The invention concerns a lifting member (1) for transmitting all or part of the lifting force between a lifting appliance and a load to be lifted, comprising: a proximal portion (1a) configured to be fixed to the lifting appliance; a distal portion (1b) designed to be connected to the load; a longitudinal section (1c), extending from the proximal portion (1a) towards the distal portion (1b), and capable of being elastically elongated under the action of part of the lifting force; a longitudinal channel (1d) extending from the proximal portion (1) into the longitudinal section (1c) of the lifting member (1); a stress transducer (2), inserted into said longitudinal channel (1d), and fixed to the side wall of said longitudinal channel (1d); linking means (3) for transmitting optical fiber signals from the stress transducer (2) to means for receiving and analyzing (4) optical fiber signals from the stress transducer.
Organe de levage (1 ), destiné à transmettre tout ou partie de l'effort de levage entre un appareil de levage et une charge à lever, comportant : - une partie proximale (1 a) conformée pour être fixée à l'appareil de levage, - une partie distale (1 b) adaptée pour être reliée à la charge, - un tronçon longitudinal (1 c), se développant depuis la partie proximale (1 a) en direction de la partie distale (1 b), et apte à s'allonger élastiquement sous l'action de la partie de l'effort de levage, - un canal longitudinal (1d), s'étendant depuis la partie proximale (1 a) dans le tronçon longitudinal (1 c) de l'organe de levage (1), - un capteur de contraintes à fibre optique (2), inséré dans ledit au moins un canal longitudinal (1 d), et fixé à la paroi latérale dudit au moins un canal longitudinal (1d), - des moyens de liaison (3) pour transmettre les signaux du capteur de contraintes à fibre optique (2) à des moyens de réception et d'analyse (4) des signaux du capteur de contraintes à fibre optique (2).
