The invention provides a large-lifting-height electric hoist which comprises a fixing frame and a driving component, and the driving component is arranged at one end of the fixing frame. The main winding drum is connected with the driving component, and power generated by the driving component drives the main winding drum and the driven winding drum to rotate synchronously; a first movable pulley and a second movable pulley are respectively arranged at two ends of the lifting hook; one side of the steel wire rope penetrates through the first movable pulley, the fixed pulley and the second movable pulley, and meanwhile the two ends of the steel wire rope are connected to the main winding drum and the driven winding drum respectively; when the main winding drum and the driven winding drum synchronously and reversely rotate, the two ends of the steel wire rope can be synchronously released or withdrawn, and under cooperation of the fixed pulley, the first movable pulley and the second movable pulley, the steel wire rope drives the lifting hook to ascend and descend; when the lengths of the main winding drum and the driven winding drum are equal to the length of the single winding drum, the lifting height of the single winding drum is twice that of the single winding drum.
