ABSTRACT:
An apparatus for unseating wire rope wedges is accomplished by means of a linear motor such as a hydraulic jack mechanism. The hydraulic jack includes a housing structure adapted to be seated about a portion of a wire line connector device in such manner that a force transmitting retained relationship is established between the housing and the wire rope connector. A linear actuator within the housing is energized against the small end of a wire rope wedge and accomplishes movement of the wedge to its unseated position to release wire rope secured thereby.
