<p>PROBLEM TO BE SOLVED: To enable a jumper clamp itself to absorb the vibration of a jumper wire by hanging down the clamp body for a jumper wire movably through a vibration absorbing mechanism, to the section coupled with the arm part of a steel tower. SOLUTION: A clamp body 1 is hung down through a shock absorber 3 from a mounting member 4 on the steel tower side attached to the arm part on the side of the steel tower, and a coil-shaped spring 2 is interposed between the top flange and the bottom flange of the shock absorber 3. The shock absorptive jumper clamp constituted this way fulfills its function, holding the jumper wire with the clamp body, and being hung down from the arm part of the steel tower by a mounting member 4 on the steel side. Now, in the case that vibration adds to the jumper wire, the shock absorber 3 and the spring 2 expand and contract, receiving the vibration, and can attenuate and absorb the vibration with its energy loss, in its turn it does not give repeat distortion fatigue at the clamp section to the jumper wire.</p> |
