One of the first reasons why you should invest in a double girder overhead crane is the fact that it is able to provide an extra 18-36 inches of hook height. This is due to the fact that the trolley and hoist have been placed between the top of the cross girders.
There are two girder beams on the double girder crane, these make up the bridge of the unit and are supported with an end truck on both sides Typically, you will find that the trolley and hoist will run on a rail that has been installed on top of the bridge girders. The benefits of the double girder design in your workplace is the fact that you are going to be able to gain the depth of the cross girder. This happens when the hoist is placed on top of the cross girders. This will help to place up to 36 inches of extra hook height. http://overheadcranesmanufacturer.com/double-girder-overhead-crane/
You will find that girder cranes are either under running or top running in their design. For the most overhead room and greatest hook height, a top running double girder bridge crane is recommended.
Typically, double girder cranes from Weihua are used in instances where the crane is needed for heavy-duty work such as heavier loads and longer time spans. With this in mind, the components of these cranes are much more complex, which is going to make them more expensive than a traditional single girder crane.
Double girder cranes also come with the ability to be upgraded with specialized features like maintenance platforms and walkways.
These types of cranes are also going to need more material for the runway system and bridge beams, so it is essential to reconsider your buildings support structure. You may need to invest in more support columns and tie-backs to handle the excess dead weight that will be added to the foundation and support of the building.
When of the main benefits for many construction crews is the fact that more work can be accomplished with the double girder crane. It has the potential to be used for much longer extended periods than a single girder crane. However, both types of cranes can be used in similar settings such as mining, shipping ports, rail yards, and in outdoor and indoor settings.
The Benefits Of Owning A Double Girder Crane
– The greater hook height allows for up to 36 inches more space than the single girder.
– One does not have to worry about maximum span or capacity.
– This type of machinery is ideal for heavy equipment and loads.
– The double girder design has the ability to be maximized for performance with specialized add-ons such as cabs, walkways, and lights.
The double girder crane can be used indoors or outdoors in a wide variety of settings including mining operations, shipyards, and railways.
Disadvantages of a Double Girder Design
While we can sing the benefits of the double girder design, it does come with a few disadvantages. Primarily, due to the complex components, design and materials, this crane is going to be more expensive than its single crane counterpart.
There are also additional costs due to installation and shipping that are not associated with the single girder crane.
There is also a lessened ability with the hook approach on the top running double girder cranes with trolley and bridge travel.
