The winch converts electrical energy into mechanical energy through motor 1, that is, the rotor of the motor rotates and outputs, and drives drum 6 to rotate after decelerating through V-belt 2, shaft 3, gear 4 and gear 5. The drum winds the steel wire rope 7 and passes the pulley blocks 8 and 9 to make the crane hook 10 lift or drop the load Q, convert the mechanical energy into mechanical work, and complete the vertical transportation and loading and unloading of the load.
