<p>A control device and system for controlling a suspended load of a container crane with a trolley (21), a spreader (15) and load lines arranged in a four point suspension (4a-4d) for lifting a load and an optical sensor (5) for sensing a deflection position of an orthogonal axis (X,Y,V) of a container (20) suspended under the spreader. Two or more actuators (16-19) are arranged attached to at least one load for moving at least one said suspension point closer to or farther away from an imaginary centre line (XL,YW,VH) by shortening and/or lengthening the at least one load line.
