发明名称 Transversely extending pivotal hitch mechanism
摘要 Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises a conveyor upon a wheeled vehicle wherein an upstream end portion of the conveyor is able to extend, for example, over the rear bed portion of a roadwork vehicle so as to permit an operator, stationed upon the bed portion of the roadwork vehicle, to deposit pavement markers upon the conveyor. A pair of wheel applicators are used for applying the temporary raised pavement markers (TRPMs) onto the roadway surface. A hitch mechanism is also used to provide hinged movement between the tow bar of the towed wheeled vehicle and the mounting bar of the towing roadwork vehicle so as to permit independent elevational movement of the towed wheeled vehicle relative to the towing roadwork vehicle.
