Abstract:
A lifting apparatus for transporting a carbon based electrode having a threaded male end. The apparatus includes a casing having a top end and a bottom end. The casing defines an electrode aperture from the bottom end shaped to accept the threaded male end of the carbon based electrode to secure the lifting apparatus to the electrode. An attachment aperture is positioned in the top end while an attachment element is positioned in the attachment aperture and operatively engaging the top end of the casing. The attachment element is positioned to accept engagement from a crane or other powered lifting device, while the lifting apparatus is preferably manually attachable to the electrode.
