Abstract: An example dock leveler for a loading dock includes a position sensor system that not only senses upper and lower travel limits of the dock leveler's deck and/or lip but can also sense a plurality of intermediate positions between the limits. In some examples, the system includes one or more cable-extension transducers that provide a feedback signal that varies as a function of the deck's position relative to a dock platform and/or varies as a function of the lip's position relative to the deck. Such a position sensor system makes it possible to operate the dock leveler automatically with little to no manual intervention.
