever arm, which is suitable for storage of long material, plate, ring material and irregular goods.

2. Cantilever Storage Shelf Structure

Cantilever rack: special profile column with high strength cantilever is used to store long material, ring material, sheet material and irregular material. The forward cantilever can be single-sided or double-sided. It has the characteristics of light structure and good load-carrying capacity. The load-bearing capacity of the single arm can reach 500 kg. The specially reinforced column structure can withstand the pressure of 2000-3000kg. Designed back pull to increase overall stability of shelf, easy installation, complete accessories. Composite structure, special profile column, design back pull to increase stability, with high strength cantilever (arm can be single or double sides), with lightweight structure, good load capacity, high space utilization rate; with shelf, especially suitable for small space, low height warehouse, convenient management, wide field of vision, compared with pallet rack, the utilization rate is higher; according to the carrying capacity can be divided into light type. Cantilever rack, medium-sized cantilever rack and heavy-duty cantilever rack are suitable for storage of long materials, plates, ring materials and irregular goods.

3. Production Technology of Cantilever Storage Shelf

The base of cantilever rack can be made of H-section steel or special profile. H-section steel is selected according to the requirement of bearing capacity, and the national standard steel is selected accordingly. The upper edge of H-section steel is provided with bolt connecting eye for the column, which is convenient for connecting with the column. The bottom is welded to connect the bottom plate, and the top of the bottom plate is opened with expansion bolts, so that the shelf can be easily connected to the ground with expansion bolts. Fixed shelves.
The cantilever shelf uses special profiles as its base, and welds two pieces of C-shaped steel back to back with connecting steel plates. The width of connecting steel plates is the width of the column. After the welding of two pieces of C-section steel is completed, bolt holes are opened at the connecting posts to facilitate the connection with the posts. Edge welding is used to connect the bottom plate to facilitate the connection between expansion bolts and the ground.
Cantilever rack columns are butt welded together with two C-section steel sheets. C-section steel takes Q235 high-quality strip as raw material. After rolling into C-section steel by rolling mill line, the cantilever connection control is punched out on the automatic punch, and the hole spacing is 140 mm. A connecting steel plate will be welded under the column by connecting with H-section steel. If the connection with special profiles is adopted, bolt connection holes will be opened at the connecting part below the column.

4. Manufacture of Cantilever Storage Shelf Material

Cantilever shelves are generally made of two materials:
1. Adopt square control: According to the corresponding cantilever layer load requirements, the cantilever shelf first chooses the square tube that meets the layer load requirements and cuts it into the required size. It is made by welding anti-skid guard plate at one end and U-shaped column connector at the other end.
2. Made of C-section steel: According to the corresponding cantilever overlay requirements, the cantilever shelf first chooses the specifications of C-section steel, and then welds two pieces of C-section steel. After welding, the anti-skid guard plate is welded at one end and the U-shaped column connector is welded at the other end.
Connecting rod is used between cantilever shelf column and column. Connecting rod is usually made of rectangular tube. In order to increase safety and stability, a special puller is needed to tightly fix the column sheet by adding a flat iron back pull to the connecting rod.
All cantilever rack parts are semi-finished products after production, and will be sprayed through the last process. Before spraying, oil and rust are removed by shot blasting machine before spraying. Packing and delivery after completion.
