The invention discloses a motorized winch and a hoisting system, relates to the technical field of winches, solves the problem that an existing motorized winch is poor in emergency capacity under the lowering working condition, and improves the safety of the winch under the lowering working condition. According to the specific scheme, the device comprises a winding drum, a driving mechanism used for driving the winding drum to rotate and over-speed wheel stopping mechanisms arranged at the two ends of the winding drum, each over-speed wheel stopping mechanism is composed of a rotating disc and a brake disc, and the rotating discs and a rotating shaft of the winding drum are coaxially arranged and fixedly connected; a plurality of cams capable of accelerating upwarping are arranged on the outer surface of the rotating disc at intervals in the annular direction, the brake disc is located on the outer side of the rotating disc, the brake disc and the rotating disc are coaxially arranged, the brake disc is fixedly arranged, and a plurality of stop blocks are fixedly arranged on the inner wall of the brake disc at intervals in the annular direction; and a gap allowing the cam in a non-tilting state to pass through is formed between the stop block and the rotating disc.
