Abstract

A safety device against the risk of accidental electric contact between a machine (1) for yards or for handling material or the like and an electric cable under voltage (3), comprising a sensor (7) for sensing the electric field or electromagnetic, located in at least one predetermined point of the machine on a zone of end or on an arm (12), and an emergency device comprising means for blocking the displacement of the machine when the machine reaches a predetermined critical distance of danger from the electric cable under voltage, and/or warning means (9) of proximity associated with the sensors (7), capable of emitting a warning signal that informs the operator at reaching a critical danger position and at approaching to the critical distance.
