Cantilever rack is an important type of racking, also named industrial pipe rack. Arm cantilever racks are suitable for storing long materials, ring-shaped materials, plates, pipes and irregular goods. The cantilever rack system can be single-sided or double-sided. Cantilever storage racking has the characteristics of stable structure, good load capacity and high space utilization. Cantilever pipe rack column mostly adopts H-beam or cold-rolled steel, arm adopts square tube, cold-rolled steel or H-beam, plug-in or bolt connection between arm and column, bolt connection between base and column, base adopts cold-rolled steel or H-beam.
Cantilever storage racking is composed by installing arm on the column, and the arm can be fixed or mobile. Pipe and plate storage are used more often. According to the load-bearing capacity, it can be divided into three types: light-weight, medium-weight and heavy-weight; according to the structure form, it can be divided into single-sided cantilever racks and double-sided cantilever racks.
Use of heavy duty cantilever racks
Cantilever shelf is suitable for storing long materials, ring-shaped materials, plates, pipes and irregular goods. Pipe shelf column mostly adopts H-beam or cold-rolled steel, cantilever arm adopts square tube, cold-rolled steel or H-beam, cantilever arm and column adopt plug-in or bolt connection type, base and column adopt bolt connection type, base adopts cold-rolled steel or H-beam. Cargo access is carried out by forklift, traveling crane or manually. The height of the rack is usually within 2.5 meters (up to 6 meters if the goods are accessed by forklift), the length of the arm is within 1.5 meters, and the load per arm is usually within 1000 KG. These racks are mostly used in the machinery manufacturing industry and building materials supermarkets. With the addition of racks, it is especially suitable for warehouses with small space and low height, convenient management, wide view, and higher utilization rate compared with ordinary racks; according to the load-bearing capacity, it can be divided into three types: light-weight, medium-weight and heavy-weight.
For storing bulky, scattered or other special products, pipe rack system is the ideal solution. Adjustable cantilever storage racking is available in single-arm and double-arm versions and is highly efficient for storing wood, pipes, long items and other similar products. Arm cantilever racking is a special type of racking for long products, which is made by installing external arms on traditional racking columns.
Structural advantages of cantilever racking
The cantilever racking system can be single-sided or double-sided, and pipe shelving has a stable structure, good load capacity and high space utilization. Cargo access is carried out by forklift, crane or manually.
The height of the steel pipe storage rack is usually within 2.0 meters (up to 6 meters if the goods are accessed by forklift), the length of the arm is within 1.5 meters, and the load per arm is usually within 800 KG.
Application of cantilever pipe racking
The pipe storage rack is mostly used in the machinery manufacturing industry and building materials supermarkets. With the addition of racks, it is especially suitable for warehouses with small space and low height, easy to manage, wide view and higher utilization rate than ordinary racks.
The production process of racking
The base of heavy duty cantilever racks can be made of H-beam or special profiles. The selection of H-beam is based on the requirements of load-bearing and the corresponding choice of national standard steel. The upper side of the h-beam is opened with the column bolt connection eye to facilitate the connection with the column. The bottom side is welded to the bottom plate, and the expansion bolt eye is opened above the bottom plate to connect the rack to the ground with expansion bolts. To fix the racks.
Heavy duty cantilever racks use special profiles for the base, and two pieces of c-beams are welded together back to back with connecting steel plates, the width of which is the width of the column. The width of the connecting steel plate is the width of the column. After the welding of the two pieces of c-beams is completed, the connecting bolt eye is opened at the position of the connecting column to facilitate the connection with the column. Side welding connection base plate, easy to expand the bolt and ground connection.
The cantilever pipe rack column is welded together by two pieces of c-beam. c-beam is made of q235 high quality strip steel, rolled into c-beam by rolling mill line, and then punched out arm connection control on automatic punching machine with 140mm hole spacing. a connecting steel plate will be welded under the column if it is connected with H-beam. If the connection with a special profile is adopted, the bolt connection hole will be opened at the connection part under the column.
Production material of cantilever storage racks
Cantilever storage racks are generally made of two types of materials
1、Made of square tube: cantilever storage racks are made according to the corresponding arm layer load requirements, first select the square tube that meets the layer load requirements, cut it into the required size, weld the anti-slip guard at one end, and weld the connection u-type column connection at the other end.
2、Made of c-beam: cantilever storage racks are made according to the corresponding arm layer load requirements, and the specifications of c-beam are selected first, and then two pieces of c-beam are butt-welded after selection, and the anti-slip guard is welded at one end after welding, and the u-shaped column connector is welded at the other end.
Cantilever pipe rack column piece and column piece connected by connecting rod, connecting rod is generally made of rectangular tube. In order to increase safety and stability, a flat iron back pull is added to the connecting rod to tightly fix the column piece.
All cantilevered racking components are semi-finished products after production, will be sprayed by the last process. In the spraying before the shot blasting machine shot blasting oil removal, rust removal, and then spraying. After completion, we will pack and ship.
Structural characteristics of rack cantilever
1、Cantilever type racks have single arm and double arms, which are efficient for storing wood, pipes, long objects and other similar products. Car cantilever racking can be made up of a single column piece unit with a cantilever arm through horizontal ties, diagonal ties and other continuous compositions of multiple unit systems.
2、Pipe storage cantilever racking is a proven storage system in terms of quality, safety and management. The column piece consists of a column and base. The column is made of two pieces of specially designed C section steel butt-welded together, and this structure makes full use of the material’s load-resisting capacity and has the characteristics of large load bearing and low cost.
3、The column is prefabricated with double rows of holes, the pitch of the holes is 100mm, and the arm is connected to the column through the plate pin, which can be adjusted up and down with 100mm as the pitch.
Features of the warehouse cantilever rack
1、Only suitable for long strip or long volume goods storage.
2、It is necessary to cooperate with the handling equipment with wide fork spacing, such as side forklift with large fork spacing.
3、The height of the rack is limited, generally below 6m.
4、Low space utilization, about 35%-50%.
5、Storage type: long strips and long rolls.
