Portable Crash Cushion Trailer Now Easier to HandleAbstract:
The portable crash cushion trailer is a tilt-bed trailer equipped with a pallet of hinged steel plates. Sand-filled barrels are secured to the pallet, and a winch is provided to assist in installation and removal of the barrels. Rollers on the trailer bed allow the pallet to easily slide on and off the trailer. The second generation prototype of the portable crash cushion trailer is now ready for field testing. Initially developed as part of the Strategic Highway Research Program (SHRP), the device allows work crews to quickly deploy sand-filled barrels to close a traffic lane or shield construction equipment in a work zone.
