A hydraulic control arrangement for operating a winch with an adjustable hydraulic motor in the easing, hoisting and mooring modes. The arrangement comprises a pilot controller with a control lever which can be actuated as desired and can be deflected from a neutral position in opposite directions over a specific easing angle range and over a specific hoisting angle range. Previously, for the mooring mode, the control lever was blocked at a desired point in the hoisting angle range. The control lever, as viewed from the neutral position, can be deflected over a mooring angle range on the other side of the hoisting angle range, with increasing deflection of the control lever in the mooring angle range, the hydraulic motor being adjusted in the direction of a greater absorption volume and therefore in the direction of a greater torque and increased tension on the hawser. This contradicts the usual concept that as the deflection of a control lever increases, that is as the pivoting angle increases, the variable controlled by it also increases.
