Title:

CABLE GRIPPERS

Document Type and Number:

WIPO Patent Application WO2007080384

Kind Code:

B1

Abstract:

With one known cable gripper device, when the gripper device contacts the outer surface of a submarine telecommunications cable, there is a problem of insufficient friction between the cable layers being acted on by the gripper, and/or insufficient adhesion between the cable layers along the cable from the gripper to the free end of the cable, and consequently there is a tendency for the protective outer sheath to be stripped from the core during recovery, with the result that the engaged end is lost. The cable grippers (100) of this invention are able to penetrate the outer protective layer and to grip the inner tensile strength core of cable. They may have at least one pair of co-operative gripper members (15a, 15b), the inner ends of which are profiled to together define a pre-shaped gripper for secure engagement of cable, providing an inner region to receive and retain the inner tensile strength portion.
