In 1974, the locomotive and wagon Works were merged under the name of Railway Vehicle Factory and then the machine construction branch went through significant development. The production of industrial and apartment house lifts became a new branch. Ganz-MÁVAG took over a lot of smaller plants in the 1960s and 1970s and their product range was extended. Among other things, they increased their bridge-building capacity. They made iron structures for several Tisza bridges, for the Erzsébet Bridge in Budapest, for public road bridges in Yugoslavia and for several industrial halls.
