Box beam double girder gantry crane, with double beam hoist crab /open winch trolley for heavy duty load handling, 5 ton - 550 ton. Gantry crane for sale. The box type double-girder gantry crane is a heavy duty gantry crane with two girders that is commonly used for general purposes. Double girder gantry cranes are heavy-duty cranes that are used both indoors and outdoors in situations where overhead crane runways are impractical. The capacity of the double girder gantry crane ranges from 5 to 500 tons. The gantry crane's working classes are A5 and A6.


Because the lifting capacity of a box girder gantry crane can reach hundreds of tons, it is also classified as a heavy duty gantry crane. In comparison to the single girder gantry crane, the gantry crane has a higher carrying capacity, a larger span, and better stability; therefore, it will be much more expensive.The double girder gantry crane are usually adopted for large and heavy loads handling in outdoor workplaces such as ports, shipyards, warehouses, and construction sites.
