The ‘Buggi’ system was developed in the early 20th century by the Luxembourgish engineer Albert Hames. It is a tilting cart used for transporting iron ore from shallow mines, as was common in Luxembourg. In France, on the other hand, mines were primarily accessed through shafts, and a different type of cart was used. Unloading French carts required a large facility to flip them completely upside down. This is where the advantage of our Buggi lay, as a single person could tilt it using a lever and muscular force.
