A gripping tool has at least one body, including an associated load adaptor adapted to be connected to and interact with one of a drive head or reaction frame. A gripping assembly, carried by the body, has a grip surface adapted to move from a retracted position to an engaged position to radially engage one of an interior surface or an exterior surface of a work piece upon relative axial displacement of the body relative to the grip surface in at least one axial direction. A fluid activated grip activation assembly acts between the at least one body and the grip surface. Axial movement of the load adaptor displaces fluid into a fluid chamber between the at least one body and the grip surface to create relative axial displacement of the at least one body relative to the grip surface. |
