A reel transport alignment system wherein movable structure carries a reel such as a winch or a capstan, either of which is provided with a flexible elongate member such as a cable that is to be maintained and anchored at a fixed point spaced from the movable structure. The reel, e.g. winch or capstan, as the case may be, is revolved so that the primary structure advances toward the anchor point of the cable by the reel wrapping or winding up the cable in such a manner that the primary structure advances forwardly. Means are provided which cooperates with the cable and senses any askew orientation thereof relative to the instantaneous orientation and direction of movement of the primary support structure so that there is set in motion a function or series of functions whereby the primary structure is realigned so that its general orientation and direction of travel is essentially rectilinear with the cable. In this way, the deviations of the instantaneous orientation of the primary structure carrying the reel, be it capstan or winch, are automatically corrected by the automatic sensing device, cooperable with the cable, being used to control a valve or other control element for correcting the direction of travel of the primary structure so that it moves in a desired direction, i.e., advances along the cable in a straight line toward the cable's anchor point.
