2- Device (10), according to claim 1, is characterized by the fact that coupled to axis (84) and rod (90), respectively, are provided:
3- Device (10), according to claim 1, is characterized by the fact that the earthing and idler tension array, also assembled with the feeding system (54) fitted into pivot (46), operates as a pendulum, being responsible for the whole balance of the array.
4- Device (10), according to claim 1, is characterized by the fact that said wheel (42) is produced from a metallic conducive material and all the other components are produced from isolating material.
5- Device (10), according to claim (1), is characterized by the fact that the tension of the said feeding system (54) is transferred to activating engines (26, 28) and to said tightening and loosening tool (74) through control boxes (88) by means of parallel wire.
