1. DEVICE FOR TIGHTENING LARGE THREADED CONNECTIONS, containing a pressure working element made in the form of a base plate with a central hole and symmetrical conical inserts at its end, a pressure plate with an axial hole fixed in its center of the glass and the power element interacting with the bottom glass and designed to act on the bolt or stud of the threaded connection, and the power wedge mechanism, including a pressure screw, a central wedge with an inclined symmetrically arranged relative to it interacting with the pressure screw and two asymmetric wedges placed between the conical liners and the pressure plate and interacting with large bases with symmetrically inclined inclined surfaces, characterized in that, in order to increase reliability, it is equipped with cidander guides fixed to the ends of the central wedge, contacting one with the surface of the axial hole of the pressure plate, the other with the inner cylindrical surface of the glass, and clamps that bind and a support plate between the central wedge and the pressure plate and prednaznachennysh to prevent circumferential rotation with respect to each other. 2. The device according to p. ends with longitudinal grooves.
