Control equipment for lift doors includes a support structure (12) having guides (24, 26) along which two carriages (20, 22) for carrying respective door panels (16, 18) can run. The equipment includes a screw (34) and nut (40) drive mechanism associated with a motor (32) and adapted to drive the translational movement of the slower carriage (20). A flexible transmission member (50) is interposed between the slower carriage (20) and the faster carriage (22) and cooperates with a pair of transmission members (48) carried by the slower carriage (20). <IMAGE> |
