Underhung and Under-running cranes are two ways to refer to the same type of crane. With underhung cranes, the end trucks ride on the bottom flange of the runway beam rather than on top like other types of overhead cranes. With an underhung crane, the runway beam is often suspended from the roof, which eliminates the need for extra floor columns to support the runway. This can be advantageous if floor space and the need to reduce obstructions is a major issue in the factory or warehouse. An underhung crane may even be appropriate with sloped ceilings or multiple crane systems.
