Bridge cranes are also known as overhead cranes that easily include a couple of overhead runways. However, these are typically built into the supporting structure of the building. As such, some include two beams and are referred to as double girder cranes. So, read on as we dive into everything that you need to know about double girder overhead cranes.
Double girder overhead cranes are known for being stronger and providing more hook height. This is since the hoist and the trolley are placed at the top of the girders. The bridge of the double girder crane is made up of two girder beams that are supported by end trucks on either side.
For the most part, the hoist and the trolley run on the rails as opposed to the girders. With this type of design, up to 36″ of extra hook space is created. As such, the double girder crane can be either run on top or even under the initial design of the structure.
Double girders that run on top of the crane are known for providing a significant degree of room and a great deal of hook height. Because of their structures, these are better suited for extra heavy and heavy-duty uses over extended periods. As a result, the components include the trolley and the hoist. However, more complicated designs are very expensive.
It should be noted that double girders tend to need a lot more material for the bridge and the runway components. This just simply means that you’ll need to pay closer attention to the structure of your building before you purchase one of these. Additionally, support columns or even tie-backs may be required so that you can properly support the overhead crane.
As previously mentioned, double girders are perfect for lifting all of your heavy loads. They are also ideal for faster and more efficient operations in your warehouse or business. Unlike some types, double girders can be used either outdoors and indoors as desired. A double girder is suited for railyards, steel or iron production, mining, and shipping ports.
The main advantages of the double girder overhead crane are that it not only allows a greater hook height but it is also very high above the floor. With the double girder, you’ll easily be able to make use of up to 36″ of space higher. Additionally, there’s no maximum capacity or span with the double girder.
Unlike others, it can also be used to transport heavy equipment and for lifting a lot of heavy loads. If you’re interested, you can also add cabs, maintenance platforms, lights and magnetic reels. As previously stated, these are suited for both indoors and outdoors. Hence, they’re used in rail yards, steel and iron production, mining, and on ports.
Just like with any other piece of equipment, you can expect that there are some disadvantages. These include the cost since more materials are required. The cost to install is also higher when compared to others. The last main downside is that the hook approach is less.
As we conclude, we have just looked at everything you need to know before purchasing an overhead double girder. These are strong and well suited for tons of uses. So, it’s best to consider all of this before deciding to purchase the double girder for your business via opening this website crane.pk.
