<p><P>PROBLEM TO BE SOLVED: To establish a partial suspending tensile cabling technique for developing a place where a suspending metal wheel is suspended by setting a span with an important lateral article as an object, and for collectively tensile cabling a strung wire for the whole span for rationalizing (simplifying, power saving and efficiency making) the suspending technique, for suspending the suspended metal wheel between steel towers and extending the strung wire for the whole span in an extension construction of a transmission line. <P>SOLUTION: In the suspended metal wheel 1 with an inversion device 5, a metal fitting with which a circular metal wheel 4 is always inverted to a constant direction, is attached to the circular metal wheel 4 by tension fluctuation of a bus-bar 8 or the strung wire 12 suspending the circular metal wheel 4 used for the suspended metal wheel 1, and is suspended only in the required span. The inversion device 5, a counter weight 05 and a running board are slimmed and lightened for improving a passage characteristic of the strung wire 12 into the suspended metal wheel 1. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
