Industrial departments and large production factories always need safe, powerful and efficient equipment to move heavy and extra heavy parts. Among the types of material transfer equipment, overhead cranes are known as the main arteries of movement in production halls. The process of designing and manufacturing double bridge overhead crane in Isfahan is of double importance due to the concentration of mother industries such as steel, iron smelting, stone cutting and machine workshops in this province. Due to having two parallel bridges in their structure, these types of cranes provide the ability to move very heavy loads in wide spans with very high stability. Choosing a reliable and experienced manufacturer in this field will guarantee the safety of personnel and increase the efficiency of production lines.
What is a bridge overhead crane and what are its uses?
Double-bridge overhead crane, which is also called double-bridge crane in technical terms, consists of two parallel metal beams or box structures, and the carriage containing the lifting winch moves on the rails installed on these two bridges. This structural design allows the machine to drive the load to a higher height, as the lifting hook can rise up between the two bridges. The process of making double bridge overhead cranes in Isfahan is mainly defined for industries that deal with load capacities of more than 5 tons and spans of more than 15 meters. This structure creates great rigidity and resistance to bending and twisting against the dynamic forces resulting from the movement of the load.
The applications of this equipment are very wide and include from foundry and metal melting halls to power plants, automotive industries and large iron warehouses. In Isfahan province, which is known as the industrial capital of Iran, the need for this powerful tool is felt in all industrial towns. By understanding these needs, Poulad Dhanir Raika designs and implements all types of bridge cranes according to the work class (Group Classification) required by the employer, from light to super heavy and permanent classes.
The key advantages of making double bridge overhead cranes in Isfahan
The design of two bridges brings many technical and economic advantages for industrial units, the most important of which is maximizing the useful lifting height. In halls where ceiling height is limited, the construction of a double bridge overhead crane in Isfahan allows the dead space between the two bridges to be used and the hook to go up as high as possible. In addition, maintenance and repair corridors can be easily installed on one of the bridges, which makes it very safe and easy for technicians to access motor gearboxes, carriages and electrical equipment.
The stages of engineering and construction of double bridge overhead crane in Isfahan
The production process of a quality industrial crane starts from the detailed engineering steps and ends with the final installation and commissioning. The first step is to accurately measure the dimensions of the hall, including the useful opening, the height of the columns, the distance to the ceiling, and the length of the longitudinal movement path. After collecting the initial information, structural calculations are performed based on valid standards such as DIN, FEM and CMAA. At this stage, the thickness of the sheets, the dimensions of the boxes and internal stiffeners are determined to prevent local buckling of the sheets.
After the approval of the shop drawings in Raika's Polad Tighar engineering unit, the sheet cutting operation begins with advanced machines such as CNC powder coating and box assembly. Welds are subjected to strict quality control and non-destructive testing (NDT) such as ultrasonic and radiographic tests to ensure the integrity of the joints. Finally, after surface preparation and sandblasting, the structure is covered with special industrial epoxy paints to be highly resistant to the environmental conditions of the workshops.
Factors affecting the construction price of double bridge overhead crane in Isfahan
The final price of a ceiling crane is influenced by several factors, which must be checked carefully before purchasing. The permissible load capacity (SWL) and the length of the hall opening are the first and most influential factors on the weight of the metal structure and, as a result, the final cost. In addition to the weight of the hardware used, the type and brand of the lifting equipment and the driving force (engines and gearboxes) play a decisive role in the price of making a double bridge overhead crane in Isfahan. The use of reliable European brands such as Demag, Konecranes or other high-quality brands increases the initial costs but guarantees the stability of the system.
Another important factor is the working class of the device; A crane that works in a power plant several times a year has a different design and equipment than a crane that is active in three shifts and continuously in a steel factory. Working environmental conditions such as high temperature, presence of dense dust or humidity also affect the choice of the type of insulation of motors and electrical equipment. By providing free expert advice to employers, Raika's driving force helps them to choose the most optimal technical configuration according to their budget and real needs without paying additional costs.
National and international standards in the construction of lifting equipment for two bridges
Safety is the first word in overhead cranes, and compliance with design standards is the main foundation of this safety. The FEM standard (European Material Handling Association) and the CMAA standard (Crane Manufacturers Association of America) are the two main references that specify the criteria for structural fatigue calculations, the selection of motors and lifting mechanisms. In our country, it is mandatory to comply with the national standards of Iran and obtain work health approval (technical orthopedics and work inspection) to set up these devices.
Raika's Polad Timar engineering team performs all its mechanical and electrical calculation steps according to the latest editions of international standards. In the process of making a double bridge overhead crane in Isfahan by this company, all critical parts such as hooks, pulleys, drums and brakes have a very high safety factor so that there is no danger to the structure and the workshop personnel in sudden loading conditions. After the installation is completed, static tests (usually 125% of nominal capacity) and dynamic tests (110% of nominal capacity) are performed with the presence of third-party inspectors and a health certificate is issued.
Why is Raika's driving force the best choice for Isfahan industries?
Choosing a committed manufacturer that has the ability to provide long-term support is the main concern of factory managers. As a registered and reliable brand, Poulad Trahim Raika Company, relying on its equipped workshop in the industrial hub of the country, offers the process of making bridge overhead cranes in Isfahan with the highest possible quality. The use of modern technologies in the welding of the structure, the use of modern power supply line systems (closed busbar or serial) and the use of electrical panels equipped with remote control drives (inverters) to eliminate start and stop shocks are among the features of this company's products.
The commitment of Polad Dhanir Raika does not end only with the delivery of the device; Fast after-sales service, supply of original spare parts, periodical inspections and providing a valid company warranty are among the commitments that this collection offers to its customers. Due to the direct presence of this company in Isfahan, the time to respond to repair and service requests is minimized and the long-term stoppage of production lines is avoided.
