Abstract
A method for tensioning a cable uses a tensioning installation comprising a pulley over which the cable passes, a support trolley for the mobile pulley, on a guide rail and one or several linear actuators to move the trolley. The method allows for coupling an 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 and the actuator is controlled as a function of the set tension of the cable decoupling the actuator from its first position; and coupling an 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 or 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 and the actuator is controlled as a function of the set tension of the cable. A cable tensioning installation and a cable transport installation are described.
