ABSTRACT:
Apparatus for cleaning accumulated spent alumina, dross, aluminum pads, refractories and carbon rods from an aluminum cell including a first platform supported on outrigger members for spanning the open top of the aluminum cell. The ends of the outrigger members carry edge clamping and traveler devices thereon which are alternately activated by hydraulic cylinders. In a locked position, the outrigger arms resist lateral and upward forces imposed by the digging and cleaning tools of the apparatus. In an unlocked position, the traveler devices support the outrigger members on an adjacent surface for movement along the cell. A turntable carrying a second platform is rotatably mounted on the first platform to permit 360.degree. rotation of the second platform. A mounting head is pivotally mounted on the second platform and carries an elongated extensible boom for controlled 360.degree. rotation about the longitudinal axis of the boom. A forward end of the boom includes a hydraulic cylinder for effecting pivotal movement of a detachable tool such as a hydraulic chipping hammer or a bucket scoop.
