The invention provides a falling-preventing safety elevator which comprises an elevator supporting frame, an elevator car and a controller. The elevator supporting frame comprises a bottom plate, supporting stand columns and a reinforcing top plate, wherein the supporting stand columns are fixedly arranged at the four corners of the bottom plate, and the reinforcing top plate is arranged at the top ends of the supporting stand columns. Each supporting stand column is evenly and fixedly provided with a plurality of rotatable elastic speed reduction bars from bottom to top. The length of each elastic speed reduction bar is not larger than one half of the length of a horizontal connection line of the supporting stand columns at two opposite corners. The upper surface and the lower surface of each speed reduction bar are each fixedly provided with a speed sensor. The speed sensors are in communication connection with the controller. The elevator car is mounted on sliding rails of the supporting stand columns in a lifting mode. According to the falling-preventing safety elevator, the rotatable elastic speed reduction bars are mounted in the sliding rails of the elevator, so that speed reduction in falling of the elevator or goods or passengers is achieved.
