The present invention is provided to engage the drum, the motor, the motor and the drum of the drum generates a rotational driving force to be rotated is rotatably installed connected to the base frame, the base frame, a drum in a state in which reduced rotation speed transmitted from the motor of reducer delivery to, and installation coupled to the shaft portion of the reducer, is installed connected to the hydraulic pump so as to supply the operating fluid to the hydraulic pump, a hydraulic pump that works in conjunction with the rotation of the drum, seungha pulpit when the rope pay-off of the water falling , hydraulic pressure to keep constant the flow rate discharged from the hydraulic pump regardless of the rotational speed increase of the drum, while reducing the rotational speed of the reducer is connected with the hydraulic pump so that elevating the object is moved down at a constant rate to adjust the driving speed of the hydraulic pump It provides a marine winch comprising control parts.
This, ship winch, installation connecting the hydraulic pump to work the reduction gear and the hydraulic pump is a driving speed controlled by a hydraulic control unit. Thus, even if the elevating object is falling from the drum while the rotational speed of the speed reducer connected to the bar, the hydraulic pump in which the driving speed of the hydraulic pump does not increase by the oil pressure control unit also does not increase the elevating object at a constant speed stable descent to be fulfilled.
