Abstract (en)
[origin: FR2901548A1] The unit (1) has a proximal part (1a) fixed to a lifting apparatus and a distal part (1b) connected to a load to be lifted. A longitudinal section (1c) is developed from the proximal part in a direction of the distal part and is elastically elongated under an action of a part of lifting effort. An optical fiber stress sensor (2) having reduced diameter is inserted into a longitudinal channel (1d) of the section and is fixed to a lateral wall of the channel. A connector (3) transmits signals from the sensor to a sensor signal reception and analyzing unit (4).
