This is a wagon design based on 2 End-Carriages solution running on a floor mounted runway-rails. Instead of a hoist unit it is carrying directly the load or product. Found mostly to shift products from one production area to another. In our factory we have a traverse wagon shifting our bridges into the sandblast and painting area and back.
