Abstract:
A tensioning and tension-measuring device (1) of a rope (3) is described, comprising a first supporting means (5a) of a first end (3a) of the rope (3); a second supporting means (5b) of a second end (3b) of the rope (3), the second end (3b) being connected to a working load; a mobile tensioning means equipped with a third supporting means (5c) of an intermediate section (3c) of the rope (3) interposed between the first and the second supporting means (5a, 5b), the third supporting means (5c) being taken in compression of the intermediate section (3c) through the action of elastic means (6); a measuring means adapted to measure a value χ of a linear distance d or an angular distance a included between a reference point and a position of the measuring means and to send such value χ to processing means adapted to indirectly compute a value σ of tension of the rope (3) through a function σ = f(x, k), where k is an elastic coefficient of the elastic means (6).
