    Prestressed anchor cable (pole) tension detector

    Device name
    Prestressed anchor cable (pole) tension detector


    Test object: Anchor cables (rods) in bridges, tunnels, ports, slopes, mountain reinforcements, etc.

    Test content: Anchor effective prestress


    Test items



     Related patents

    Patent name: A non-destructive testing method for testing the tension of prestressed anchor system



     Equivalent mass method

    When the anchor head is excited, the vibration system induced by the anchor cable is not fixed, but changes with the change of the anchoring force. The greater the anchoring force, the greater the mass involved in free vibration.

     Test principle and method


     Achievements and technical characteristics

    Accurate test, the test accuracy is over 90%;

    Wide testing range and tension range from several tons to several hundred tons;

    Simple and fast operation, good reproducibility, and small human influence factors;

    The main components are imported from the United States and Japan, with high reliability and durability.


     product description


    Sichuan Shengtuo Testing Technology Co., Ltd. provides prestressed anchor cable tension detector. This equipment is mainly used in the quality inspection of anchor rods (cables) in bridges, tunnels, ports, slopes, mountain reinforcements and other projects. It can also be used for tension bars in building structures and bolt tension in the machinery industry.
