<p>There is a coupling bar (16) which is fastened to the frame (10) through a first hinged joint (26) whose pin is transversal to the tensile force direction. This bar is connected to the other jaw (34) through a second hinged joint (30). The distance between hinge pins (26,30) is such that the distance between jaws (34,36) is smaller than the dia. of the cable when the coupling bar is perpendicular to the fixed jaw (36).</p> |
