Single Girder and Double Girder Top Running Crane

Specifications

What Is A Top Running Crane?

In general, top running crane refers to top running overhead crane. Top running cranes run on a fixed rail or track system on the top of each runway beam. As the whole crane systems run on the rails, so they are called top running crane. They can be configured in a single girder or double girder bridge design and are ideal for moving extremely heavy loads.

According the bridge design, a single girder top running crane utilizes an underhung trolley and hoist as lifting mechanism, while a double girder top running crane most often utilizes a top running trolley and hoist (double girder crab hoist or open winch) as lifting mechanism.

What Are The Top Running Crane advantages?

1. Top running overhead cranes have no limiting capacity
2. As the crane systems are supported by the building structure or columns, they can easy handle the capacity from 500kg to 500 tons loads. Normally, a single girder tope running crane can lift up to 20 tons, while the lifting capacity of double girder tope running crane is up to 500 tons.
3. More higher lifting height. Top running cranes provide added lift height for buildings with limited headroom because they ride on rails on top of the runway beam.
4. Top running cranes can accommodate wider spans.
5. Installation and future service or maintenance of top running crane is easier and less time
6. Top running cranes have faster lifting and travelling speed, more efficient.

In view of the above advantages, top running cranes are the most widely used crane types.
