  • Patent number: 9174811
    Abstract: Example vehicle restraints with rotating and translating barriers are disclosed herein. An example vehicle restraint disclosed herein a main body installable at a loading dock and a barrier to be coupled to the main body. The barrier rotates about an axis relative to the main body between an upper blocking position to block the RIG and a stored position to release the RIG, where for a given elevation of the main body the barrier being higher in the upper blocking position than in the stored position. The barrier moves radially with respect to the axis.
    Type: Grant

  • Patent number: 8065770
    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.
