What Is a Double Girder Overhead Crane?

If your facility deals with lifting heavy materials, chances are you’ve come across the term double girder overhead crane. But what exactly is it, and how does it differ from other types of industrial cranes?

Let’s break down what a double girder crane is, where it’s used, and why so many factories and warehouses choose it for heavy-duty operations.

Understanding the Double Girder Overhead Crane

A double girder overhead crane is a type of bridge crane designed with two horizontal beams (girders) that support a hoist. Unlike single girder cranes—where the hoist typically hangs underneath—the hoist on a double girder runs along a trolley that travels on top of the girders. This allows for:

• Higher lifting heights
• Greater load capacities
• Longer spans and more robust structure

This type of crane is commonly found in manufacturing plants, steel yards, warehouses, and workshops where lifting 20+ ton loads is part of the daily operation. You can see a detailed example of one from this double girder EOT crane model, designed specifically for precision and heavy-duty applications.

Main Types of Double Girder Cranes

“EOT” stands for Electric Overhead Traveling. These cranes are installed inside buildings and run on tracks mounted on beams. A double girder EOT crane offers smooth movement, better control, and is perfect for production lines, assembly plants, and fabrication workshops.

When overhead support structures aren’t available or practical—such as in shipyards, construction zones, or rail yards—a double girder gantry crane is the better choice. It operates on rails laid on the ground and can carry massive loads outdoors, often in harsh environments.

Why Choose a Double Girder Crane?

There are several advantages to choosing a double girder system over a single girder or portable crane setup:

• Heavy Lifting: These cranes can handle very high capacities, sometimes up to 100 tons.
• Long Span Capabilities: Ideal for wide factory spaces.
• Maximum Hook Height: Because the hoist rides on top of the girders, it allows for greater lifting height.
• Customizable: Can be equipped with walkways, maintenance platforms, and extra features to match your facility’s needs.

If your operations demand reliable, heavy-duty lifting with minimal downtime, a double girder crane is a solid investment.

Final Thoughts

A double girder overhead crane is an essential tool for industries that need to move large, heavy materials safely and efficiently. Whether you’re operating indoors with a precision EOT system or outdoors with a rugged gantry crane, the double girder design offers durability, performance, and long-term value.
