Abstract (en)
[origin: US4437187A] An electric furnace includes a lifting structure actuating a furnace cover and comprising a stationary supporting post. A lifting means is axially displaceably guided on the stationary supporting post by an upper and a lower bearing. The lifting column is liftable and lowerable by the lifting means and engageable with, and disengageable from, the furnace cover. In order to provide a lifting structure that enables either a lower construction height or substantially slighter forces in the bearings of the lifting column, the hollowly designed lifting column peripherally surrounds the stationary supporting post. The lifting means is articulately connected with a head plate closing the lifting column on its upper end and with a stationary part of the plant.
