  • Conductor transfer device
    Patent number: 4365410
    Abstract: A device enabling movement of an electrical conductor through a string of insulators coupled between a supporting tower and a yoke plate. An upper frame having clamping jaws for engaging one of the insulators is pivotally mounted to a lower frame connectable to the yoke plate. A hydraulic cylinder causes the frames to rotate relative to each other, to relieve stress on the lower portion of the insulator string, so that it can be uncoupled to permit movement of the conductor through it.
