FAQ
1. What is a Double Girder Overhead Crane?
A double girder overhead crane is a powerful lifting system designed with two bridge girders running parallel to each other. The hoist and trolley travel along the top of these girders, providing greater lifting height, load capacity, and stability compared to a single girder design. This type of crane is widely used in heavy-duty industrial environments such as steel mills, power plants, and manufacturing workshops.
2. What is the difference between a Double Girder and Single Girder Overhead Crane?
The main difference lies in structure and performance. A double girder overhead crane features two girders, allowing it to handle heavier loads (typically above 10 tons) and achieve higher lifting heights. It also supports more advanced hoisting mechanisms and precise control systems. In contrast, a single girder crane is lighter, more economical, and suitable for medium-duty applications.
3. What are the advantages of using a Double Girder Overhead Crane?
Higher load capacity and stability
Greater hook height due to top-running hoist design
Longer span options for large workshops
Easier integration of maintenance walkways and auxiliary hoists
4. What applications are Double Girder Overhead Cranes ideal for?
They are perfect for heavy manufacturing, steel fabrication, machinery assembly, shipbuilding, and warehouses requiring frequent and precise lifting operations.
5. What factors should I consider when selecting a Double Girder Overhead Crane?
Key considerations include lifting capacity, span length, lifting height, duty class, working environment (temperature, dust, humidity), and control type. Consulting SEVENCRANE’s engineering team ensures a safe and efficient customized solution.
6. Does SEVENCRANE provide installation and after-sales service?
Yes. SEVENCRANE offers complete technical support, installation guidance, operator training, and spare parts supply for all double girder overhead cranes, ensuring long-term reliability and performance.
