An elevator comprises a steel wire rope, a counterweight, a lift car and a guide rail, one end of the steel wire rope is connected with the lift car of the elevator, the other end of the steel wire rope is connected with the counterweight, and the lift car linearly slides up and down along the guide rail. Each detection piece comprises a detection wheel, a detection rod, a shell and two first switches, the two detection pieces are oppositely arranged, the steel wire rope can penetrate through the centers of the two detection pieces, the detection wheel of each detection piece makes contact with the steel wire rope, the detection wheel is rotationally connected with the detection rod, the detection rod is slidably connected with the shell, and the two first switches are arranged in the shell. The two first switches are symmetrically arranged about the center of the shell, the brake part is in contact with the guide rail after being powered on so as to brake the lift car, when any position of the steel wire rope becomes thick or thin, the first switches are switched on and cannot be switched off without manpower, and the brake part is powered on for braking and serves as a fault alarm.
