A Type Double Girder Gantry Crane

What is this?

The A type double girder gantry crane is a heavy-duty gantry crane featuring an A-frame leg design with a double main beam structure. The A-shaped legs provide exceptional stability and weight distribution, making this crane ideal for outdoor stockyards and heavy industrial applications. Through the coordination of an electric wire rope trolley with main and auxiliary hooks, combined with crane traveling mechanisms, it achieves precise lifting and handling of heavy materials, large equipment, steel coils, containers, prefabricated components, and more. If you need a stable, high-capacity gantry crane for outdoor heavy lifting with long spans and high wind resistance, this product is designed for you.

Why choose an A type double girder gantry crane over a U type or L type gantry crane?

Compared to U type or L type gantry cranes, the A type double girder solution offers four core advantages:

First, superior stability – the A-frame leg design provides a wider base and lower center of gravity, reducing sway and improving stability during heavy lifts, especially in outdoor windy conditions.

Second, higher wind resistance – the inclined A-frame legs distribute wind loads more effectively, allowing safe operation in higher wind speeds compared to straight-leg designs.

Third, better load distribution – the A-frame design transfers heavy loads evenly to the ground rails, reducing wheel load concentration and extending rail and wheel life.

Fourth, ideal for long spans – the rigid A-frame structure maintains stability over spans exceeding 40 meters, covering wide stockyards and storage areas.

Take on heavy outdoor lifting with superior stability and wind resistance.

What can we do for you?

We understand that every customer has different capacity requirements, different spans, and different working environments. Therefore, we offer flexible customization options: lifting capacity from 5 tons to 100 tons (up to 500t available); span from 18 meters to 50 meters; main/auxiliary hook ratios such as 20/5t, 50/10t, 100/20t; A-frame leg angles customizable for different wind load requirements; single or double cantilever; control options of cabin, remote radio, or pendant; VVVF speed control for smooth start/stop. Whether your site is an outdoor steel stockyard, a port terminal, or a heavy equipment assembly yard, we can match the most suitable span and lifting height.

Unsure? Don't know?

Not sure whether an A type or U type leg design suits your site conditions? Don't know what span covers your stockyard? No problem. Just tell us: your maximum lifting capacity, your stockyard span or width, your local wind speed conditions, and whether you need cantilevers. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.

1. Steel Stockyards

The A type gantry crane handles steel coils, plates, pipes, H-beams, and structural sections. The stable A-frame design prevents load sway when lifting long steel members. Heavy-duty wheels withstand continuous operation on outdoor rail systems. The double girder structure provides the rigidity needed for precise placement of steel products onto trucks or storage racks.

2. Port Terminals and Container Yards

The crane lifts containers, heavy machinery, and bulk cargo at secondary wharves and container yards. The A-frame legs provide excellent stability during ship-to-shore operations. Wide span covers multiple container rows. High wind resistance allows continued operation during coastal breezes.

3. Precast Concrete Factories

Moving concrete beams, wall panels, pipes, and heavy molds from curing beds to storage yards. The stable A-frame design prevents swinging of long concrete members. Precise control allows careful placement of finished products onto transport trailers.

4. Heavy Equipment Assembly Yards

Relocating large components such as transformer bodies, wind turbine sections, mining equipment parts, and generator stators. The A-frame design provides the stability needed for precision positioning of high-value components. Main and auxiliary hooks allow handling of unbalanced loads.

5. Railway Freight Stations Loading and unloading heavy goods like rail tracks, wheelsets, locomotive components, and transformers from rail cars to trucks or storage. The long span covers multiple rail tracks. Stable operation ensures safe handling of valuable railway equipment. 6. Outdoor Storage Yards Stacking and retrieving heavy materials, pipes, construction materials, and industrial equipment in outdoor storage areas. The A-frame design withstands weather exposure. Corrosion-resistant coatings protect against rain and humidity.
