An electric winch device including an electric motor that rotates a winch drum in a hoisting direction, and generates regenerative electric power when a rotation of the winch drum in a lowering direction is transmitted to the electric motor, a transmission device that transmits the rotation between the electric motor and the winch drum, a power calculating section that calculates power of the target object by freefall, and a control section that controls an operation of the transmission device. When the power calculated by the power calculating section exceeds reference electric power, the control section causes the transmission device to change the transmission rate of the rotation to a transmission rate at which the regenerative electric power generated by the electric motor is equal to or smaller than the reference electric power.
