The invention discloses an escalator with a main driving chain bi-direction deviation monitoring device. Detection switches are arranged on two sides of the middle position of a main driving chain correspondingly. Each detection switch is provided with a trigger rod. The distance between each trigger rod and the main driving chain is a set value. The detection switches are triggered when deviationof a chain running track exceeds the set value. The detection switches are connected with a controller of the whole escalator and sends out an escalator stopping signal. The escalator has the advantage that the safety of the escalator is improved.
