Abstract: Based on the inquiry and research of testing the tension of loading rope by vibrating wave method, the paper puts forward the method of telemetering the vibrating frequency by YD-GDH-SC 16 system. It has been proved that this method has many advantages such as bigh suitability, safe reliability and high accuracy, etc in the practical test of a concerned project. With the adoption of such method, it would be more accurated than the vibrating wave method for those loading ropes having larger diameter, shorter crossing space and stronger tension.
