Drag Chains for Double Girder Overhead Cranes
Enhancing Efficiency in Double Girder Overhead Cranes
Double girder overhead cranes are particularly flexible crane types that ensure the lifting and transport of high loads, especially in warehouses or production halls. Due to the wide range of applications of the systems, a tailor-made energy supply solution is required depending on the application. Our energy chains, guide troughs and cables are also designed for quick retrofitting, quiet movement and the smallest bending radii.

The Challenges of Cable Festoon Systems
Cable festoon systems have been a staple in crane operations for many years, but as demands for faster installation, increased flexibility, and improved technology have grown, the drawbacks of cable festoon systems have become apparent.

Double girder vs single girder crane
Single girder cranes have one bridge beam, making them cost-effective, lighter, and simpler to install and maintain. Double girder cranes, with two bridge beams, offer higher load capacities, greater hook height, and the ability to incorporate more features like walkways and cabs. They are suitable for heavy-duty applications and environments requiring higher lifting and longer spans
- Cost-Effective: Single girder cranes use fewer materials and have a simpler design, reducing costs.
- Efficient Use of Space: Ideal for areas with limited vertical space, offering superior hook approaches.
- Easy Installation and Maintenance: Simpler structure makes them easier to install, service, and maintain.
- Lower Building Load: Reduced deadweight means less structural support is needed
- Limited Capacity: Typically up to 15-20 tons, not suitable for very heavy loads.
- Lower Hook Height: The hoist under the girder limits lifting height.
- Fewer Features: Adding components like walkways or cabs can be challenging and costly
Choose a single girder crane if you need a cost-effective solution for light to moderate loads, have limited vertical space, and require a crane that is easier to install and maintain. They are suitable for workshops, warehouses, and smaller manufacturing facilities
- Single girder cranes typically handle up to 15-20 tons, while double girder cranes can lift up to 500 tons, making them suitable for more demanding industrial tasks
- Higher Load Capacity: Can lift heavier loads, often up to 500 tons.
- Greater Hook Height: The hoist can be placed between or on top of the girders, providing more lifting height.
- Versatility: Can accommodate additional features and are suitable for both indoor and outdoor use.
- Stability and Safety: Better for frequent heavy lifting and offers enhanced stability
- Higher Costs: More materials and complex design increase initial costs and setup.
- Space Requirements: Requires more overhead space and additional structural support.
- Complex Maintenance: More sophisticated components can demand specialized maintenance
Opt for a double girder crane when you need to lift heavy loads, require greater hook height, or need to incorporate additional features like walkways. They are ideal for heavy-duty applications such as mining, steel production, and large manufacturing plants
Double girder cranes are more expensive due to higher material and installation costs but offer better performance for heavy-duty applications. Single girder cranes are cost-effective for lighter loads and simpler maintenance, making them ideal for smaller operations
System Comparison: e-chain systems instead of festooning
Provide guidance for cables and energy chains while keeping them protected and safe in wind and fluctuating temperatures, minimizing downtime.
System Comparison: e-chain systems instead of busbar systems
Deliver data, energy, fluids and air safely in a single energy chain system. For narrow compact spaces and fast lane movement.
