- One leg on a ground rail, one end on a runway
- Uses the building column line
- Single or double girder
- Indoor or outdoor
What it is
A semi-gantry combines a gantry leg on one side with an overhead runway on the other – usually the column line of a building. It serves a strip along the wall inside or outside the building without a second runway, a common solution for loading areas and lean-to bays.

When is a semi-gantry used?
Where one side can use an existing building runway and the other side needs a ground rail – for example along a building wall.
