Patent ID: 8631745

Claim:
A method for tensioning a cable using a tensioning installation comprising a mobile pulley over which said cable passes, a support trolley for said mobile pulley, on a guide rail running along a longitudinal axis between first and second end points so as to adjust the tension of the cable as a function of a set tension of the cable, and at least one linear actuator for moving the trolley along the longitudinal axis, said method comprising: coupling said at least one actuator in a first position between a first support point fixed relative to the rail and a second support point fixed relative to the trolley such that the trolley moves on a first segment of the rail extending between the first end point and an intermediate point and said at least one actuator is controlled as a function of the set tension of the cable; decoupling the at least one actuator from said first position; and coupling said at least one actuator, in a second position between a third support point fixed relative to the rail and a fourth support point fixed relative to the trolley, at least one of the third support point and the fourth support point being distinct from the first support point and the second support point such that the trolley moves on a second segment of the rail running between an intermediate point and the second end point and said at least one actuator is controlled as a function of the set tension of the cable.
