Winch system control mechanism for the simultaneous control of two winch motors

摘要

A winch system control mechanism for the simultaneous control of two winch motors includes a servo valve which is connected to an adjustable cylinder double drive pump for regulating the fluid pressure delivered from the pump to a winch motor driving a respective winch drum over which the respective cable or rope is engaged. A control means in the form of a shiftable hand lever is movable on either side of a neutral position in order to effect a heaving of the drum or a veering of the drum by regulating the position of the servo valve. The arrangement includes a control mechanism connected between the control means for the servo valve of each of the winch motors which operates to permit a varying of the driving pressure fluid which acts on the drum in accordance with the heaving or veering pressure produced on the associated winch drum by the action of the cable or line so that the fluid pressure acting on a first winch motor is controlled as a function of the tension of the rope on the other winch drum causing a reverse rotation of this drum and a build up of the pressure in the system which effects a change in the heaving operation of the first drum.
