The invention relates to an escalator capable of giving a retrograde motion safety prompt. The escalator capable of giving the retrograde motion safety prompt comprises steps, cover plates, skirt panels, an escalator speech system and a gravity sensing device which is arranged below a tail end step in the running direction of the escalator, wherein the cover plates are located above the skirt panels and the escalator speech system comprises a speech control part; The speech control part comprises a gravity monitoring circuit which is connected with the gravity sensing device and is used for monitoring and recording a weight value applied to the tail end step of the escalator in real time; the speech control part further comprises a comparison circuit for generating alarm prompt signals; the escalator speech system further comprises a sounding part which is connected with the comparison circuit and is used for giving a speech prompt or a buzzer sound to prompt a person to not retrograde when the comparison circuit outputs the alarm prompt signals, the sounding part is fixedly installed in the cover plate or the skirt panel and is in contact with the inner wall of the cover plate or the skirt panel. By adopting the scheme provided by the invention, safety prompts and alarms for retrograde motion on the escalator can be given.
