What is a top running overhead crane? It is a crane that has two runway beam and a fixed track or rail system is installed on top of each runway beam. It has an end truck that carries the hoist and bridge on top of the runway system. It is also configured in a double girder or single girder bridge design.
These top running overhead cranes can handle both small capacity and large capacity loads. Therefore, they do not have a limiting capacity. They are built to capacities from ΒΌ ton to around 100 tons. They have a strong structure that supports them. And they have runway support columns for transporting heavy loads.
These cranes are perfect for buildings with limited headroom. This is because they provide an added lift height and they ride on rails on the runway beam. For example, a top running double girder bridge allows the greatest lifting height. Why? Because of the trolley and hoist on top of the two girders or bridges that add extra 3 to 6 feet of hook height.
These cranes are large. So, they can lift heavy loads. In fact, they are larger than the under running cranes. Additionally, they are large because they are built to higher capacities. Therefore, they can accommodate wider spans. They are good for lifting heavy loads.
However, the rail or track system can get damaged easily. If there is a problem with this system, it can lead to alignment or tracking problems. Therefore, you need to check or inspect this system regularly. Fortunately, it is easy to do these inspections. And the inspection requires less downtime.
What are the applications of top running overhead cranes? They are used to transfer and loads goods in material yards, workshops, and warehouses. They are used in building that has limited headroom because they provide high headroom. Also, they are used to lift large and heavy loads.
They can also solve heavy service duty problems. They are the most powerful solution for lifting heavy loads because they allow the incorporation of a variety of hoist brands. They are used in both single or multi hoist applications. And they offer maximum design flexibility.
This crane has end trucks that are made of structural steel tubes. The design of the end truck makes it easy to remove and exchange the wheels of these end trucks. Additionally, these trucks are fitted with shock-absorbing bumpers. And it is easy to remove the end truck because it is bolted for easy removal.
Want to choose the right top running overhead crane? If yes, choose a crane that is suitable for the load you want to lift. The overhead room available determines the type of crane you will choose. Additionally, you need to consider the height before choosing this crane. If there is an existing support structure, choose a crane that can easily be supported by that structure.
This an overview of the top running overhead crane. If you have been thinking of buying this crane, you should buy it. Buy the right crane that is suitable for your business. Choose a crane that can easily lift the materials you want to move.
