How to Choose the Right Double Girder Overhead Crane
Choosing the right double girder overhead crane for your specific needs involves several key considerations. Here’s a comprehensive guide to help you make an informed decision:
Understand Your Application Requirements
- Load Capacity: Determine the maximum weight the crane needs to lift. Double girder top running cranes are ideal for handling heavy loads, often ranging from 20 to 500 tons or more. Ensure the crane’s capacity exceeds the maximum load to provide a safety margin.
- Span: Measure the distance between the crane’s runway beams. This span will determine the crane’s coverage area. Double girder bridge cranes can handle wider spans compared to single girder overhead cranes, making them suitable for larger workspaces.
- Lifting Height: Consider the height from the ground to the highest point the crane needs to lift. This includes the distance between the crane’s hook and the load’s lifting point.
- Operating Environment: Evaluate the environmental conditions where the crane will be used. For example, if the crane operates in a high-temperature environment, a high humidity area, or a corrosive environment, you may need specialized materials or protective coatings.
Consider the Crane’s Duty Cycle
- Duty Cycle: This refers to how frequently the crane will be used. Cranes are categorized based on their duty cycles, such as light duty overhead crane, medium duty overhead crane, or heavy duty overhead crane. Choose a crane with a duty cycle rating that matches your operational demands.
Evaluate Control Options
- Pendant Control: Offers a simple and cost-effective way to control the crane from the ground.
- Radio Remote Control: Provides greater flexibility and allows the operator to control the crane from a distance, enhancing safety and convenience.
- Cab Control: Ideal for larger overhead cranes or complex operations, providing a comprehensive control system with visibility and operator comfort.
Assess Safety Features
- Anti-Sway Mechanism: Helps to stabilize the load and reduce swaying during lifting and travel, which is crucial for precision and safety.
- Overload Protection: Prevents the crane from lifting loads that exceed its capacity, protecting both the crane and the load.
- Emergency Stop: An essential feature for halting crane operations immediately in case of an emergency.
Consider Customization
- Special Attachments: Consider adding attachments such as grabs, magnets, or spreader beams for handling specific types of loads.
- Special Features: Depending on your application, you may need custom features such as custom spans, or unique controls. Discuss your requirements with the crane manufacturer to explore customization options.
When buying a double girder overhead crane, always consult with experienced crane manufacturers and suppliers to ensure you make an informed decision and invest in a crane that meets your needs both now and in the future.

Single Girder vs Double Girder Overhead Crane
When evaluating your options for an overhead crane, understanding the key differences in the single girder vs double girder crane debate is essential. Both types have their advantages and are suited to different applications.


Best for lighter to medium-duty tasks. If your application involves lighter loads or smaller span requirements, a single girder bridge crane might be the cost-effective solution.
Load Capacity and Weight
Necessary for heavy-duty tasks, such as lifting large equipment or heavy components. The double girder design provides superior load capacity and stability.
Limited in terms of span and lifting height. Suitable for applications with shorter spans and lower height requirements.
Span and Lifting Height
Ideal for situations where larger spans and greater lifting heights are needed. The design allows for a greater range of motion and versatility.
Generally more affordable and quicker to install. The simpler design results in lower overall costs, both in terms of initial investment and maintenance.
Cost and Installation
Higher initial investment due to the more complex design. However, they provide a longer-term investment by offering greater capacity and durability, which can be crucial for heavy-duty applications.
Limited in terms of span and lifting height. Suitable for applications with shorter spans and lower height requirements.
Maintenance and Durability
Ideal for situations where larger spans and greater lifting heights are needed. The design allows for a greater range of motion and versatility.
In conclusion, the choice between a double girder vs single girder crane depends largely on your specific operational requirements. While single girder cranes are well-suited for lighter, less complex tasks, double girder cranes offer the strength and flexibility needed for more demanding applications. By understanding the distinctions and considering your operational needs, you can make an informed decision on the right crane type for your business.
