METHOD FOR STRETCHING CABLES

摘要

A method for stretching cables comprises the steps of providing at least one first (If) and one second stretching device (la), which comprise each at least one drum (4) rotatable on which there can be wound or unwound a cable; an electrical movement member (5) associated to the drum (4) for allowing the winding of the cable; supply means (6) connected to the movement member (5); a braking device (10) associated to the drum (4) and activatable for allowing the unwinding of the cable; an energy recovery member (11) associated to the drum (4) and active simultaneously with the braking device (10) for recovering energy during the unwinding of the cable; activating said second stretching device (la) for pulling said cable; recovering energy from said first stretching device (If) during the unwinding of the cable; transferring at least part of said recovered energy from said first stretching device (If) to said second stretching device (la).
