Abstract
Cat device for the tensioning of cables in prestressed concrete constructions, more particularly of cables provided with a traction head that serves as means of grip and an anchor head that serves to fix the cable to the corresponding end of the construction of concrete, said jack being characterized in that it is constituted by a cylinder a completely open end of which forms a support base, and a piston that slides in said cylinder and that presents an axial recess for receiving a traction head provided with means of coupling for said head, the piston being integral with a large diameter rod having an axial recess extending the piston and bearing, at its free end, a skirt sliding on the outside of the cylinder in such a way that the space between said skirt, the piston rod, and the corresponding end of the cylinder, constitutes a fluid intake chamber under pressure to ensure the working lengthening stroke of the jack, while the space between the annular surface of the piston and the bottom of the cylinder constitutes a pressure fluid intake chamber to ensure the shortening or return stroke of said jack .
