Abstract
The present invention provides a cable driving wrench assembly for thrusting and rotating a multi-strand cable mine rock anchor. The wrench assembly includes a wrench body having an open interior and a plurality of apertures in the wrench body extending into the open interior. Each aperture is adapted to receive an individual strand of the multi-strand cable when the individual strand has been separated from the remaining strands of the cable at least at one end of the cable. The open interior of the wrench body is adapted to receive one end of the cable through the plurality of apertures. A mechanism for thrusting and rotating the wrench body is attached thereto. The present invention additionally includes a cable opening tool for opening the strands of a multi-strand cable. The cable opening tool includes a rotatable tool body and a socket formed in the tool body. The socket is engageable with one end of the multi-strand cable to separate the individual strands from each other at one end of the cable upon rotation of the tool body.
