Abstract: A cable gripping assembly. The gripping assembly has two jaw assemblies for gripping and pulling a cable. Each jaw assembly has a jaw block with a tapered cavity, and a jaw subassembly which fits within the tapered cavity to grip a cable when frictional forces, caused by a hydraulic cylinder or other actuator, force the jaws into the tapered cavity. The jaw subassembly has a guide plate, which carries pins affixed to the jaws. The guide plate is ordinarily allowed to move the pins along angled slots in a jaw plate. However, when actuated by a plunger, the guide plate and pins are forced to a widest point of the angled slots, maintaining the jaws in an open position, allowing for easy removal of the strand from the gripping assembly.

Abstract: An apparatus for gripping and pulling a wire strand. The apparatus is carried by a cylinder assembly attached to a frame. The cylinders provide force to pull the strand. Jaws are situated in a jaw block, and are tapered such that movement of the jaw block by the cylinders will tend to force the jaws closer to one another within a tapered cavity. Movable, spring-loaded J-rods are provided to retain the jaws within the jaw block when desired. The J-rods can be rotated to a position which does not retain the jaws when the wire strand is being added to, or removed from, the apparatus.
