<p>First the column (1), on the upper part supporting the electric motor reducer group (2), is placed on the base (3) screwing into the central inside threaded hole (4) of the said base the axial thraded support (5) and then blocking on the upper position with a lock nut (6) and in the lower position with the lock nut (7). Then on the motor reducer (2) a ferrule (8) is placed to support a thrust bearing (9) blocking with a traction flange (10) and then fixing with a blocking screw (11). On feeder (12) a low voltage transformer (13) is mounted using a satety valve (14) and a microswitch (15) to turn on a light (16). At the end the mobile part of the cylindrical coaxial means is placed formed by a supporting rotating part (17) with on the upper part the spaced out supports (18) for the disk-shaped shelves (19), all the components kept in position lowering by the lock nut (20) and on the upper part by the plug (21). <IMAGE></p> |
