Crane girder:

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!

1. the Bridge Crane, which traverses across the runway
2. the hoist & trolley, which traverses across the bridge and lifts up and down
3. the runway, which is tied to the building structure.  

Top Running vs. Under Running

1. Capacity - Although under running can be up to *5 ton capacity, the practical limit is more like *5 tons and the economic sweet spot is 1 to 7.5 ton range.
2. Support Structure - Under running can be suspended directly from the overhead steel (for lighter cranes). Top running cranes will require a bracket off the building support steel (up to *0 tons capacity) or independent columns for heavier capacities.
