Abstract:
A system for retrieving a portable rumble strip from a roadway includes a carrier mountable to a vehicle for transporting retrieved portable rumble strips and a winch mountable to the carrier. The carrier has a support surface configured to support a rumble strip. And the winch includes a rotatable drum and a lead with a major dimension being a length dimension. A proximal end of the lead is connected to the drum such that rotation of the drum winds the lead about the drum. A hook is connected to a distal end of the lead opposite the proximal end. The hook is configured to engage and hold a portable rumble strip as the drum rotates to draw the lead and the hook to the winch, thereby drawing the engaged portable rumble strip into the carrier.
