A controlled tension cable transport system is disclosed, comprising a pulley with fixed axis and a second pulley whose axis occupies a position which is normally fixed during operation. Four sensors measure the tension of the cable during a previous test phase, with the installation off load, and a computing and control assembly compares the measurement results obtained with admissible limit values, for allowing or preventing operation of the installation. Preferably, the computing and control assembly permanently compares the tension of the cable and the torque of the pulley with respect to admissible threshold values during operation of the installation.
