Abstract

A safety system operating as follows: when someone gets too close to the power take-off or the driven machine, a rocker system A actuated by a sensor or an electronic beam immediately and automatically blocks the rotational motion of the cardan drive and separates it from the power take-off. As a result, the machine stops and is no longer driven, the cardan drive falls to the ground and stops moving so that it no longer threatens to cause an accident or injure the user or a careless onlooker.
