Abstract: The invention relates to a load limiter for lifting apparatus which triggers an electric signal when a vertical tensile stress exceeds a predetermined threshold, the constitution of said load limiter allowing a smaller lost height. The limiter according to the invention is characterized by the fact that it comprises two blocks which extend horizontally on either side of a a narrow common portion which forms a pivot so as to delimit a free space extending between the two essentially vertical facing surfaces of said blocks and at whose open end said elastic system is disposed horizontally and in that two fixed supports are provided on either side of said common portion to bend said load limiter. Application to electrical lifting devices such as hoists.

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.
