Double Girder Gantry Crane

Double girder gantry crane is capable of handling large and heavy loads in outdoor workplaces, such as port, shipyards, warehouse and construction site.

The lifting capacity of double girder crane can reach hundreds of tons, therefore it is also a kind of heavy duty gantry crane. The gantry crane has stronger carrying capacity, larger span and better stability in contrast with the single girder gantry crane, thus it will cost much more than the single girder type.

According to the main beam structure, the gantry crane falls in two forms including box type and truss type, and the former is more often adopted. We also supply non-standard custom designs to meet unique requirements of customers.

Q&A

What Is Double Girder Gantry Crane?

Double girder gantry crane is a bridge type crane in which the bridge frame is supported on the ground track through the legs at both ends.

It is mainly composed of the gantry frame (main beams, end beam, legs, lower beam, trolley running track and cab.), hoist trolley, crane running mechanism and electric control system.

The hoisting trolley is equipped with a hoisting mechanism and a trolley running mechanism that runs laterally along the trolley track on the main girder of the bridge.

The main girder can extend out of the legs to one or both sides to form a cantilever to increase the lifting coverage of the crane, but the length of the cantilever is generally less than or equal to 1/3 span length.

What Is A Double Girder Gantry Crane Used For?

Double girder gantry crane is extensively used in mechanical processing, metallurgy, chemical industry, power plant, shipbuilding, port terminal, freight yards, etc.

According to different fetching devices, the double-beam crane can be used in different workplaces:

Hook gantry cranes use hooks as fetching devices, and are widely used in machining, warehouses and cargo yards.

Grab gantry cranes use grab buckets as fetching devices and are widely used in warehouses, stockyards and open-air cargo yards for loading, unloading and lifting bulk cargo.

Electromagnetic gantry crane uses a detachable electromagnetic chuck as a fetching device. It is widely used in metallurgy and machining workshops to assemble and transport magnetically permeable black products and materials, such as steel ingots, section steel, pig iron blocks, scrap iron and scrap steel.
