<p>A cable anchor for preventing longitudinal movement of a cable (30) within a conduit (28) to transfer the weight of the cable to the conduit, comprises a housing (36) connectable to the cable. An arm member (46) is connected to the housing (36) and is movable from a retracted position to an extended position in gripping contact with an interior surface of the conduit (28) to thereby transfer the weight of the cable to the conduit. A piston and cylinder assembly (52, 58), operable from fluid pressure within the conduit, is connected to the housing (36) and in operable contact with the arm member (46) to extend the arm member. <IMAGE></p> |
