In this paper we have measured not only the vibration of a cage by a accelerometer,but also the vibration of a winding rope by b photoelectric-tube-strain-meter and compared the experimental results with the value obtained through theoretical calculations. Some results we have obtained through our researches are as follows; 1) By an accelerometer with low free frequency we can not exactly measure the vibration of a winding rope in loading,for the free vibration of the accelerometer is resonant
