ABSTRACT:
An apparatus for measuring tension in guy wire systems wherein the lower end of the guy wire has a thimble adjoined by a connection pin to a yoke or clevis of a turnbuckle shackle bolt connected to an earth anchor. A block assembly is removably received beneath the clevis and a thimble-engaging jaw assembly is removably received on the guy wire above the clevis. The block assembly and jaw assembly are connected at one end by a threaded rod assembly that includes a strain sensor connected with an indicator device, and by a threaded rod at their opposed end. The jaw assembly is drawn downward by adjusting nuts on the threaded rods beneath the block assembly to engage the thimble and move it downward transferring the tension to the threaded rod and threaded rod assembly which is sensed by the strain sensor and indicated by the indicator device.
