The invention discloses an escalator with a bearing step segment non-dead-corner sensing mechanism. A lower horizontal segment, an inclined segment and an upper horizontal segment of the escalator are each provided with a sensing steel wire, the sensing steel wires are arranged below bearing steps, one end of each sensing steel wire is fixed to a bracket, the other end bypasses a rotary idler wheel and then is hung, the hung ends are tensioned with a heavy object, and a detection microswitch is arranged above the heavy object; and the detection microswitch is connected with a control system of the escalator, when any step level is broken or deformed at any position of the bearing segment of the escalator, the heavy object moves upwards under the tension of the sensing steel wires to trigger the detection microswitch, a signal is output, and the control system turns off electricity to stop the escalator. 本发明公开种带承载踏步区段无死角感应机构的自动扶梯，自动扶梯的下水平段、倾斜段、上水平段各设置感应钢丝，感应钢丝设置在承载踏步的下方，感应钢丝的端与支架固定，另端绕过可转滚轮后悬垂，悬垂端用重物张紧，重物上方设有检
