The Comprehensive Guide to Double Beam Overhead Cranes in China
Double beam overhead cranes are essential material handling equipment widely used across various industries in China. These robust cranes offer high lifting capacities and are crucial for efficient operations in manufacturing, warehousing, and logistics. Understanding their technical features and the differences between various types is vital for selecting the right crane for specific needs. Numerous Chinese manufacturers, such as those found on websites like www.chinacranemanufacturer.com and www.sinokocrane.com, offer a wide range of options.
Understanding the Mechanics of Double Beam Overhead Cranes
Double beam overhead cranes, also known as double girder overhead cranes, consist of two main girders running parallel to each other. These girders support a bridge structure that travels along a runway system. A trolley, equipped with a hoist mechanism, moves across the bridge, enabling the crane to lift and move loads across the entire span. The control system, which can be a pendant, remote control, or driver’s cabin, manages the crane’s movements. The entire system is designed for heavy-duty lifting operations, as seen in the specifications from companies like www.ygcrane.com.
Technical Features Comparison:
The following table compares key technical features of double beam overhead cranes:
| Feature | Description |
|---|---|
| Lifting Capacity | Ranges from 5 tons to 500 tons or even higher, depending on the crane’s design. |
| Span | The distance between the crane’s runway rails, typically ranging from 5m to 40m. |
| Working Class | Indicates the crane’s duty cycle and determines its structural strength (A4-A8). |
| Lifting Speed | Varies depending on the hoist’s motor and gearing. |
| Travel Speed | Varies depending on the crane and trolley’s motor and gearing. |
| Control System | Can be pendant, remote, or cabin control, offering flexibility in operation. |
| Material | Typically constructed from high-strength steel, such as Q235 or Q345 steel plates. |
| Safety Features | Include overload protection, limit switches, emergency stops, and more. |
Many manufacturers, including those listed on www.eurocranegroup.com, customize these features based on specific client needs.
Types of Double Beam Overhead Cranes:
Different types of double beam overhead cranes cater to specific applications. The following table highlights their key differences:

FAQs:
1. What are the main advantages of a double beam overhead crane over a single beam crane?
Double beam cranes offer significantly higher lifting capacities and are more robust for heavier loads. They also provide better stability and longer lifespans.
2. How is the working class of a double beam overhead crane determined?
The working class (A4-A8) is determined by the crane’s duty cycle and frequency of operation. Higher classes indicate more frequent and heavier use.
3. What safety features should I expect in a modern double beam overhead crane?
Modern cranes typically include overload protection, limit switches, emergency stops, anti-collision devices, and potentially more sophisticated safety systems.
4. What factors should I consider when selecting a double beam overhead crane?
Consider lifting capacity, span, working class, lifting and travel speeds, control system, and environmental conditions. Also, consider the manufacturer’s reputation and after-sales service.
5. What is the typical lifespan of a well-maintained double beam overhead crane?
With proper maintenance, a double beam overhead crane can last for 30-50 years or even longer. Regular inspections and timely repairs are crucial for extending its lifespan.
