Overview Double Girder Gantry Crane

What is a Double Girder Gantry Crane?

Double Girder Gantry Cranes are heavy-duty lifting systems designed with two parallel beams supported by rigid steel legs, allowing the trolley to travel on rails mounted on top of the beams. This advanced structural configuration enables higher lifting capacities, long-span portal configurations and increased lifting heights.

Built from high-strength structural steel, double girder gantry cranes deliver maximum stability, precise load positioning, smooth bridge travel and excellent hook approach. These cranes are purpose-built for heavy-duty material handling in outdoor applications such as steel yards, ports, prefabrication plants, shipyards and large industrial facilities.

FAQ

Double Girder Gantry Crane FAQ

Common questions about Wimac double girder gantry cranes — capacity, duty class, span ranges and typical applications.

What is a double girder gantry crane?
A double girder gantry crane is a heavy-duty portal crane built with two parallel main girders supported by free-standing legs. The hoist trolley runs on rails mounted on top of the girders, which delivers higher lifting capacity, greater hook height and longer spans than a single girder gantry — the preferred configuration for heavy outdoor handling.
What is the maximum lifting capacity of a double girder gantry crane?
Wimac double girder gantry cranes are engineered from 5 t up to 320 t and beyond on custom projects. Above ~80 t the double girder configuration is essentially mandatory due to bridge bending and deflection at typical gantry spans.
When should I choose double girder over single girder gantry?
Choose a double girder gantry crane when the project requires capacity above ~20 t, span above ~25 m, maximum hook height, a higher FEM duty class (M5 / M6 / M7), or service add-ons like cantilever arms, walkways, cabin operation or auxiliary hoists. For lighter, low-cycle outdoor lifting a single girder gantry is more economical.
What FEM / ISO duty classes do double girder gantries meet?
Wimac double girder gantry cranes are designed and verified in the FEM 2m to 4m / ISO M5 to M8 duty class range, covering medium-, heavy- and very heavy-duty continuous service. Full FEM / ISO reference is in our general information & selection guide.
What span and lifting height ranges are available?
Standard Wimac double girder gantry cranes cover 10 m to 60 m span and 6 m to 30 m lifting height, with VFD-controlled motions on hoist, cross-travel and long-travel. Cantilever extensions and higher capacities are available on engineered projects.
Where are double girder gantry cranes typically used?
Typical applications include steel stockyards, port and container terminals, prefabrication yards, shipyard outfitting, heavy concrete and precast plants, rail yards and any outdoor or semi-outdoor site requiring continuous heavy-duty material handling. Hazardous-area variants are available as ATEX / IECEx explosion-proof gantry cranes.
