This automatic barrier is planed in a rational way to consent a quick movement also to the long barriers.
The barrier is moved by an electromechanical thrust mechanism with a gear motor connected with a recordable balancing springs system, a mechanical stroke end with microswitches.
It is drived by our control console. In case of current failure you can move the barrier through a crank.
Body is galvanized sheet-iron for a greater time resistance; shutter protected by a lock.
It is necessary the utilisation with counter-weights in the case of the bar is longer than 4 mt. combined with the apron.
