Abstract

E' previsto un gruppo (20) di controllo dell'azionamento del motore elettrico (7) e un dispositivo (30) di controllo, elettricamente collegato al corpo dell'operatore (10), che agisce, tramite un mezzo a relè (40), sul gruppo di controllo (20) in modo da arrestare ed invertire la rotazione del motore elettrico (7) a seguito di contatto conduttivo tra il corpo dell'operatore e il componente metallico (3). Sono previste due piastre conduttive (12) e (13) atte a ricevere in appoggio i piedi dell'operatore (10), isolate dal suolo e poste in posizione tale che l'operatore appoggi i propri piedi con scarpe conduttive su esse quando lavora con la macchina; dette piastre (12) e (13) sono collegate con il dispositivo di controllo (30); il componente metallico (3) è collegato elettricamente a terra; le piastre di appoggio (12) e (13) sono elettrodi per il passaggio di corrente elettrica a bassa tensione da una piastra all'altra attraverso il corpo dell'operatore (10); il dispositivo di controllo (30) comanda l'arresto del motore (7), a seguito di contatto conduttivo tra le mani dell'operatore e il componente metallico (3).
