Drag Chains for Double Girder Overhead Cranes

• 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.
