Abstract
An electric arc furnace has a body mounted on a pivotable platform and electrodes which extend through a furnace cover. A gantry supports the cover and electrode and is mounted on a rail for swinging movement onto and off of the platform to move the cover and electrodes from above the furnace body to a remote position. A pair of support columns are mounted below the edge of the platform over which the gantry moves and each column is pivotal into and out of a vertical supporting position to permit the platform to pivot. Shock absorbers limit pivotal movement of the platform in each direction and cushion engagement between the platform and the columns.
