  • Patent number: 6220780
    Abstract: An apparatus and method is described for translocating a lane divider from an initial position to a final position on a roadway. The apparatus comprises a conveyor connected to a vehicle. The conveyor includes a receiving segment for receiving the lane divider from the initial position on the roadway and a discharging segment for discharging the lane divider to the final position on the roadway. The receiving segment and the discharging segment are pivotally connected relative to one another. The receiving segment may be pivoted to enable the lateral movement of the receiving segment to accommodate for variation in the initial position of the lane divider on the roadway. The discharging segment may be pivoted for discharging the lane divider to a final position aligned on the roadway. A translocating segment may be interposed between the receiving segment and the discharging segment for moving the lane divider from one lane to another lane on the roadway.
