Apparatus and method for retrieving traffic cones from roadway surfaces comprises a framework which is adapted to be attached to a roadwork vehicle so as to be movable therewith along a roadway surface. A knock-down bar upon the framework knocks down a normally upstanding traffic cone, and a substantially horizontally oriented, substantially conically configured spearing mechanism mounted upon the framework is inserted into the hollow interior of the traffic cone. The spearing mechanism and traffic cone are pivoted to a vertical orientation, and subsequently elevated so as to place the traffic cones onto a platform in a nested stacked array.

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.

Apparatus for depositing or placing traffic cones onto a roadway surface at predeterminedly spaced locations thereof comprises a horizontally disposed magazine, and a vertically oriented chute section. A plurality of traffic cones can be loaded into the magazine section, and a leading one of the traffic cones can be moved into the vertically oriented chute section for discharge and deposition onto the roadway surface. An automatic control system can also be used to control the discharge of the traffic cones into the vertically oriented chute section in accordance with predeterminedly timed sequences such that the traffic cones can be placed upon the roadway surface at locations which are spaced apart by predeterminedly defined distances.

Temporary raised pavement marker (TRPM) applicator machine for automatically applying pavement markers to road surfaces

Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises primary and auxiliary conveyors wherein an upstream end portion of the primary conveyor is able to extend, for example, over the rear bed portion of a roadwork truck so as to permit an operator, stationed upon the bed portion of the truck, to deposit pavement markers upon the primary conveyor. In accordance with a first embodiment of the invention, a slide mechanism is disposed adjacent to a downstream end portion of the primary conveyor and adjacent to an upstream end portion of the auxiliary conveyor for transferring pavement markers from the primary conveyor to the auxiliary conveyor when the absence of a pavement marker upon the auxiliary conveyor is detected. When pavement markers are present upon both conveyors, the pavement markers are conducted to applicator mechanisms for application to the roadway surface. A second embodiment of the invention comprises the use of a pair of wheel applicators for applying the temporary raised pavement markers (TRPMS) to the roadway surfaces.

Apparatus for removing protective coverings from temporary raised pavement markers (TRPM) fixedly secured upon roadway surfaces comprises a platform, and a plurality of toothed implements disposed beneath the platform for encountering and removing the protective coverings mounted upon the upstanding vertical reflective portions of the temporary raised pavement markers (TRPM). The toothed implements are mounted upon a chain which is driven by a motor mounted upon an upper surface portion of the platform, and a blower is also mounted upon the upper surface portion of the platform. An exhaust duct, fluidically connected to the intake side of the blower, passes through a suction port defined within the platform so as to be fluidically connected to the underside of the platform, and in this manner, the removed protective coverings of the temporary raised pavement markers (TRPM) may be removed from the roadway surface and conveyed to a suitable debris collection bag.

Machine for automatically removing the protective coverings from temporary raised pavement markers (TRPMs)

Apparatus for removing temporary raised pavement markers (TRPM) from roadway surfaces comprises a platform, and a plurality of cutter blades rotatably disposed beneath the platform for encountering and severing the upstanding vertical reflective portions of the temporary raised pavement markers (TRPM). The cutter blades are driven by a motor mounted upon an upper surface portion of the platform, and a blower is also mounted upon the upper surface portion of the platform. An upstream intake duct, fluidically connected to the intake side of the blower, passes through a rear end portion of the platform so as to be fluidically connected to the underside of the platform, and in this manner, the severed upper reflective portions of the temporary raised pavement markers (TRPM) may be removed from the roadway surface and conveyed to a suitable debris collection bag.
