<p><P>PROBLEM TO BE SOLVED: To provide a wire tightening method for performing the coupling work of a come-alongless metal fixed to a tension clamp and a parallel cleavis fixed to a vernier metal smoothly in wire tightening work using a four conductor tension device, and to provide a come-alongless metal for use therein. <P>SOLUTION: A wire tightening tool for coupling with a wheel 78 on the transmission line side is fixed to a come-alongless metal 76 while projecting downward in a vertical plane at an angle of about 90 degree to the wire tightening direction. A vernier metal 12 is constituted not to require a right angle cleavis by twisting the line side distal end for fixing a parallel cleavis 66 about 90 degree, and wheels 80 and 81 on the steel tower side are fixed not to the line side twin yoke 18 but to the inside of two vernier metals 12 and 13 of the upper wire side twin yoke 58 or the lower wire side twin yoke 70. When the wheels 78-81 touch the coupling metals, the wheels 80 and 81 are fixed to the outside of the upper wire side twin yoke 58 or the lower wire side twin yoke 70 by using an attachment. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
