Double Girder Overhead Crane

A double girder overhead crane is a form of crane that includes two beams running parallel to one another. These beams support a platform, which is often used to move heavy loads. Double girder overhead cranes are generally used in factories and warehouses, where they are utilized to advance materials around the facility. As the crane features two beams, it is more stable than a single girder overhead crane. Because of this, double girder overhead cranes are more unlikely to tip over, leading them to be safer to use.

Double Girder Overhead Crane has two bridge beams instead of one. An additional 18”- 36” of hook height is gained with this type of crane since the hoist can be placed between or on top of the beams.

With no maximum span or capacity restrictions, double girder overhead cranes are ideal for manufacturing and transporting heavy equipment.

Other components, including walkways, service platforms, cabs, magnetic reels, and lighting, will be supported by a twin-beam design. Therefore, double-girder gantry cranes are more reliable.

The double-girder bridge crane can be used indoors in metallurgy, steel, casting, insulation, etc., and has strong environmental adaptability.

Single and double girder overhead cranes all are our main products. There are some differences in loading capacity and height, span, installation process, and machine cost. You can choose a suitable overhead crane according to your needs. Further details about the differences as below.

One of the main differences between single girder and double girder cranes is their load capacity. Double girder cranes are designed to handle heavier loads, making them ideal for industries requiring the movement of large, heavy items. In contrast, single girder overhead cranes are more suited to light to medium-duty applications.

 

Double girder cranes generally offer a greater lifting height and span than single girder cranes. This is because the trolley and hoist system can be positioned between the two girders, allowing for more vertical space for lifting. On the other hand, single girder overhead cranes have the trolley and hoist system mounted below the girder, limiting the available lifting height.

 

Single girder cranes usually have a lower initial cost, as well as a simpler and faster installation process. This makes them an attractive option for businesses with budget constraints or limited time. However, double girder cranes, while more expensive and complex to install, provide greater capabilities and flexibility for heavy-duty applications.

Do you have a plan to purchase a single girder overhead crane? Before the order, you should confirm your requirements, such as your application environment, lifting capacity and height, span, etc. Therefore, the suppliers will provide you with a personalized machine based on your needs.
