Tipping safety device, characterized in that it consists of a cam disk that remains fixed to the motionless structure of the crane during the lifting and lowering maneuvers of the load and of the boom, and of a switch integral with a housing whose inclination it has a one-to-one relationship with the inclination of the boom so that, depending on the inclination of the boom, the operating lever of the switch faces one or the other portion of the cam disk; said switch is oscillatingly mounted around a pivot so that by turning a certain angle the support of the actuating lever against the cam is verified, the amplitude of said angle varying as a function of the relative position of the pivot of the switch and of the cam.
