Under Runing Crane Vs. Top Running Overhead Crane:

Support structure: Underslung cranes can be suspended directly from the roof structure or other overhead beam. Top running cranes need independent columns to support the end trucks and the bridge beam.
Capacity: As underslung cranes are suspended from the roof structure, they are available only on lighter capacities, usually less than 16 tons. The capacities of top running overhead cranes are much larger. The safe working load of top running cranes can even up to 500 ton.
Configuration: Because of the light capacity, underslung cranes usually adopt the single girder configuration, although double girder under running crane is also available in some special cases. But the top running overhead crane equipped with double girder is more frequent.
Utilization of space. Something unique to underslung cranes is their ability to make full use of the available height and the tight space. They can ensure efficient material handling even in plant where very little space is available.

How to Choose Underslung Crane：

To install an underslung crane, the roof structure must have the ability to withstand the weight that imposed by the underslung cranes itself and the load.
