L Single girder heavy-duty gantry crane

What is this?

The single girder heavy-duty gantry crane is a gantry crane featuring a reinforced single main beam structure. It uses an electric hoist or electric trolley to lift and lower loads and move left and right, with legs running on ground rails, achieving precise lifting and handling of heavy materials, large equipment, steel structures, prefabricated components, and more. If you need lifting capacity from 10 tons to 50 tons but have a limited budget or constrained foundation conditions that cannot accommodate a double girder gantry crane, this product is designed for you.

Why choose a single girder heavy-duty gantry crane over a double girder gantry crane?

Compared to double girder gantry cranes, the single girder heavy-duty solution offers four core advantages:

First, lower investment cost – reinforced single girder structure reduces overall self-weight by 15%-25% compared to double girders, significantly lowering costs, suitable for budget-limited projects.

Second, shorter installation time – simpler structure with lower rail foundation requirements, reducing installation and commissioning time by about 30%.

Thid, greater headroom – the single girder occupies less space, providing higher effective lifting height under the same building clearance.

Fourth, lower maintenance cost – simple structure with fewer failure points, resulting in less daily inspection and maintenance workload.

Get close to double girder load capacity with a more economical investment.

What can we do for you?

We understand that every customer has different capacity requirements, different spans, and different site conditions. Therefore, we offer flexible customization options: lifting capacity from 10 tons to 50 tons; span from 15 meters to 35 meters; control options of cabin, remote radio, or pendant; VVVF speed control for smooth start/stop; leg types of A-frame or L-frame. Whether your site is an outdoor stockyard or an indoor workshop, we can match the most suitable span and lifting height.

[1] High Load Capacity in Single Girder – Reinforced design allows heavy lifting (10‑50t) with lower cost than double girder.

[2] Cost-Effective for Medium Spans – Ideal for spans up to 30m where double girder would be over‑specified.

[3] Durable and Reliable – Heavy‑duty wheels, sealed bearings, and robust structure for tough environments.

[4] Easier Maintenance – Single beam provides good access to hoist and trolley components.

[5] Flexible Power Options – Available with pendant, radio remote, or cabin control.
