摘要:
Unloading apparatus for vacuum electric furnaces having a hostile environment is disclosed in which a compartment is provided to which work pieces are delivered from such a vacuum electric furnace, transferred from the furnace by movable supporting and transferrng arms which are normally in the hostile environment onto an elevator platform at a central location and then elevated for transfer to other equipment, all under vacuum. The movable arms are first raised and then turned by hudraulic actuators and the elevator platform is also positioned by a hydraulic actuator. The elevator platform and its enclosure are normally screened from radiant heat by a door which is swung from a vertical position for shielding to a horizontal position to permit access of the movable arms and the work pieces thereon to the elevator platform.
