Abstract
A method for stretching cables includes the steps of i) providing at least one first and one second stretching device; the first and second stretching device include at least one rotatable drum on which a cable can be wound or unwound; an electrical movement member associated to the drum for winding the cable; supply means connected to the movement member; a braking device associated to the drum and activatable for unwinding the cable; an energy recovery member associated to the drum and active simultaneously with the braking device for recovering energy during the unwinding of the cable; ii) activating the second stretching device for pulling the cable; iii) recovering energy from the first stretching device during the unwinding of the cable; and iv) transferring at least part of the recovered energy from the first stretching device to the second stretching device.
