What is a double girder gantry crane ? Double girder gantry crane is the most frequently used structure design, with the features of strong bearing capacity, large span, good overall stability, and coming in many varieties, but the self-weight of the double girder gantry crane is larger and their processing cost is higher compared with single-girder double girder gantry crane . Double girder gantry cranes can be designed into box girder and truss girder designs, but usually in box shape girder designs.

Double girder gantry cranes

A double girder gantry crane is mainly composed of the crab travelling, the trolley travelling, electrical, gantry and other components. It can use cable reel power supply, with diesel generator power supply or bare copper slip line power supply.

Main types and specifications of double girder gantry cranes

Double girder gantry crane carrying capacity is strong and the span can be very large. The overall stability is good. Compared with single girder gantry crane, the overall rigidity of the double form is stronger. Because the gantry crane has two girders, the entire structure has stronger stability. In different condition, our technicians design various products that meet the customers' requirements.

Main classifications & features of Double girder gantry cranes

Based on different standards, the double girder gantry cranes can be grouped into different types and in the following, the main types of double girder gantry cranes and their main features are presented for your reference. If you want to know more information and specifications, please feel free to contact us.

Full gantry crane vs. Semi double girder gantry crane

In terms ofstructures of gantry frame,gantry crane can be grouped into full gantry crane and semi gantry cranes, etc.

Full gantry crane are double legged gantry crane, main girder supported on the two legs, which are in the same height, featured as high safety, durability and cost-effective for not supportive columns or building structures are required. Double girder gantry crane with full gantry crane designs are usually adopted for heavy duty , large volume, or difficult loads handling and they are applicable to harsh applications with process crane designs.

Semi gantry crane is a variant of regular gantry crane with one end supported on a leg running on the ground rail and the other end travelling overhead on wall mounted track, therefore also called Single Leg Gantry Cranes. The single leg semi gantry cranes offers a cost-effective solution for factory or applications with narrow, confined spaces or crowded machinery.

Double Girder gantry crane

Double girder gantry cranes & double beam gantry cranes overview on gantry crane specifications, gantry crane types, features, crane usages & applications.

Single girder gantry crane with semi-gantry design 

BMH Semi Single Girder gantry crane 1t to 16t.The single girder semi gantry crane is a general purpose light crane used in workshop or outdoors.

Double Girder gantry crane with semi gantry design 

BMG Semi Double Girder gantry crane 5t to 32t. Semi Gantry Crane can be divided into double girder truss type semi gantry crane, and double girder box-type semi gantry crane.

Box girder gantry crane vs. Truss girder gantry crane

In terms of crane girder designs of double girder gantry crane, double girder gantry cranecan be grouped into box girder gantry crane, truss gantry crane,etc.

Box girder gantry crane -The box shaped gantry girder is welded with steel plates , with features of high safety, stiffness and other, etc. . Box gantry girder design is usually used for double girder gantry crane with large and super large tonnages.The box gantry girder design also has the draw backs of high production cost, heavy selfweight and poor wind resistance.

According to gantry girder design, double girder gantry crane can be grouped into - box shaped girder design gantry crane and truss girder design gantry crane . At present, box-shaped girder design gantry crane is more frequently used.

A frame double girder gantry crane & U shape leg double girder gantry crane

Based on the different designs of supporting leg, the double girder gantry crane can be grouped with A frame gantry crane, L frame gantry crane, and U frame gantry crane

A-frame cranes usually refers to A frame double girder gantry crane which is a specialvariation of regulardouble girder gantry crane, with A shape like side profile. With various crane specifications and crane configuration, our A frame double girder gantry crane can be used for light, medium and heavy duty material handling, which includes the following of double girder gantry crane:5ton ~50ton light duty & medium duty hoist trolley gantry crane, 5ton ~320ton heavy duty open winch double girder gantry crane, and process designed double girder gantry crane, etc.

U frame leg double girder gantry crane usually refers to the Rail Mounted GantryCrane, shorten as RMG crane which is a type of container cranes for lifting the international ISO standard containers.AdoptingU frame supporting legs , the rail mounted gantry crane has wider clear space than the regular gantry crane, which enables containers move to sides easily. The whole RMG crane with the capacity of 30 ton-50 ton is designed to run quicklyand steadilyon the fixed gantry rails on ground for efficient container handling inoutdoor workplaces, such as, port and dock, etc.

A frame gantry crane

A frame crane design & manufacture：5 - 50 ton single girder & 5 - 320 ton double girder Fixed A frame gantry cranes & 0.5-10 ton Portable A frame crane for reliable material handling.

U frame gantry crane

The U-type double girder gantry crane is a type of heavy-duty lifting equipment that differs from A-frame gantry cranes in that it has more space between legs, allowing it to lift and carry large-sized products such as containers.

Applications of double girder gantry crane

Double girder gantry cranes and double beam gantry cranes are widely used in varioua industrial application. The industrial gantry cranes are usually used in the following industrial applications such as,

Precast yards,Ship building,Mining Maintenance ,Bridge construction industries to name a few.
