<p>A screw jack mechanism for lifting and sinking of loads comprises a bearing post (1) with the exterior thread, which enables a driven threaded nut (2) to displace a guide (3), its suspended parts (4), (5), (6), and the load (7). The guide (3) is sliding along the exterior perimeter of the bearing post (1) thread taking over the force components perpendicular to the force of the load (7), while the threaded nut (2) is taking over the axial forces indirectly. A bolt (4) inserted into the guide (3) is sliding within the groove of the bearing post (1) preventing the turning of the guide (3). The guide (3) is supporting a bearing (5) with a turnable console (6), which is bearing the load (7).</p> |
