ABSTRACT:
A crash attenuator for an exposed end of a concrete highway barrier includes a light weight array of sheet metal energy-absorbing elements interposed between diaphragms. The crash attenuator is cantilevered from one end of the barrier by a mounting arrangement that includes mounting tubes on the barrier and the attenuator that can be quickly secured together by removable pins. The energy-absorbing elements define a single row of tubular columns in forward portions of the crash attenuator and two rows of tubular columns in rearward portions of the crash attenuator. Vehicle deflecting members extend between the barrier and the crash attenuator and can fold against the barrier for storage.
