<p>The pulley has a ring-shaped rotational guiding element (2) with an external surface (S1) forming a groove guiding a cordage, and rotationally mounted on an annular support structure (ST), which includes fixation units for fixing another cordage. Detectors (12-15) i.e. strain gauges, are placed inside the structure to produce information in the form of an electrical signal, where the information represents strains exerted between the cordages. The detectors are connected to remote transmission units that transmit the information to a central processing and calculation unit.</p> |
