The invention provides an electric winch with multiple working modes, which belongs to the field of transport machine freight winch equipment, and comprises a hand-cranking device, a steel rope arranging and winding mechanism, a working mode conversion device, a winding drum assembly and two shell assemblies, and the winding drum assembly is positioned between the two shell assemblies; the hand-cranking device, the steel cable winding mechanism, the working mode conversion device and the motor base assembly are installed on the shell assembly. The hand-cranking device is used for manually providing torque in a power-off state and has an anti-reversion function; the steel cable arranging and winding mechanism is used for arranging and winding a steel cable on a winch drum according to a preset arranging and winding track; the working mode switching device is used for switching three working modes, namely an electric working mode, a manual working mode and a neutral gear mode, and can adapt to various working modes such as electric working, manual working and steel cable maintenance; according to the motor base assembly, two three-phase alternating-current motors drive a differential gear train to achieve the dual-redundancy transmission function. The overload protection device is used for transmitting torque under a preset load, idling and slipping in an overload state, and preventing the winch from being damaged when overload occurs; the winding drum assembly is provided with a guide groove and can be matched with the steel cable arranging and winding mechanism to achieve automatic and neat arranging and winding of multiple layers of steel cables.
