Abstract
Load limiter making it possible to set off an electric signal subsequent to a tensile stress exceeding a certain maximum value. It is based on the principle of rotation by axial stretching of a twisted part, the said rotation deplacing an armature of an electric contact switch.
Claims11
Load limiter for lifting devices, setting off an electric signal when a vertical tensile stress is greater than a maximum value and constituted by a housing, a flexible system subjected to the said vertical tensile stress adapted to actuate, due to its movement, an electric contact switch, characterized in that the said flexible system is previously twisted in its middle part and stretches by rotation in a plane perpendicular to the direction of the vertical stress.
