The two detection devices 4 can respectively detect whether the retraction wire rope 21 and the tension wire rope 22 have broken. When any one of the retracting wire rope 21 and the stretching wire rope 22 breaks, the control device receives the detection signal from the detection device 4, and can cause the two brake devices to perform a braking action. Thereby, accidents caused by boarding bridge out of control can be avoided.
