An emergency response barrier is shown and described, the barrier having a cab and engine for propelling the barrier; a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; wherein the frame is covered with a substantially planar skin that extends along the right and left sides of the frame, from a top of the frame down to a lower edge and covers a majority of the wheels on each side of the barrier; an impact attenuator coupling on the frame, having a vertical pin received in a bore disposed on an impact attenuator, and configured for rotation about the vertical axis of the pin; and a hydraulic cylinder connected between the frame and the impact attenuator, wherein retraction and extension of the hydraulic cylinder moves the impact attenuator through an arc of rotation about the vertical pin.

A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a ballast coupled to the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein the vehicle is provided with an mechanism for locking and unlocking the brake system.

The present invention provides a barrier comprising a plurality of individual barrier units in a linear arrangement and a relatively rigid energy transfer means wherein the energy transfer means comprises at least one continuous member extending along the length of the plurality of individual barrier units that is connected to each individual barrier unit in the plurality, such that when a force is applied to one individual barrier unit in the plurality, the energy transfer means transfers part of the energy associated with the applied force to other individual barrier units in the plurality of individual barrier units. Also provided is the use of such a barrier to resist vehicle ramming attacks, a method of deploying such a barrier and a kit containing the components of such a barrier.

Right and left safety module embodiments are designed to be installed in insets located midway along right and left sides of flatbed trucks. The modules provide man baskets that have lower and upper platforms. While the truck is being driven alongside a roadway work zone, a workperson standing on the module's lower platform either 1) moves traffic delineators one at a time from the upper platform, and then places the delineators at spaced locations alongside the roadway work zone, or 2) removes traffic delineators one at a time from spaced locations alongside the roadway work zone, and then places the delineators onto the upper platform. Vertically movable safety rails and pivotal safety gates of the modules prevent falls from the modules of workpersons standing on the lower platform.

A safety trailer including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein each wall section has a lower bracing section comprising a single horizontal beam, two diagonal braces and a plurality of cross-braces, to allow workers in the protected work area to access a portion of the area under the wall section.

A safety trailer including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein each wall section has first and second end members, each of the first and second end members comprising an outwardly projecting alignment member and an alignment-receiving member, the first and second end members having the alignment and alignment-receiving members positioned in opposing configurations.

A mobile barrier is shown having first and second platforms, at least one of the first and second platforms engaged with an axle and a set of wheels; a safety wall assembly, having a mechanism for translation of the safety wall from one side of the platforms to another, the safety wall further having telescoping first and second portions allowing the safety wall assembly to expand and retract in length along the longitudinal axis of the mobile barrier; a plurality of variable length braces connected to the platforms and the safety wall, which expand and retract as the safety wall moves from one side of the platforms to the other.

A safety truck includes: an over-cab storage rack to store nested stacks of barrel-type safety barriers; a man basket mounted within an inset formed in a flat bed of the safety truck along the left or right side of the safety truck to provide a support platform below the flat bed to enable personnel to ergonomically place the barrel-type safety barriers on a roadway; a sign cage mounted to the flat bed to store components of warning signs; a display board that includes speed detection radar to detect a speed of a vehicle approaching the safety truck, at least one display device to display a message readable from behind the safety truck, and a camera to capture an image of the approaching vehicle; and/or a truck-mounted attenuator connected to the rear of the safety truck to absorb kinetic energy of the approaching vehicle colliding with the TMA.

A crash attenuator for decelerating an impacting vehicle includes a first end that can be releasably secured to a vehicle, and a second end that is longitudinally spaced from the first end. The second end includes an impact member that is movable in the longitudinal direction from a pre-impact position to an impact position. At least a pair of spaced deformable attenuator members extend in a longitudinal direction and have a proximal end and a distal end. The proximal ends are staggered downstream from the impact member in the pre-impact position. At least a portion of the deformable attenuator members are bent in a non-outboard direction as the impact member is moved from the pre-impact position to the impact position.
