  • Apparatus for retrieving conical roadway warning markers
    Patent number: 6056498
    Abstract: An apparatus which automatically retrieves conical highway warning markers from the roadway and transports the cones to a support vehicle for storage. The apparatus, which is attached to a vehicle, comprises a clamping plate disposed at the end of a lifting arm, which clamps the base of the traffic cone onto a platform. The lifting arm then rotates to raise the cone to a position for stowage. The raised cone can then be manually removed from the lifting arm for stowage or, alternatively, dropped onto a conveyor system which transports the traffic cone to a storage area within the vehicle.
