CASSA DI MANOVRA PERFEZIONATA PER DEVIATOI FERROVIARI

A switch machine for railroad switches (1) comprises a movement group (20) provided with at least an operating tie-rod (20a,20b) engaged at opposite ends (21,22) to a first and to a second switch point (101,102) by respective movement transmission members (40a,40b). The operating tie-rod (20a,20b), in use, translates along a movement direction (120) in order to shift the first and the second switch point (101,102) between two limit positions. An actuation group (70) is then provided operating the translation of the, or each, operating tie-rod (20a,20b) along the movement direction (120), and a locking/unlocking group (50) movable between a locking configuration, in which it prevents the above disclosed translation of the, or each, operating tie-rod (20a,20b), and an unlocking configuration, in which it permits the above disclosed translation. The switch machine (1) provides, furthermore, a first control rod (31) and a second control rod (32) movable independently one with respect to the other, and configured in such a way to translate along a direction parallel to the movement direction (120).
