  • Device and method for testing the tension in stressed cables of concrete structure
    Patent number: 6880412
    Abstract: A device and method for testing the tension in a stressed cable of a concrete structure. The device includes a frame and a hydraulic jack mounted onto the frame. The hydraulic jack applies a force to the stressed cable and displaces the stressed cable laterally. A hook or clamp is connected to the hydraulic jack for grasping the stressed cable in order to apply the force thereto, and a dial gauge is mounted onto the frame for measuring the deflection of the stressed cable once the force has been applied. The amount of pre-stress within the stressed cable can be calculated by measuring the amount of deflection caused to the stressed cable by the force of the jack.
