The Comprehensive Guide to Used Free-Standing Bridge Cranes in China
Finding the right used free-standing bridge crane can be challenging, especially when navigating the vast market in China. This guide will provide a comprehensive overview of these cranes, exploring their technical features, different types, and factors to consider when making a purchase. Whether you’re sourcing from Tradechina.com, Dejun Crane, BestSuppliers.com, Machinio, or Chinacranemanufacturer.com, this guide will help you make an informed decision.
Understanding Free-Standing Bridge Cranes
Free-standing bridge cranes are self-supporting overhead cranes. Unlike cranes attached to building structures, they stand independently on their own legs or columns. This makes them highly versatile for applications where building modifications are impractical or undesirable. They’re commonly used in workshops, factories, and warehouses for lifting and moving materials. The capacity and design of these cranes vary greatly depending on the intended application.
Technical Features of Free-Standing Bridge Cranes
Several key technical features differentiate free-standing bridge cranes. The choice depends heavily on the specific lifting requirements and the environment. Key features include lifting capacity, span, lifting height, and the type of hoist. Consider the following comparison of typical features:
| Feature | Low Capacity (e.g., 1-2 tons) | Medium Capacity (e.g., 5-10 tons) | High Capacity (e.g., 15+ tons) |
|---|---|---|---|
| Lifting Capacity | 1-2 tons | 5-10 tons | 15 tons and above |
| Span | 5-10 meters | 10-20 meters | 20 meters and above |
| Lifting Height | 3-6 meters | 6-12 meters | 12 meters and above |
| Hoist Type | Electric Chain Hoist | Electric Wire Rope Hoist | Electric Wire Rope Hoist |
| Control System | Manual or Pendant | Pendant, Radio, or Cabin Control | Radio or Cabin Control |
| Construction | Lightweight Steel | Heavy-duty Steel | Heavy-duty Steel, possibly box girder |
The information above is a generalization. Specific specifications will vary based on the manufacturer and the intended use of the crane. Sites like www.dejuncrane.com showcase detailed specifications for their offerings.
Different Types of Free-Standing Bridge Cranes
Several variations exist within the free-standing bridge crane category. These differences mainly involve the crane’s structure and its control mechanisms. The most common types are:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Single Girder | Simpler structure, lighter weight, lower cost | Easier installation, lower maintenance costs | Lower lifting capacity compared to double girder cranes |
| Double Girder | Stronger structure, higher lifting capacity | Can handle heavier loads, greater stability | More complex structure, higher cost, more challenging installation |
| Manual Operation | Operated manually using hand chains or levers | Simpler, lower initial cost | Slower operation, more physically demanding |
| Electric Operation | Operated using electric motors and controls | Faster, more efficient, less physically demanding | Higher initial cost, increased maintenance requirements |
| Workstation Bridge Crane | Designed for specific workstations, often with shorter spans and lower lifting capacities | Optimized for specific tasks, improved efficiency in confined spaces | Less versatile than general-purpose cranes |
| KBK System Cranes | Modular systems using lightweight aluminum components, highly flexible and adaptable | Easy to install and reconfigure, suitable for various applications | Limited capacity |
