The invention discloses a hoistway door unlocking device and a hoistway door unlocking method. The hoistway door unlocking device comprises a rotating bar and a rope. The rotating bar is provided witha first end, a second end and a connecting part located between the first end and the second end. One end of the rope is connected to an unlocking pull rod of a hoistway door while the other end of the rope is connected to the first end of the rotating bar. The connecting part of the rotating bar is rotatably connected to a longitudinal rod or a transverse rod of a crawling ladder in a pit of a lift well. Elevator maintenance staff can drag the rope by holding the second end of the rotating bar and the longitudinal rod or the transverse rod of the crawling ladder by a single hand and drive the unlocking pull rod to an unlocking position through the rope so as to unlock the hoistway door. According to the invention, one hand of the elevator maintenance staff holds the crawling ladder all the time in the unlocking process, so that the risk that the elevator maintenance staff falls from the crawling ladder can be avoided effectively, and the unlocking and door-opening steps of the hoistway door are simplified.
