The invention relates to an electric rotating crane, which comprises a casing, a winding tube, a motor, a speed reducing machine, a steel wire rope, a pulley and a hanging hook, wherein the winding tube is coaxially arranged in the casing in a penetrating way, one end of the winding tube is provided with a support shaft, the support shaft is supported on the side wall of one end of the casing through a bearing, the outer end of the support shaft is coaxially connected with one connecting shaft in a penetrating way, the connecting shaft is connected with a height limiter arranged outside the side wall of one end of the casing, the speed reducing machine is fixedly connected onto the side wall of the other end of the winding tube a penetrating way, and is a planetary speed reducing machine, a casing of the speed reducing machine realizes the coaxial transmission with the winding tube through the side wall of the other end of the winding tube, the motor is arranged on the side wall of the other end of the casing, and the motor is in coaxial output connection with the speed reducing machine. After the motor transmits the speed reducing machine, the casing of the speed reducing machine realizes the coaxial transmission with the outer wall of the winding tube to drive the winding tube to realize large-torque transmission winding placement, the planetary speed reduction is carried out, in addition, the operation of the winding tube is stable and safe through casing transmission, and the integral service life is favorably prolonged.
