The measure of the tensioning of cables and ropes it is carried out with special measuring instruments that allow the evaluation of the tension of the element under test through the forces exerted on pulleys that support the cable or the rope.
The measurement of the tension carried out with this technique allows the relief also with the rope in operation and without detachment of the load.
Cable tensiometers can be supplied with standard calibration, obtained on commercial rope, or with special calibration on non-standard rope.
