Top Running vs. Under Running
Top Running vs. Under Running is primarily determined by two factors:
1.Capacity - Although under running can be up to 25 ton capacity, the practical limit is more like 15 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 10 tons capacity) or
independent columns for heavier capacities.
The top running configuration is best used in cases where the end user has issues with headroom. The most space
efficient configuration is the double girder, top running crane system. When headroom is not an issue a top or
under running configuration can be used with either the double or single girder bridge crane.
