The invention relates to a winch, in particular to a double-winding-drum transmission device of a motor-driven winch. The transmission device comprises a reduction gearbox and a double-winding-drum wire reel. The reduction gearbox comprises a shell; a gear shifting shaft, a first input shaft, an intermediate transmission shaft, an output shaft and a brake shaft are installed in the shell through first bearings, the gear shifting shaft, the first input shaft, the intermediate transmission shaft and the output shaft are parallel with one another, and the brake shaft is fixed in the shell; a speed changing power output triple gear and a reversing dual gear are installed on the first input shaft, and a speed changing sliding triple gear and a reversing sliding dual gear are connected to the gear shifting shaft through splines; a reversing idle gear is installed between the reversing dual gear and the reversing sliding dual gear through a rotating shaft. According to the transmission device, the reversing sliding dual gear is adopted, and the transmission ratio of the reversing sliding dual gear to a gear on the left side of the reversing dual gear is equal to that of the reversing sliding dual gear to a gear on the right side of the reversing dual gear to the idle gear, so that the speed of a forward gear of the winch is equal to that of a reverse gear of the winch, and operation is facilitated for operators.
