A portable barricade includes at least three legs that are operably coupled together to permit movement relative to each other between a collapsed state and an expanded state. The barricade is configured such that when in the collapsed state, the at least three legs are arranged with at least one of the legs stacked between at least two other legs to form a compact stack that facilitates portability of the barricade. The at least three legs are operably coupled together for rotation about a common axis. When the barricade is deployed to the expanded state, each leg is rotated about the common axis to spread the legs apart such that each leg is arranged at a different angular position about the axis relative to the other legs, thereby enlarging the footprint and/or enhancing stability of the barricade.

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.

Vehicle-mountable cargo carrier for portable rumble strips
A cargo carrier for portable rumble strips is mountable to a hitch assembly for a vehicle. The cargo carrier includes a basket configured to receive and retain a portable rumble strip for storage and transport, and a mounting assembly that includes a pintle adapted to be received in a receiver of a hitch assembly mountable to a vehicle. The basket has a frame that includes frame elements that define a bottom wall, relatively long front and back walls, and relatively short side walls that connect the front wall and the back wall. The front, back, and side walls extend from respective sides of the bottom wall in a common direction. And the basket further includes a rotating element at the top of at least one of the side walls to facilitate drawing rumble strips lengthwise over the side wall into or out of the basket.

A portable modular pedestrian ramp comprises a plurality of modular ramp units. Each of the modular ramp units comprises a pair of side edge plates each having inwardly facing sides to which opposite ends of decking are attached. The side edge plates of at least some of the modular ramp units have opposite ends thereof that are releasably connectable to one another by self-locking connectors to provide different ramp lengths without the need for any tools or fasteners to join the modular ramp units together or disassemble the modular ramp units for transportation and storage.
A barricade assembly comprises a pair of laterally spaced uprights for supporting at least one barricade board, and a foldable leg assembly for selectively supporting the uprights in a generally upright position. The leg assembly comprises two pairs of legs, one of which has a sliding connection with the respective uprights, and the other of which has a pivotal connection with the respective legs of the one pair and with the respective uprights. When the legs of both pairs are unfolded, the legs of both pairs support the uprights in a generally upright position, whereas when the legs of both pairs are folded, the legs of the one pair are nested within the legs of the other pair substantially in line with the inner sides of the respective uprights to provide a substantially flat barricade assembly for ease of stacking of a plurality of such barricade assemblies on top of one another during storage and/or transit.
Pedestrian barricade assembly includes a plurality of uprights and associated guide rails. Each upright includes a front section having one or more transversely extending channels. Each of the channels has a pair of laterally spaced semi-circular flanges in upper and lower side walls of the channels that are slidably engageable by upper and lower open notches adjacent end portions of the guide rails to provide hinge connections therebetween.

A portable highway warning device includes any number of elongated rumble strips each fabricated of a suitable flexible polymeric material. Embedded within each rumble strip are a plurality of laterally spaced metal plates or bars to provide ballast to each rumble strip. The metal plates or bars run transversely across the width of each rumble strip with sufficient spacing therebetween to permit each rumble strip to be rolled up lengthwise from end to end when not in use.
An inertial barrier includes a standard size plastic container and a single size insert that is supported by a ledge inside the container for supporting different amounts of sand or other dispersible granular energy absorbing material thereon to achieve different barrier weight configurations. The insert has an axially upwardly, radially inwardly extending top wall that permits some downward flexing of the insert inside the container as the weight of the material that is placed on the insert builds up, causing the sides of the insert to expand and push radially outwardly against the container side wall, preventing the material from leaking past the insert inside the container. Axially extending ribs may be provided in the container side wall for increased strength and rigidity.
Plastic blow molded board-like members include a plurality of longitudinally extending, laterally spaced aligned channels/grooves in opposite sides of the members. Each of the channels has closely spaced apart side walls and inner end walls. The inner end walls of aligned channels in opposite sides of the member are joined together to provide a relatively high strength reinforced core. The ends of the members are completely closed during the blow molding process for increased strength and to keep out dirt and moisture.
Plastic molded uprights and/or light and flag mounts may include stepped upper ends for mounting of a light thereon and/or laterally spaced apart oppositely downwardly angled flag mounting holes extending at least partway therethrough adjacent the upper ends thereof. One or more pairs of integral molded, axially spaced apart flanges may protrude outwardly from one of the front and back walls of the uprights for aiding in locating and supporting one or more barricade boards between respective pairs of flanges.
