ABSTRACT:
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.
