  • Patent number: 8061926
    Abstract: A crash barrier beam (10) suitable for temporary placement on a road comprises a housing (18) which, in profile, has a laterally extending base (12) for contact with the road. The beam has a narrower central element (14) upwardly extending from the base that terminates in a top portion (16). The exterior of the housing provides a continuous impact surface to an oncoming vehicle and the profile provides stability to the beam on impact. The crash barrier beam (10) has a length defined by a first end (24) and a second end (26, 28). At least one of the first and second ends comprises formations (32, 34) for engagement with corresponding formations (38, 40) on an end of an adjacent beam (10?) so as to facilitate joining of the beams to one another. The formations are configured for the beams to be substantially self-aligning with respect to each other.
