The invention discloses an anti-falling winding type elevator which comprises an elevator body. A lifting cavity which is through in the front-back direction and provided with an upward opening is formed in the elevator body, a lifting bottom plate is arranged in the lifting cavity in an up-down sliding manner, and anti-falling devices are arranged at the lower side of the lifting bottom plate ina bilateral symmetry manner; each anti-falling device comprises rotating cavities which are arranged at the lower side in the lifting bottom plate in a bilateral symmetry manner and provided with downward openings, chain wheel cavities are formed in the rear sides of the rotating cavities, and driven chain wheel shafts extending into the chain wheel cavities are rotatably arranged at the sides, away from the symmetry center, of the front end walls of the rotating cavities; and anti-falling rotating plates are fixedly arranged at the front sides of the outer circle faces of the driven chain wheel shafts. According to the anti-falling winding type elevator, when an elevator cargo loading box falls at an overspeed or falls accidentally, the anti-falling devices and rope clamping devices can be automatically started, the cargo loading box can be effectively prevented from falling continuously, and meanwhile, a broken steel wire rope can be clamped.
