  • Anode butt remover
    Patent number: 4442593
    Abstract: Anode butts are removed from the studs of anode rods by stripping the butts from the studs in a downward direction by hydraulic cylinders, the counter-forces of such action being taken up by the yoke which carries the studs. The stripping forces are thus absorbed inside the device and not transferred to other parts of the structure. The butts are stripped off the studs with only slight crumbling.
