When lifting the electrode, the cushion pad is softened to the bottom of the end of the connector of the spare electrode assembly to prevent ground damage and damage to the connector; the lifting hook extends to the lifting ring of the lifting device to lift, the lifting electrode is smooth, preventing the electrode from releasing from the B end or fixing with Device collision.
The second is to suspend the spare electrode above the electrode to be connected, align the electrode hole, and then slowly drop; rotate the spare electrode to make the screw hook rotate with the electrode to fall down. When the electrode is finally lowered completely, do not use excessive force, otherwise the electrode hole will be damaged. Violent collision damages joint threads and more.
