Abstract

The invention relates to a force sensing device which is to be inserted in a force transmitting structural member, like a rope, especially a rope for lifting a jib or a load of a crane. The force sensing device has a flat body provided with weak locations at which strain measuring devices are fixed. The flat body is dimensioned with respect to a high degree of safety against overload, to high duration working stability and reproducibility as well as to a simple and cheap production.
