The invention relates to a fall protection elevator. The fall protection elevator comprises an elevator car, a fixing rail and a rope head device. The fall protection elevator is characterized in that a fall prevention system is arranged on the elevator car; a ratchet guide rail is arranged on the fixing rail and stretches in the length direction of the fixing rail, the side, facing the mounting space, of the ratchet guide rail is provided with a plurality of ratchets at intervals, and the ratchets stretch over the side of the ratchet guide rail; the rope head device is arranged above the elevator car, and the fall prevention system does not make contact with the ratchet guide rail when the rope head device applies action force to the fall prevention system; and the fall prevention system is clamped to the ratchets of the ratchet guide rail when the rope head device does not apply action force to a guide rod. The invention further provides a method for preventing the elevator from falling. In this way, the fall prevention system is of a simple mechanical structure, all units can move without being controlled through control signals in the fall prevention process, and the reliability and stability of the whole system are improved.
